Form-grabbing rootkit sold on underground forums
Posted on 20.05.2013
There seemingly no end to the automated tools that aspiring cyber crooks can buy on underground forums.

The latest of these discovered by Webroot's Dancho Danchev is "Private Grabber", a commercial rootkit that can "grab" any form of communication transmitted over SSL, but is usually mostly aimed at stealing login credentials.

Danchev tested it by grabbing a test username and password for a Microsoft account:


With Ring 3 rootkit functionality, and supporting Windows XP / Vista / 7 / 8, the rootkit can be bought for as little as $75, payable with Liberty Reserve, Western Union, Money Gram or PayPal.

"Potential customers also don’t get a DIY builder, but a bin file that’s individually crypted per customer. Surprisingly, customers will get the updates over email," the researcher shared. "Next to the built-in rootkit functionality, the ‘form grabbing’ rootkit also takes advantage of ‘Smart API hooking', and only hooks the functions responsible of transmitting form related data, making it extremely fast and efficient, according to its author."
