Topic: Torrentreactor breach serves potent exploit (rncsys32.exe, Trojan.Botnetlog.11)

[Samker]

Torrentreactor has long been regarded as one of the top bit torrent search engines, and with the demise of The Pirate Bay, it's likely bigger than ever. Now, it's been breached and is serving a potent cocktail of exploits to people browsing the site, Websense Security Labs says.

Attackers have managed to inject an iframe into the site that scours Torrentreactor visitors' computers from a long list of vulnerable applications, including Adobe's Reader and Shockwave programs and Microsoft's Internet Explorer and Office Snapshot Viewer. When it finds one, it downloads and runs a malicious file.

According to Websense, the malware has an extremely low detection rate: http://www.virustotal.com/analisis/0df0d26cbb793ba612236b9750309b3e545fa5339e4da159062abfe6f326b2b7-1246425266 , with just two of 32 anti-virus engines identifying the threat. Once executed, it installs a rootkit on victims' machines.

This isn't the first time that security researchers have reported Torrentreactor is foisting malware on its users. In March 2008, the site suffered a similar iframe attack, according to Dancho Danchev.

The malicious file in the latest compromise communicates with a server at 78.109.29.116, an IP address that web searches suggest has ties to the Russian Business Network. We'll be steering clear of this site for the time being.
