Facebook Password Spam Conceals Malware Attack
Researchers at several security firms have uncovered a spam campaign targeting Facebook users. The e-mails, which pose as communications from Facebook about password resets, contain a nasty downloader that ultimately makes users part of a notorious botnet.Researchers at several security firms have tied the Bredolab Trojan to a spam campaign targeting Facebook users. The malware is being blasted out by spammers in e-mails claiming to come from "The Facebook Team." Inside the e-mails is a message that the recipient's Facebook password has been changed. In order to get the new one, recipients are told to open the accompanying attachment containing the malware.
Researchers at Websense told eWEEK Oct. 27 that they have observed more than 350,000 of the messages. On the company's blog, researchers explained that the malware connects to two servers to download additional malicious files. Among them is Pushdo, also known as Cutwail.
%Windir%\temp\wpv861256600826.exe and %Programs%\Startup\isqsys32.exe. Bredolab also creates the processes isqsys32.exe and svchost.exe. Sophos is detecting the malware as Troj/BredoZp-M or Mal/Bredo-A. "Don't make life easy for the hackers hell-bent on infecting your computer, stealing your identity and emptying your bank account - exercise caution when you receive unsolicited emails and protect your computer with up-to-date security software," Graham Cluley, senior technology consultant at Sophos, advised in a blog post.
