If @AMD knows how to get Strix Halo from 4W idle down to 0.5W (what Apple M series is), we'll seriously think about it.
After Months of Development, FINALLY ready to share: Harden System Security🎉 ✅ Complete System Hardening ✅ Security Posture Analysis ✅ All-in-One Toolkit ✅ Built-in Intune support for Scalability ✅ Beautiful Modern UI ✅ CLI support github.com/HotCakeX/Harde… #Cyber #Windows
rust evasion capabilities are mostly just a byproduct of current tooling lag. static analysis tools struggle with rust's memory model right now, but that's temporary. the real trade-off is managing binary bloat; unless you go no_std, that massive signature is pretty loud on disk.
Single core perf on arm is crazy good, I'm doing most of my daw stuff on arm these days

This week I had the pleasure of guest lecturing at both Georgetown University and Johns Hopkins SAIS on the intersection of AI, cyber and national security. You can find a brief overview of the topics I covered and my slides here. secure.dev/ai_cyber_natse…
🚨 NEW PAPER 🚨: “From Chaos to Capability: Building the U.S. Market for Offensive Cyber” by myself and @SergeyBratus 👉 ists.dartmouth.edu/programs/publi… Should the U.S. outsource its cyberattacks? We talked to 30 experts across gov, VC, and industry to find out.
Hardest Arsenal photo of the year
Hard mode.
Hacking the same target at p2o 5 years in a row. This is the first time I never acquired or tested on the physical device. 1 bug. No ROP, no hard coded offsets. Screenshot is very satisfying. HUGE thanks to @boredpentester for helping with firmware.
I think it’s very strange that encrypted chat has become accepted as a norm but people still call plain text when FaceTime and signal calls are simple. No more plaintext 🚫 satcom.sysnet.ucsd.edu/docs/dontlooku…
New blog on WIndows agent security - blogs.windows.com/windowsexperie…
8xAMD MI300X mostly out of the box on nanochat (which is really an amazing repo and I'm excited for my custom chatbot). This is without PYTORCH_TUNABLEOP_ENABLED which I was too impatient for.
💣 We caught @ycombinator–backed @gecko_sec stealing two of our CVEs, one on @ollama , one on @Gradio. They copied our PoCs, claimed CVE IDs, and even back-dated their blog posts. Here’s the full story 👇
Interesting... "The results were striking: over 65% of data breaches could have been prevented with just three security invariants." 1. Hardware second factors 2. Egress control 3. Positive execution control securityblueprints.io/posts/three-se…
Big to see Call of Duty and Battlefield launching with strong security requirements for anti-cheat. I've been saying this for years!! IMO @riotgames deserves a lot of credit here for setting the right trend.
Activision will require 'Call of Duty: Black Ops 7' players to use TPM 2.0 and enable Windows Secure Boot as part of its anti-cheat initiative. tomshardware.com/video-games/pc…
Exciting news, tech fam! Microsoft just dropped Patina—a Rust-powered, open-source UEFI firmware to boost boot security! Say goodbye to old bugs and hello to safer, faster devices. Check it out: github.com/openDevicePart… #Cybersecurity #Rust #Microsoft
Microsoft just open sourced a Rust implementation of UEFI boot firmware called "Patina" this is a MASSIVE step forward in improving boot security for all. Exciting!!! github.com/openDevicePart…
