Techniques for Cobalt Strike Beacon HTTP C2 heuristic detection are disclosed. In some embodiments, a system/process/computer program product for Cobalt Strike Beacon HTTP C2 heuristic detection includes monitoring HyperText Transfer Protocol (HTTP) network traffic at a firewall; prefiltering the monitored HTTP network traffic at the firewall to select a subset of the HTTP network traffic to forward to a cloud security service; determining whether the subset of the HTTP network traffic is associated with Cobalt Strike Beacon HTTP C2 traffic activity based on a plurality of heuristics; and performing an action in response to detecting the Cobalt Strike Beacon HTTP C2 traffic activity.
