I recently participated in Samsung’s Hacker’s Playground CTF with Wreck The Line. We finished with 1592 points, in 26th place of 1075 teams. Most of my time was spent on Legonigma, an interesting 500 point challenge based on two renders of a Lego cryptography gadget.

This weekend I participated in ImaginaryCTF 2021 with WreckTheLine. We finished third out of 1018 entrants, the final team to complete all 55 challenges and hit 11330 points, missing second place by 3.5 minutes. Here are my writeups for System Hardening 5 and New Technology.
