The event listing

Cryptography7

Recover a plaintext or a key from something that was supposed to protect it. In practice: identify the scheme, find the parameter the author got wrong, exploit it.

Reverse engineering6

Work out what a compiled program does without its source, then work backwards from the check to the input that passes it.

Misc3

Everything that fits no other box: esolangs, puzzles, scripting exercises, and the jail escapes that have not yet earned their own category.
