Stowaway
Multi-hop Proxy Tool for pentesters
...The tool supports active and passive connection modes, making it adaptable to different network layouts. It can route traffic through SOCKS5 and HTTP proxy settings, and it also supports TCP, HTTP-style, and WebSocket-style upstream or downstream transport modes. Stowaway includes encrypted node communication through a shared key, with optional TLS support noted in its runtime parameters. Its feature set makes it useful for studying pivoting, port forwarding, and controlled internal network routing in legitimate test environments.
