🔥 1/ In the last 6 months working on Linux kernel bug hunting/exploitation there has been a number of key resources which have been super useful (coming from a macOS/Windows background) to understand the state of things in 2022 🚀. Here's a short🧵 to recognise this + thoughts:

@steven_rossi_ and I taught a course on Binary Exploitation and Vulnerability Analysis at UMass Amherst for the past 2 years. After this semester's offering we decided to open source all course material including lecture vods, slides, and projects. pwn.umasscybersec.org

Getting a lot of DMs about how to start in the Web3 security space I’ve seen a few threads about this and honestly, they are all good, but This is what I did personally:👇
Breaking JIT range assumptions in JSC: here's my writeup for b3typer from bi0sCTF 2022! blog.bi0s.in/2023/01/23/Pwn…

Now this is creepy. This AI model can detect the pose of people in the room based just on WiFi signals. No camera needed.
From 0 to 38 audits 🕵🏻♂️ In July, I quit my web2 dev job. I spent August grinding past CTFs to prepare for @paradigm_ctf Then was the Paradigm CTF, and that was the biggest charge of motivation I had ever had. In September I did my first security audit, and here I'm now 👇
Late christmas present: github.com/TheOfficialFlo… WebKit+Kernel exploit chain for all PS Vita firmwares. This is a WIP from 3 years ago that I never finished (exploit is fully working, but hasn't been turned into a jailbreak yet).
pretty good collection of exploitation-friendly linux kernel structs: blog.csdn.net/panhewu9919/ar… also recommend browsing the kCTF cook book: docs.google.com/document/d/1a9…
The Christmas open-obfuscator challenge is live at this address: obfuscator.re/challenges/ Thank you to @vector35 @build38dotcom and @eshard for sponsoring the prizes of this challenge.
I had some #flareon9 writeups i forgot to share: matth.dmz42.org/posts/2022/fla… but nothing revolutionary :-)
ITS FINALLY DONE Twas the night before an upgrade ⭐️🎄❤️
