Trojan Modifies Firefox to Store Passwords; Infiltrates Protected Storage Area
In a recent blog post, Webroot warned of a Firefox Trojan that forces the browser to save all login credentials by default and subsequently uses the stolen information to create a new user account (username: Maestro) on the compromised machine. It then sniffs out sensitive user data (data forms and login details) from the Windows Protected Storage Area. The data stolen from here is faithfully shipped out to a server once every minute.
The Trojan’s author Salar “Salixem” Zeynali is an Iran-based crimeware hobbyist and heavy metal enthusiast, according to his Facebook profile. With Zeylani choosing his real name above a nom de plume to take credit for the malware, Webroot clearly didn’t have to work too hard to get to him.
“His Facebook profile indicates he lives in Karaj, Iran; He sports an emo haircut, and likes heavy metal music and programming. And, apparently, Zeynali writes crimeware for fun, because he doesn’t sell his keylogger. He offers a keylogger creator tool as a free download from the message board he hangs out on,” Webroot’s Andrew Brandt wrote in the blog post.
“Unfortunately, there are a lot of people who frequent the same message board Zeynali uses to post his keylogger code, and some of those people have clearly been using the keylogger creator tool Zeynali built to create and distribute Trojans.”
