Social Media for C&C
Though some malicious software can operate autonomously, many specimens are programmed to stay in touch with the attacker to obtain operating instructions. The mechanism that such bots use for communicating their operators is called command and control (C&C or C2). C&C channels can take the form of IRC chatter, peer-to-peer protocols, generic HTTP traffic, and so on. Several malware samples that appeared recently have also used social media for C&C.
