  5. The previous two blog posts describe how a Stack Based Buffer Overflow vulnerability works on x86 (32 bits) Windows. In the first part, you can find a short introduction to x86 Assembly and how the stack works, and on the second part you can understand this vulnerability and find out how to exploit it. This article will present a similar approach in order to understand how it is possible to exploit this vulnerability on x64 (64 bits) Windows. First part will cover the differences in the Assembly code between x86 and x64 and the different function calling convention, and the second part will detail how these vulnerabilities can be exploited. ASM for x64 There are multiple differences in Assembly that need to be understood in order to proceed. Here we will talk about the most important changes between x86 and x64 related to what we are going to do.

  10. With WPA3, Wi-Fi security is about to get a lot tougher Finally, a security reprieve for open Wi-Fi hotspot users. By Zack Whittaker for Zero Day | January 8, 2018 -- 22:28 GMT (22:28 GMT) | Topic: Security At last, Wi-Fi security -- or lack of -- is about to get its day in the sun. The Wi-Fi Alliance, an industry body made up of device makers including Apple, Microsoft, and Qualcomm, announced Monday its next-generation wireless network security standard, WPA3. The standard will replace WPA2, a near-two decades-old security protocol that's built in to protect almost every wireless device today -- including phones, laptops, and the Internet of Things. SECURITY 101 One of the key improvements in WPA3 will aim to solve a common security problem: open Wi-Fi networks. Seen in coffee shops and airports, open Wi-Fi networks are convenient but unencrypted, allowing anyone on the same network to intercept data sent from other devices. WPA3 employs individualized data encryption, which scramble the connection between each device on the network and the router, ensuring secrets are kept safe and sites that you visit haven't been manipulated. Another key improvement in WPA3 will protect against brute-force dictionary attacks, making it tougher for attackers near your Wi-Fi network to guess a list of possible passwords. The new wireless security protocol will also block an attacker after too many failed password guesses. WPA2, the current incarnation of the wireless security standard since 2004, uses a four-way handshake to securely allows new devices with a pre-shared password to join a network. The newer WPA3 will use a newer kind of handshake, Mathy Vanhoef, a computer security academic, told ZDNet, which will "not be vulnerable to dictionary attacks." A new wireless security standard can't come soon enough. A few months ago Wi-Fi security was under scrutiny amid a security vulnerability in WPA2, discovered by Vanhoef, which put every WPA2-compatible device -- including routers, phones, and computers -- at risk of hijack. The new WPA3 security standard is expected to land in devices later this year. Sursa: http://www.zdnet.com/article/wpa3-wireless-standard-tougher-wifi-security-revealed/

  15. Ham Radio for Emergency Communications SEPTEMBER 26, 2017 | MARK WAGGONER Get the latest security news in your inbox. Why have an article on Ham Radio on an InfoSec blog? As IT/IS professionals we tend to be some of the most “connected” people in society. We usually have several communication devices within arms reach at any time, and rely on them to constantly update and alert us. Though many of us even work directly with infrastructure, we tend to take it for granted. I’m sure many of us cringe when we have a brief outage - it may wreck your 99.99% uptime. But, what do you do when all that underlying infrastructure is gone, or at least not operational? How do you communicate when you have no internet or cell service? The recent hurricanes have brought this possibility home for a large number of people. Amateur Radio, commonly referred to as Ham Radio, has some answers for this type of dilemma. I’m sure some of you are thinking of an old guy in a shack with some huge, vacuum tube radio and a giant tower with antennas on it. Well, there are some of those around, but there is far more to Amateur Radio, particularly when it comes to Emergency Communications (EMCOM). Let’s start with a quick overview of the Amateur Radio Service. Ham Radio is a huge hobby with considerable width and breadth, as such, I’m going to use lots of generalization and gross simplification. But it starts with passing an exam and being licensed by the FCC. Exams must be taken in person and on paper generally. The American Radio Relay League has a list of exam providers and locations. The exams are based on a