Carders.cc, a German online forum dedicated to helping criminals trade and sell financial data stolen through hacking, has itself been hacked. The once-guarded contents of its servers are now being traded on public file-sharing networks, leading to the exposure of potentially identifying information on the forum’s users as well as countless passwords and credit card accounts swiped from unsuspecting victims.
The breach involves at least three separate files being traded on Rapidshare.com: The largest is a database file containing what appear to be all of the communications among nearly 5,000 Carders.cc forum members, including the contents of private, one-to-one messages that subscribers to these forums typically use to negotiate the sale of stolen goods. Another file includes the user names, e-mail addresses and in many cases the passwords of Carder.cc forum users.
A third file — which includes what appear to be Internet addresses assigned to the various Carders.cc users when those users first signed up as members — also features a breezy explanation of how the forum was compromised. The top portion of this file — which is accompanied by an ASCII art picture of a cat — includes an oblique reference to the party apparently responsible for the Carders.cc site compromise, noting that the file is the inaugural issue of Owned and Exposed, no doubt the first of many such “e-zines” to come from this group.
