How Hackers Hid a Money-Mining Botnet in the Clouds of Amazon and Others
"One of their first experiments with their new cloud-based botnet was mining the cryptocurrency Litecoin.

Putting their entire botnet behind that effort would have generated $1,750 a week. “And it’s all on someone else’s electricity bill,” says Ragan."