published question pool and the fee for the exam is between free and $15. There are three levels of licensing: Technician, General,and Extra that grant the ability to use different allocations of the radio spectrum. The exams are not difficult, they are multiple choice and there are lots of study resources available, including mobile apps. There is no requirement to send Morse Code anymore! Once you pass your test, you do have to wait a few days to get your license and callsign, these are published on the FCC’s website; my entry is here. The Technician license gives you access to Ham Radio Bands in the VHF/UHF range (30mhz - 10ghz). Radio waves in this range are generally line of sight (LoS). You must have an unobstructed path between your transmitter and the receiver at the destination. This is what you have probably experienced with GMRS/FRS radios (which are UHF). In order to extend the range and usefulness of LoS communications, repeaters placed in elevated locations are used. This can be extended even further with the use of linked repeaters. Repeaters do exactly what their name sounds like, they receive your signal and then re-broadcast it. As licensed operators, we also have the ability to use far more power (up to 1500 watts) than the GMRS/FRS radios (about 1 watt). Systems based on these frequency ranges are used for local communications, generally within a metro area. The General license type gives you access to the HF bands (1mhz - 29mhz). In this frequency range the radio waves travel by skywave instead of LoS. This allows you to potentially talk around the world by bouncing radio waves off of the ionosphere. The distance and direction of your communications are heavily dependent on the condition of the ionosphere. Things that affect the ionosphere: Day vs. night, sunspots, solar flares, solar storms. Check out some space weather reports. The Extra license adds some small allocations within the same bands the General has access to. Local For many people, the ability to get in touch with loved ones in their local area after a disaster is their primary concern. Close behind that is getting information on what is going on, what the response to the disaster is. These needs can be addressed with a Technician’s license and equipment that can only operate in the VHF/UHF bands. Most metro areas have linked repeaters systems that are hardened for EMCOM use. This includes a backup power source like a generator with days/weeks worth of fuel or a solar/battery system. During an emergency, traffic on these repeaters may be restricted at times so that your local ARES/RACES organization may be using them for official traffic in response to the disaster. Listening in can give you valuable information about what is going on with relief efforts. In order to be able to take advantage of these systems you are going to need a few things: Radio Power supply Antenna Frequencies Radios for these bands come in two form factors, the handheld HT (Handy Talkie in Ham Radio jargon), and the mobile form factor, about the size of a car stereo. These are usually single mode, FM radios, that are either single or multi-band. Most new Ham’s these days seem to start off with something like the Baofeng UV-5R, for around $20. But, you get what you pay for. Something like the Yaesu FT-60 would probably be a better HT to start out with, at around $150. Handhelds range all the way up to around $600 for the Kenwood TH-D74, which is serious overkill for most people starting out. One of the advantages of handhelds is that they are self-contained (radio, battery, antenna). The disadvantage is that they are low powered (4-8watts typically). My Ham Radio setup, pretty basic but it works. Yaesu FT-817, TyT 9000, BaoFeng UV-82HP, TyT MD-380 Mobile radios are often used as desktop radios as well as mobile. They are generally also single mode and either single or multi-band. These range from cheap Chinese radios (about $100), to high end Japanese ones ($600+). With these radios you will also need an antenna and a 12v power supply. The antenna could span from an outdoor one on a mast, to a mobile antenna mounted in your home, to a roll up style portable antenna. Power supply can be handled by either a purpose built unit, or a suitable battery and charger. The advantage to a mobile setup at home is greater power (40-80 watts), disadvantage for EMCOM is they use more power. While it is certainly possible to use a scanner or SDR (Software Defined Radio) to hunt for frequencies in use in your local area, it is far easier to start with a list you can program into your radio. Sites like www.radioreference.com help with finding local frequencies, also joining a local