I’m M0ud4 — I do vulnerability research and reverse engineering.

Most of my time goes to firmware and embedded targets (IoT routers and cameras), native-code auditing in open-source projects, and reversing whatever looks under-examined. Some of that work has ended up as vendor-confirmed fixes. When I’m not hunting bugs I play CTFs, mostly rev and pwn.

This blog is where I write the parts worth keeping: how a bug was actually found, the dead ends, and the fix.
