简介
Current techniques to monitor botnets towards disruption or takedown are likely to result in inaccurate data gathered about the botnet or be detected by C&C orchestrators. Seeking a covert and scalable solution, we look to an evolving pattern in modern malware that integrates standardized over-permissioned protocols, exposing privileged access to C&C servers. We implement techniques to detect and exploit these protocols from over-permissioned bots toward covert C&C server monitoring. Our empirical study of 200k malware captured since 2006 revealed 62,202 over-permissioned bots (nearly 1 in 3) and 443,905 C&C monitoring capabilities, with a steady increase of over-permissioned protocol use over the last 15 years. Due to their ubiquity, we conclude that even though over-permissioned protocols allow for C&C server infiltration, the efficiency and ease of use they provide continue to make them prevalent …
