Abstract
Methods and systems for detecting encrypted bot command and control communication channels are provided. In the exemplary method, the presence of a communication channel between a first network device and a second network device is monitored. Active and inactive periods of the network device are detected and a reverse channel is determined based on the detection. The first network device may then be flagged as potentially infected or suspected based on the reverse channel determination.
