Excited to share my latest blog post: "Breaking Control Flow Flattening: A Deep Technical Analysis" I showcase usage of formal proofs and graph theory to automate CFF deobfuscation, among other things ! Might make it a talk...? 👀 zerotistic.blog/posts/cff-remo…

Valorant is winning the war against PC gaming cheaters. I've interviewed Riot Games' head of anti-cheat and it's clear that the investment into its Vanguard system is really paying off. Full interview below 👇 theverge.com/2024/11/4/2428…

(1) Decided to release the source code for my LLVM-based static binary analysis framework (github.com/Colton1skees/D…). It implements, among other things, an iterative control flow graph reconstruction algorithm heavily inspired by SATURN, using Remill and Souper.

This strange tweet got >25k retweets. The author sounds confident, and he uses lots of hex and jargon. There are red flags though... like what's up with the DEI stuff, and who says "stack trace dump"? Let's take a closer look... 🧵1/n

I just published the long-awaited Part 2 to my PCIe blog post series - "All About Memory: MMIO, DMA, TLPs, and more!" This post also includes a companion experiment where I dive into what pcileech looks like over a PCIe protocol analyzer. Please enjoy! ctf.re/kernel/pcie/tu…


It's been a while. I open-sourced a project that obfuscates control flow using MBA, all done by your compiler at compile-time using a header-only library. github.com/ThatLing/limba

Today we've published Intel Microcode decryptor! It gives you an amazing opportunity for researching x86 platforms. You can understand how Intel mitigated spectre vulnerability, explore the implementation of Intel TXT, SGX,VT-x technologies! Enjoy it! github.com/chip-red-pill/…

In other news, I've recently put together a big state of the art regarding symbolic execution techniques used in system research. Check out the slides here! 1/2 docs.google.com/presentation/d…

I'm still looking for a few people to join our team. We would prefer people in Belgium but remote from anywhere in the EU is fine as well. Just DM me!

Do you have experience in IoT hacking? Reverse engineer firmware or malware? Security code review? Did You identify vulnerabilities in consumer electronic devices? Just contact me. We are looking for people to reinforce our team at Sony ! @aris_ada @_bajk @mtrojnar @KKKas_

I wrote some stuff about how game package managers (e.g., Steam, Origin, etc.) handle game installations. It's a nightmare and full of compromises specially for old games. parsiya.net/blog/2022-02-0…

Great article by @bryanmenegus talking about the current state of anti-cheating (feat. quotes from some of your favorite peeps): wired.com/story/kernel-a… Glad to see this article come out 👏

A few months ago Cellebrite announced that they would begin parsing data from Signal in their extraction tools. It seems they're not doing that very carefully. Exploiting vulnerabilities in Cellebrite's software, from an app's perspective: signal.org/blog/cellebrit…
