OpenMalleableC2 is a library that replicates Cobalt Strike's Malleable C2 profile format for HTTP transformations. It allows security researchers and red teams to customize C2 communications in their tools, enhancing the ability to disguise callback data in HTTP requests. The project includes a basic example of a "ping pong" agent and server for demonstration.

Nimhawk is an actively developed command and control (C2) framework that builds on the NimPlant project, offering enhanced modularity, security, and a user-friendly web interface for managing implants. Currently, it supports Windows x64 platforms, with plans for a Linux agent in the future. The project encourages community contributions and provides detailed documentation for developers.
