Russian hackers have figured out a way to use Twitter to communicate with malware that’s infected target computers, allowing them to cover their tracks while making their way into confidential government computer systems.

The advantage of this approach is that targeted computer systems don’t register the intrusion. It looks like just another Tweet.
