Much like Ninja Turtles, DroidKungFu now comes in different flavours (5 so far), discovered by Pr. Xuxian Jiang (and research team) and Lookout. If, like me, you are having difficulties keeping track of those variants, this post is for you :) The similarities and differences between all 5 variants are depicted below. The various blocks represent each variant, and their intersection shows how many methods they share exactly*. All variants share the same malicious commands (CMD box). They can download and install new package, start a program (called... [Read More]

This concludes my overview of VB2011, with the final notes for the last tasks I attended. Enhancing filtering proactivity with reverse IP and reverse whois queries - Claudiu Musat (presenting) and Alin Octavian Damian The most typical methods to filter spam is by URLs they contain or domain names.

There are other methods, which seem more proactive: reverse... [Read More]

A second life in a virtual environment: from simple socialization to revealing sensitive information - Sabina Raluca Datcu ** Sabina conducted a study on how much security-aware people are likely to reveal on social networks. To do so, she took 50 people from a hacking community, and 50 from the IT security world, and built a fake female profile in both cases with similar interests. She shows that she makes contact with all 100 people over time, and that over time, all 100 people do reveal some personal information to her. Personal information... [Read More]

Missed those talks at VB2011? A few notes on a first set of talks I attended. A look at the cybercrime ecosystem and the way it works, Dmitry Bestuzhev On the underground market, it is possible to find plenty of things such as clones of real ID documents (shipping with your own picture) and even with real biometric information. You can also find real policeman cards. To access the undergroutnd market, you should however be a 'certified' cybercriminal. There are geographic differences between cybercriminals. In Europe, cybercriminals make quite... [Read More]

EASE stands for Experimental ActionScript Emulator, and besides being a pun of debatable quality, it is the in-house tool we at FortiGuard use to analyse malicious Flash samples, unpack obfuscated code (if applicable), and automatically detect heap spraying and JIT spraying (two techniques essential to bypass DEP/ASLR when exploiting a vulnerability). Adobe Flash being nearly ubiquitous today, this is quite a useful tool for analysts and security researchers alike. Now for the bad news, which actually lays in its very name: It's experimental....

QR code with a link to Riskware/Jifake!Android A long time ago, more than 2 years ago actually, I blogged about the dangers of QR codes: "virus gangs could use this technology to have the end-user follow malicious links or send messages to premium numbers" and, this is exactly what happened a few days ago, when Denis Maslennikov found a QR code leading to a mobile malware, named Jifake, that sends SMS messages to a premium number. I told you so, and I couldn't resist telling you ;) QR codes are very handy, but they're an incredible vector... [Read More]
