Tunneling with Chisel and SSF

Having just written up HTB Reddish, pivoting without SSH was at the top of my mind, and I’ve since learned of two programs that enable pivots, Chisel and Secure Socket Funneling (SSF). I learned about Chisel from Ippsec, and you can see his using it to solve Reddish in his video. I wanted to play with it, and figured I’d document what I learned here. I learned about SSF from another HTB user, jkr, who not only introduced me to SSF, but pulled together the examples in this post. [Update 2020-08-10] Chisel now has a built in SOCKS proxy! I also added a cheat sheet since I reference this post too often.
