Abstract
Techniques for probing for Cobalt Strike TeamServer detection are disclosed. In some embodiments, a system/process/computer program product for probing for Cobalt Strike TeamServer detection includes monitoring HyperText Transfer Protocol (HTTP), HTTPS, and/or Domain Name System (DNS) network traffic at a firewall; prefiltering the monitored HTTP, HTTPS, and/or DNS network traffic at the firewall to select a subset of the HTTP, HTTPS, and/or DNS network traffic to forward to a cloud security service; performing HTTP, HTTPS, and/or DNS probing of a target to detect whether the target is a Cobalt Strike TeamServer; and performing an action in response to detecting that the target is the Cobalt Strike TeamServer.
