First spotted on Seclists' Full Disclosure Mailing List the rootkit specifically targets Linux kernel version 2.6.32-5-amd64 that is found on 64-bit Debian Squeezy systems and uses "advanced techniques to hide itself," while infecting websites hosted on compromised webservers by injecting malicious iFrames into the HTTP response traffic by directly modifying the TCP packets in a bid to carry out drive-by-downloads on systems used to access sites hosted on compromised HTTP servers. Experts are of the opinion that this rootkit may be the next step in iFrame injecting cyber crime operations, driving traffic to exploit kits.
