Montrehack - ROP101

This repository contains the source code, binaries and solutions to the Montrehack workshop held on February 20th, 2019.

The workshop was live streamed and you can find my presentation of the slides as well my walk through of solutions 1 and 2 on Twitch.

Running

For the challenges: have docker installed, run ./dist.sh. The challenges will be exposed on localhsot, port 3001 to 3003.

For the solutions: With pwntools installed, edit sols/N.py to point to your local process or to the remote address, and run the script. To follow along in GDB, you can use gdb.debug() and run the script while running in tmux or screen.

Cleanup

docker stop rop-final
docker rm rop-final
docker rmi rop-final

Compiling

If you build the challenges yourself, remember that offsets may change and the solutiosn will no longer work. Using the challenges in bin/ will give the better experience. The code is provided to help understand why/how the challenges work.
