My personal favorite talk was on exploiting Pebble smartwatches ("Exploit Millions of Pebble Smartwatches for Fun and Profit" by Zhang and Wei). Our expectations are usually higher in one's own field of expertise, but this one is really great work. Pebble smartwatch talk at VB 2016 Basically, the authors found an inner assembly routine in Pebble's operating system which allows to elevate one's privileges. If you are familiar with ROP, this is a privilege elevation gadget. Normally, this routine is called by Pebble... [Read More]

VB 2016 Presentation – Oct 5-7, Denver When we first saw and analyzed Locky back in February, we immediately had a hunch that it was the work of seasoned criminals. The tell-tale signs were strong: massive spam runs were used to spread the ransomware, the malware used domain generation algorithm, the HTTP C2 communication was encrypted (the first version, that is), and the ransomware note was multilingual.

Adaptive and comprehensive protection against an evolving threat landscape can be a complex discussion. When you add in layers of marketing hype, footnoted claims, and qualified conditions, then it’s not surprising to hear that customers get confused when it comes to choosing security for their business.

Changes to network... [Read More]

This version has strengthened its self-defense mechanisms by utilizing more anti-debug/anti-VM tricks than its predecessors. It also employs some novel methods for trying to keep its process hidden and running persistently. Moreover, its communication data structure and encryption scheme have changed, rendering the old Andromeda IPS/IDS signatures useless. In... [Read More]

[ This article originally appeared in Virus Bulletin ]( Andromeda is a modular bot. The original bot simply consists of a loader, which downloads modules and updates from its C&C server during execution. The loader has both anti-VM and anti-debug features. It will inject into trusted processes to hide itself and then delete the original bot. The bot hibernates for a long time (from several days to months) between communications with its C&C server. As a result,... [Read More]

[ This article originally appeared in Virus Bulletin ]( The Android/FakeKakao trojan disguises itself as a KakaoTalk security plug-in as a means to lure users to install it.

Moreover, it incorporates anti-debugging and anti-emulator tricks and disables some security software. Unlike other malware, the trojan's DEX (Dalvik... [Read More]
