A lot of people are missing (I will try to add more as I find them) but make sure you follow people already in the list!

Compromising OpenWrt Supply Chain via Truncated SHA-256 Collision and Command Injection Introduction Hello, I’m RyotaK (@ryotkak ), a security engineer at Flatt Security Inc. A few days ago, I was upgrading my home lab network, and I decided to upgrade the OpenWrt on my router.1 After ac...

This is really great research by @ryotak.net -

I appreciated that he covered some of his experiments along the way, and how he landed on a finely tuned way of finding a 12-char hash collision with a command injection payload at the end.

Hey, depending on the scale of your organisation, you may be able to manage with some open source tooling, but maintaining this system, speed, reliability and scale, as well as gaining unique security research based on your attack surface will be difficult. Feel free to DM if you want to chat more.