club can help (I belong to www.papasys.com here in Los Angeles). Please, do not make the mistake of thinking you can buy all this stuff and tuck it away until you need it. It takes practice and experience to effectively communicate with radios and troubleshoot issues. Long Distance Long distance communications via Ham radio is the realm of the HF (High Frequency) bands. Amateurs often use the approximate length of one wave as shorthand to refer to each band. The radios referenced above typically operate on 2m and 70cm bands. HF radios are capable of operating on bands between 160m to 10m. Why I bring this up is that the size of the antenna needed is directly related to the wavelength. Most antennas are either ½ or ¼ wavelength in order to be resonant. So, while a ½ wave antenna for a 2m radio is only about 3 feet long, one for the 40m band is 70 feet long. This can be a serious limiting factor for your use of these bands. There are compromised antennas that are much smaller, but they compromise efficiency for size. The list of requirements for HF EMCOM use is the same as for VHF/UHF: Radio Power supply Antenna Frequencies Radio’s that cover the HF bands are generally much more expensive that for the higher bands. For effective use in an emergency situation, you would probably want a radio that can put out up to 100 watts. Lower power, and price, radios exist, but are not as effective. About the lowest buy in for a new HF rig is about $470 for the Alinco DX-SR8T. At the high end, the cost is $3000 -6,000 for something like the Elecraft K3S. The closest thing to “One Radio to Rule Them All” is the Yaesu FT857D, at around $850. This covers almost all of the bands available and is a solid overall radio. Power supplies are pretty much the same as for VHF radios, you just need to take into consideration power use. A 100 watt radio is going to burn through more amp hours of battery quicker than a 40 watt radio. Solar generators are ideal for getting through multiple days without mains power. Antennas can range from simple wire dipoles, to massive beam antennas, to compact magnetic loop antennas. Frequencies will vary between day (usually 20m band) and night (usually 40m) and from event to event. HF requires practice and experience even more than VHF/UHF. There are so many factors that influence communication on these bands that there is almost no way you could be effective without a considerable amount of hands on experience. Conclusion This is a very brief overview that barely scratches the surface of EMCOM and the Amateur Radio / Ham Radio hobby. I hope that this at least gives a good starting point for people who are interested in communications.

  16. [h=1]Oracle Solaris 11 Kernel Source Leaked[/h]December 19th, 2011, 14:00 GMT · By Marius Nestor As Phoronix announced a couple of minutes ago, it appears that a snapshot of the kernel source code for Oracle's Solaris 11 operating system has been leaked on major torrent and file hosting sites. Searching "solaris11.tar.bz2" on Google, Softpedia can also confirm that the bzip2 archive of about 104 MB contains the source code of Oracle Solaris 11's kernel. Being a closed source operating system, Oracle is probably trying right now to delete the leaked Solaris 11 kernel archive from aforementioned sites. The Oracle Corporation announced the Oracle Solaris 11 cloud operating system on November 9th, supporting the security, scalability and performance requirements of cloud-based deployments. Oracle Solaris 11 brings features like the ZFS filesystem, virtualization capabilities, comprehensive management, "secure by default" features, cloud-scale life cycle management, SPARC and x86 certified.

  18. Stack Based Buffer Overflows on x86 (Windows) – Part II In the first part of this article, we discussed about the basics that we need to have in order to properly understand this type of vulnerability. As we went through how the compiling process works, how assembly looks like and how the stack works, we can go further and explore how a Stack Based Buffer Overflow vulnerability can be exploited. Introduction We previously discussed that the stack (during a function call) contains the following (in the below order, where the “local variables” are stored at the “smallest address” and “function parameters” are stored at the highest address): Local variables of the function (for example 20 bytes) Previous EBP value (to create the stack frame, saved with PUSH EBP) Return address (placed on the stack by the CALL instruction) Parameters of the function (placed on the stack using PUSH instructions) Sursa: https://nytrosecurity.com/2017/12/20/stack-based-buffer-overflows-on-x86-windows-part-ii/
