Lockpicking in CTFs (WHY2025)

The WHY2025 Capture the Flag competition (CTF) has multiple lockpicking challenges as part of the CTF. Successfully picking these locks gives you one of the flags. To be able to create a solid CTF challenge out of an ordinary lock we had to come up with some kind of solution. We used our past experiences in CTFs as inspiration to see how we could do it better. This talk shows the concepts we came up with and which are currently used in the WHY2025 CTF.
