Avast analyzed a version of Reveton that has a module containing the Pony password stealer, which can also steal virtual currency stored on a computer such as bitcoin. The FBI issued a warning about Reveton in August 2012 after its Internet Crime Complaint Center was flooded with complaints. Reveton is in a class of nasty programs known as “ransomware,” which includes the notorious Cryptolocker program that encrypts a computer’s files. Avast speculated the capabilities may have been added to Reveton due to falling profits.”]
