NorthSec 2023

NorthSec 2023 happened May 19-21 in Montreal, Canada. There were 76 teams of 8 people each, so the competition was fierce.

I competed with cold_root, and spent most of the time working on hardware reverse engineering challenges, so these write-ups will cover those.

Challenges I attempted:

• Candy Machine
• Reversing the Xtensa ESP32
• Practice Math!
• Badge LED Challenge 1
• Badge LED Challenge 2
• Badge LED Challenge 3
• Badge LED Challenge Bonus
