The profiles available on GitHub are more aimed at testing your detection capability of different APTs and CrimeWare C2s seen in the wild in the past. However, these have also been fingerprinted, and will also generate a detection. There are Malleable profiles available on GitHub which can be used and these will change your C2 settings from the default. Like with any exploitation tool, if you use the default values it’s likely you’ll be detected. For HTTPS connections, detections occur on the certificate used for encryption. HTTP Beacons are easily detectable, due to the payload being unencrypted. You have a choice of different protocols for your C2 with HTTP, HTTPS and DNS being three popular ones. In Cobalt Strike, Malleable profiles are used to define settings for the C2. These detections are basically looking for specific patterns in network packets.įor popular tools like Cobalt Strike the basic “out-of-the-box” settings for Beacons are fingerprinted by vendors, and therefore going to be detected. Additionally IDS and IPS also have basic detections for C2 traffic. Many AV products like Symantec Endpoint Protection (SEP) have network detection capabilities that monitor traffic passing through a device’s network interface. In this mini-post, we’re going to look at how to easily bypass network detections for Cobalt Strike beacons.
