Chisel

What it does

Chisel is a fast TCP/UDP tunnel transported over HTTP and secured via SSH, used to pivot through firewalls and NAT. It's a common choice for port-forwarding during post-exploitation.

Common use cases

• •Tunnel RDP or SSH traffic through a restrictive firewall using HTTP-encapsulated proxy.
• •Reverse port forwarding from a compromised host to expose internal services to the attacker.
• •Establish persistent SOCKS proxy through NAT for lateral network scanning from outside.

Key features

• •Single binary for client and server — no installation or runtime dependencies.
• •Tunnels TCP, UDP, and SOCKS5 traffic over HTTP with optional SSH encryption.
• •Supports both forward and reverse proxying for flexible network-pivot scenarios.
• •Built-in web interface for monitoring active tunnels and connection status.
