On Tuesday at around 04:20 a.m. Pacific time, bittorent.com and utorrent.com were both hacked by an unknown intruder. The hacker(s) tampered with the downloads so that upon downloading a file, the user would be infected with rogueware. If you don’t already know, rogueware is that annoying piece of Malware that pretends you are infected with a virus and forces you to pay for it to be removed.
The rogueware is called Security Shield and a bittorent official noted ”We have completed preliminary testing of the malware. Upon installation, a program called ‘Security Shield” launches and pops up warnings that a virus has been detected. It then prompts a user for payment to remove the virus. ”
The website was only infected between 4:20 a.m. and 6:10 a.m. Pacific time. If you downloaded software within that hour and fifty minutes window then it is likely that you are infected. If not, you should be clean.
