My notes on an openwrt implant idea: github.com/f0rg-02/Notes/…/openwrt_implant.md

Been trying to build and experiment with simple and cheap devices that could be used as some nice hardware implants. Not very impressive, but it works for what I need/want. The ssh proxy stuff is, so you can run other tools that can’t run directly on the hardware, and running stunnel over it is supposed to help disguise the traffic as ssl/tls. I should note I used a vps in between the implant and the pc with all the proxying and relaying. It was interesting to learn and get working.

I would like to thank the people who took the time to write articles that helped me put this together, mainly these two, which really helped me with the ssh stuff.

The SO that helped me figure out how to do a reverse dynamic ssh proxy on the device: unix.stackexchange.com/a/409535

I need to do a bit more testing before I publish a proper documentation, but everything works finally.
