krypton-c2-stub
Collab Security Research C++ / Python
Lightweight modular research C2 transport agent with encrypted WebSocket heartbeat and in-memory payload execution.
Overview (English)
krypton-c2-stub is an offensive security research project exploring stealthy, resilient Command & Control communications. The client stub is written in native C++ with zero external dependencies, designed for direct memory execution, while the staging backend server is authored in async Python. Built strictly for authorized red teaming and defensive telemetry analysis.
Key Capabilities
✓ Encrypted WebSocket Transport
AES-256-GCM encrypted bi-directional heartbeat masquerading as legitimate TLS traffic.
✓ Reflective Memory Loader
Executes auxiliary modules directly in memory without writing binaries to the file system.
✓ Jitter & Anti-Beaconing
Randomized check-in intervals and payload chunking to defeat heuristic behavioral sensors.
✓ Cross-Platform Server Daemon
High-concurrency async Python server daemon supporting operator session multiplexing.
