DEF CON CTF 2023 Qualifiers

Won this CTF with Blue Water, the collaboration between Water Paddler and Perfect Blue!

I made slides on the two web challenges I worked on:

  • Artifact Bunker, which involves leaking data from a tar archive using partial zip file overwrites.

  • Brinebid, which involves reversing a JavaScript implementation of Python's Pickle serialization to gain remote code execution.
