CTF Writeup: Autorev 1 — picoCTF
The article discusses a CTF challenge called Autorev 1 from picoCTF, which focuses on automated binary analysis. Participants must extract a hardcoded integer from 20 unique ELF binaries within a one-second timeframe for each. The challenge emphasizes the importance of scripting in reverse engineering rather than manual analysis.
- ▪The challenge tests the ability to automate analysis at scale.
- ▪Participants receive 20 unique ELF binaries as raw hex-encoded byte streams.
- ▪Each binary contains a hardcoded 'secret' integer that must be extracted within one second.
