A new generation of botnets abuses popular social media like Twitter, Facebook, and Youtube as Command and Control channel. This challenges the detection of Command and Control traffic, because traditional IDS approaches, based on statistical flow anomalies, protocol anomalies, payload signatures, and server blacklists, do not work in this case. In this paper we introduce a new detection mechanism that measures the causal relationship between network traffic and human activity, like mouse clicks or keyboard strokes. Communication with social media that is not assignably caused by human activity, is classified as anomalous. We explore both theoretically and experimentally this detection mechanism by a case study, with Twitter.com as a Command and Control channel, and demonstrate successful real time detection of botnet Command and Control traffic.
