Ghidra: Reading a Binary Like Source Code

Ghidra is the free, open-source reverse-engineering suite released by the NSA. Its headline feature is a genuinely excellent decompiler that turns compiled machine code back into readable C-like pseudocode — for most challenges it’s the difference between squinting at assembly for an hour and reading the logic in five minutes. It’s the tool I reach for first on any reversing binary, and it’s what cracked Go Go Decompile in the Brunner 2026 set.
