Torrented Windows 7 RC Helps to Build Botnet

Maximum PC Staff

Bit Torrent user’s who scored pre-released versions of the Windows 7 RC may have gotten more then they bargained for. Malware-laced copies of Microsoft’s newest OS were seeded to torrents in late April, and security researchers are warning users who may have downloaded Windows 7 from non-Microsoft sources, to format, and reinstall their OS.

Adoption rate of the pirated version has slowed since the official release, but as many as 27,000 machines were estimated to be compromised when the command and control center for the bot net was located and finally shut down on May 10th by authorities. Currently, researchers at Damballa are monitoring installations of the infected version, and estimate that approximately 1,600 new machines are added per day. The good news here is that new installations won’t be drafted into the bot net, but it’s still not a good idea to run software from non-trusted sources.

Blocking this type of infection is difficult researchers confess since the Trojan was integrated into the OS installer, and it became active immediately following setup. The situation is also compounded by the reality that Windows 7 still has very limited anti virus options. Operating systems however aren’t the only attack vector for those looking to poison torrents. Similar malware infested Trojans were found in other popular torrented applications including iWork 09 and even Photoshop CS4.

I guess you really do get what you pay for.
