Stowaway

Stowaway is a Go-based multi-hop proxy tool created for authorized penetration testing, red-team labs, and security training environments. It uses an admin-and-agent model that allows operators to build a chain of connected nodes across segmented networks. 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.
