AOC Documentation 2025

46 challenges with 46 published solutions between them. CTFtime has no listing for this event at all, so nothing built on CTFtime can show what it was made of. These writeups were found in public repositories instead. Each link is pinned to the commit it was read from.

Where these writeups live

Uncategorised37

The upstream scoreboard did not say, so neither do we.

Misc4

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

Web2

Reach data or functionality the application meant to keep from you - through its inputs, its tokens, or its trust in the client.

Binary exploitation2

Turn a memory-safety bug in a native binary into control of execution. Usually a stack overflow, a format string, or a heap primitive.

Forensics1

Recover something from a file, a capture, or a disk image - often from a part of it the format says is unused.
