cs2br-bof
→ View on GitHubCS2BR is a compatibility layer designed to enable the execution of Cobalt Strike (CS) Beacon Object Files (BOFs) in Brute Ratel C4 (BRC4) by translating CS API calls to their BRC4 equivalents. It facilitates the use of existing CS BOFs in the BRC4 environment, though it currently only works at the source code level and does not cover all CS API functionalities. Notable features include a patching process for BOF source code and the option to generate parameters for execution, while users should be aware of limitations regarding certain APIs and the potential for increased code size.
