Mac OS X Trojan Goes Bitcoin Mining, Steals Files

A new Trojan targeting Mac OS X users is not only after data, but Bitcoins as well.

The malware is being detected by Sophos as Miner-D, but is also known as DevilRobber. According to Sophos, the Trojan is hiding inside pirated versions of the Mac OS X image editing application GraphicConverter version 7.4, and is being actively distributed on file-sharing networks and torrent sites like Pirate Bay. Once on the system, the Trojan creates a backdoor for remote access and installs a Bitcoin miner that uses up any spare CPU or GPU (Graphics Processing Unit) cycles.
“If your Mac computer was infected by the malware, the first thing you might notice is performance becoming sluggish,” Graham Cluley, senior technology consultant at Sophos, wrote in a blog post. “That's because OSX/Miner-D tries to generate Bitcoins, the currency of the anonymous digital cash system, by stealing lots of GPU…time. GPUs are much better than regular CPUs at performing the mathematical calculations required for Bitcoin mining.”

This is far from the first time malware involved in Bitcoin mining has been spotted in the wild. In September, researchers at Trend Micro spotlighted BKDR_BTMINE.MNR targeting Windows users, and in August, Symantec reported detecting the Badminer Trojan targeting Windows as well.
