I am looking to spin up a local CTF for my security group that meets monthly and was curious if there is any way to take a retired machine and be able to get a ‘clone’ of it or if I would be able to speak with the creator of the box to replicate it within either a Pi or Mini-PC that would broadcast a WiFi network for the players to connect to and start going at it.
I have worked through a number of boxes but have never set one up personally and would like some guidance if available on how to approach this and any potential hiccups. (Note: Mini-PC will be a bare-metal system, not looking to complicate by virtualizing)
