The event listing

Uncategorised7

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

Binary exploitation5

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

Web4

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

Misc4

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

Reverse engineering2

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