Recently, when I’m having trouble sleeping, I look for software to fuzz test. Earlier this week, I thought back to Fady Othman’s post “Meta Bug Bounty — Fuzzing ’netconsd’ for fun and profit.” It’s a good tutorial about fuzzing code exhaustively. Like most fuzzing blog posts, I found the work a bit difficult to reproduce because it requires the reader to figure out how to replicate the author’s environment and toolchain.
