Gang operating rogue TOR exit node distributing Windows executables wrapped in malware

Didn't see this article this morning or it would have been in my What I am reading post:

Ars Technica - For a year, gang operating rogue Tor node infected Windows executables -

Three weeks ago, a security researcher uncovered a Tor exit node that added malware to uncompressed Windows executables passing through it. Officials with the privacy service promptly shut down the Russia-based node, but according to new research, the group behind the node had likely been infecting files for more than a year by that time, causing careless users to install a backdoor that gave attackers full control of their systems.

Maybe it's just me but TOR seems less and less to be a helpful privacy tool and more and more like an advanced malware distribution system.
