Attackers hid a Trojan inside pirated copies of Windows 7 operating system and began circulating them on BitTorrent sites. Damballa reported that it shut down the botnet's command and control server May 10, but by that time infection rates had risen as high as 552 users per hour. "Since the pirated package was released on April 24th, my best guess is that this botnet probably had at least 27,000 successful installs prior to our takedown of its CnC [command and control] on May 10th," said Tripp Cox. In the case of Windows 7 RC, once pirated copies downloaded, attempts to install a bundle of other malware on the infected machine. Blocking infections is tricky, as many anti-virus tools do not yet support Windows 7, reports eWeek.
