Turning a Regular USB Flash Drive into a USB Rubber Ducky

A long time ago, we reviewed some devices which should be in any hacker's toolbox. One of these devices was a USB Rubber Ducky — a device which resembles a regular USB flash drive. When connected to a computer, it claims to be a keyboard and quickly enters all its commands. It's a pretty cool thing and very useful for pentests, but why pay 40 dollars or more if a regular USB flash drive can be taught the same tricks?

The Children of CryptoLocker, Part 2. TeslaCrypt, TorLocker, TorrentLocker

Previous part: The Children of CryptoLocker, Part 1

The first examples of malware that encrypts files and then demands money for decryption appeared a long time ago. Just remember Trojan.Xorist with its primitive encryption algorithm based on XOR, or Trojan.ArchiveLock written in PureBasic, which used regular WinRAR for encryption and Sysinternals SDelete for deleting encrypted files, and demanded as much as five thousand dollars for decryption. However, it was CryptoLocker that established the bad trend among virus writers to use the latest achievements in cryptography as quite stable encryption algorithms. Today, we will investigate several encryption-based trojans which emerged after the notorious spread of CryptoLocker on the internet (or at the same time).

Injection gloves-off: bypassing antivirus software with Shellter

The great problem for many pentests lies in the fact that any "charged" executable file created with Metasploit or other pentest frameworks can be tracked by any antivirus vendor. That is why a pentester has to find out a way to bypass antivirus software instead of going on with penetration. A lot of time is wasted on this task being performed from case to case. So, eventually, various tools for automation of this task started to appear; today we are going to review one of these cool tools, named Shellter.
