The latest InfraTrust Pulse is out and September’s data reminds us that CVSS alone isn’t a patch strategy. Reachability, active exploitation, device role, inherited components, and firmware exposure all matter when deciding what gets attention first. na2.hubs.ly/H07-9WC0
Hardware is the new cloud… oh wait
Before AI: - hardware is hard - teams > solo founders - technical founders only - PhDs build tech in search of a problem - hot SaaS startups get 100x ARR multiples After AI: - hardware is the only thing AI can't build - solo founders are 100x engineers - anyone can build - PhDs
Agents taking over GPUs, BMCs, DPUs in the data centers and we are in for a rough ride…
Neoclouds have limited cybersecurity. Next time agents successfully go rouge, they'll try taking over a neocloud to run more copies. This is bad. Thus: neoclouds should greatly strengthen their cybersecurity and every company with strong cyber models should help with that.
agents will find & repurpose attack surfaces humans overlook ie. Artifactory in @OpenAI - @huggingface incident Neoclouds have an even less visible hardware layer: firmware, BMCs, GPUs and network devices. @eclypsium already protects some of the largest neoclouds.. but so many still fly blind cc @c7zero

This is beautiful. DRAM scrambling + C6 save state
New exploit: “xor dword [0xf80c2094], 1<<22” Unlocks CPU microcode, the platform security processor, system management mode, and every internal processor register, all at once, on 100 million AMD CPUs. As far as I can tell can’t be fixed. github.com/xoreaxeaxeax/s…
"Peter Thiel says, you have to be contrarian but right to be an entrepreneur. So, you have to be comfortable looking stupid for a long time. When I was calling those banks and saying, "Hey, we're a crypto company. We want to do this," they would hang up on me. Or I'd go pitch the 30th venture investor and get a no. Or the thousandth employee we tried to hire or whatever. We're willing to be misunderstood for a long time. And then you slowly start to have these breakthroughs. If you look at Uber, they were fighting for a decade to just be like, yeah, it's actually better and safer than a cab — and the entrenched interests were fighting them. Or Airbnb with the hotels. Self-driving cars. Everything that's truly innovative and breakthrough is going to upset an entrenched incumbent, eventually intersect with the government, and just piss off some segment of the population who are like... "How dare you question the status quo." — @brian_armstrong

I've got some really cool gift recently... UEFI Petya PoC: youtube.com/watch?v=dMOiyp… 😁
The BadCAM research has been published! Why is this significant? Attackers can now weaponize connected USB peripherals that run Linux and do not validate firmware signatures.
If you use llamafile, llama.cpp, llama-cpp-python, Oobabooga, LMStudio or any other software that exposes llama.cpp grammar sampling, I found a few remotely exploitable bugs triggered through a single web request that got patched today. More to come from my work at @Eclypsium
found a critical bug that exists in every Linux boot loader signed in the past decade 🥰 github.com/rhboot/shim/co…
Found my first UEFI vulnerability (signed bootloader OOB-W) 😊
Added #downfall detection via content update
A recent update to the Eclypsium platform allows customers to detect one of the latest hardware attacks against Intel processors dubbed "Downfall." Downfall allows attackers to steal data from other processes, such as cryptographic keys. Fixes are available for certain platforms.
I found a remote(-ish) memory corruption bug in Intel's BIOS. Bluetooth HID Report parsing is yucky research.nccgroup.com/2023/08/08/int…
Hundreds of models of Gigabyte motherboards, used in gaming and other high-performance computers, have a backdoor in their firmware that invisibly downloads code to the machine at startup—and does so insecurely, leaving the feature open to abuse. wired.com/story/gigabyte…
Eclypsium analysis found a backdoor in Gigabyte systems implementing intentional functionality during system startup. Due to significant #supplychainrisk, we're disclosing this info & defensive strategies on an accelerated timeline >> bit.ly/3N6axIA #supplychainsecurity
ShadowHammer campaign all over again but with MSI now
Attention anyone having an MSI motherboard or computer. MSI just said they were hacked and attackers might have tried modifying BIOS and software updates. Disable all updates from MSI for the time being pcmag.com/news/msi-confi…
Such a loss :(
It is with profound sadness that we mourn the loss of our friend and mentor, @aloria. Kelly had an indomitable spirit, and our world is a bit darker without her.
New release: #TinyTracer v2.3 : github.com/hasherezade/ti… - with improved syscalls tracing support - now syscalls are automatically mapped to corresponding functions names
