Here's a recipe for running the proof of concept using Docker on a Mac:

  cd /tmp
  wget https://github.com/crashappsec/h4x0rchat/blob/9b9d0bd5b2287501335acca35d070985e4f51079/h4x0rchat.c
  docker run --rm -it -v "$PWD:/src" \
    -w /src gcc:13 bash -lc 'gcc -Wall -O2 \
    -o h4x0rchat h4x0rchat.c && ./h4x0rchat'
