A simple collection of CTF challenges for the raspberry pi.
Clone this repo on a raspberry pi. Create a very low priv ctf user account. To try each level create a flag.h file in the respective folder, and compile with the build.sh script. Run the bash script to start it up as root so that it can su to the ctf user.
Older versions of the raspberry images have -no-pie as a standard compiler flag, whereas newer ones have -pie as the standard. If level3 doesn't seem to work out for you compile it with -no-pie, similiarly level4 is intended to be compiled with -pie
