New subscription-based ‘stealth Bitcoin miner’ spotted in the wild
By Dancho Danchev
Bitcoin, the digital peer-to-peer based currency, is an attractive target for cybercriminals, who persistently look for new monetization tactics to apply to their massive, but easily generated botnets. Not surprisingly, thanks to the buzz surrounding it, fraudulent Internet actors have begun to look for efficient ways to take advantage of the momentum. A logical question emerges – how are market oriented cybercriminals capitalizing on the digital currency?
Instead of having to personally infect tens of thousands of hosts, some take advantage of basic pricing schemes such subscription-based pricing, and have others do all the infecting, with them securing a decent revenue stream based on a monthly subscription model.
Let’s profile the international underground market proposition, detailing the commercial availability of a stealth Bitcoin miner, feature screenshots of the actual DIY miner generating tool, screenshots provided by happy customers, and perhaps most importantly, MD5s of known miner modifications ‘pushed’ since its first commercial release.

A diversified international underground market proposition? Check. A novel approach to monetize malware-infected hosts? Not at all. Let’s profile the actual market proposition, and discuss in-depth why its model is flawed by design.
