BlackHoodie 2018 Workshop

Capture The Flag - An Introduction To Binary Exploitation

Slides and challenges for my binary exploitation workshop at BlackHoodie 2018.

Note: The challenges are no longer running on ctf.katharina-maennle.de. See the following instructions to set up your own environment.

Challenge Setup

To recreate the CTF environment with docker:

./docker_build.sh <module_name>
./docker_run.sh <module_name> <port>

module_names: {chall0, chall1, chall1c, chall1d}

Connect to the service:

nc localhost <port>

Use the following command to retrieve the libc used in the docker environment:

docker cp chall1:/lib/x86_64-linux-gnu/libc-2.27.so .
