The FBI last week issued a warning that the number of Reveton infections has recently been surging. Some versions of the malware pretend to be from the FBI, while others list the Department of Justice’s Computer Crime and Intellectual Property Section as being behind the freeze. Reveton is typically delivered via the Citadel Trojan malware, according to the FBI’s warning. The malware debuted on Russian underground hacking websites in December 2011 and sells for $2,500. The developer has announced that he’s withdrawing the malware from the open–albeit underground–market.”]
