CobaltStrikeScan - Scan Files Or Process Memory For CobaltStrike Beacons And Parse Their Configuration


Scan files or process memory for Cobalt Strike beacons and parse their configuration.

CobaltStrikeScan scans Windows process memory for evidence of DLL injection (classic or reflective injection) and performs a YARA scan on the target process' memory for Cobalt Strike v3 and v4 beacon signatures.

Alternatively, CobaltStrikeScan can perform the same YARA scan on a file supplied by absolute or relative path as a command-line argument.

If a Cobalt Strike beacon is detected in the file or process, the beacon's configuration will be parsed and displayed to the console.


Cloning This Repo

CobaltStrikeScan contains GetInjectedThreads as a submodule. Ensure you use git clone --recursive https://github.com/Apr4h/CobaltStrikeScan.git when cloning CobaltStrikeScan so that the submodule's code is also downloaded/cloned.


Building the Solution

Costura.Fody is configured to embed CobaltStrikeConfigParser.dll and GetInjectedThreads.dll in the compiled ConsoleUI.exe assembly. ConsoleUI.exe should then serve as a static, portable version of CobaltStrikeScan. For this to occur, ensure that the "Active Solution Platform" is set to x64 when building, and that the CobaltStrikeConfigParser and GetInjectedThreads projects are built before the ConsoleUI project is built, so that Costura.Fody can find the required DLLs to be embedded.
