Announcing #CounterSEVeillance, a novel attack on AMD SEV-SNP inferring control-flow information and operand properties from performance-counter data with single-instruction resolution.
Thanks to @hweissi, Robin Leander Schröder and @lavados for the amazing collaboration!

🚨‼️ New security loophole allows spying on internet users visiting websites and watching videos ‼️🚨
The security loophole known as "SnailLoad" allows bypassing firewalls, VPN connections and browser privacy modes.
No malicious code is required to exploit this vulnerability and the data traffic does not need to be intercepted. All types of end devices and internet connections are affected simply by monitoring fluctuations in the speed of the internet connection.
➡️ tugraz.at/en/tu-graz/service… ⬅️
The research team led by Stefan Gast and Daniel Gruss will present the scientific paper on the loophole at the conferences Black Hat USA 2024 and USENIX Security Symposium.

Our new paper "Generic and Automated Drive-by GPU Cache Attacks from the Browser" has been accepted at @ASIACCS2024! 🎉
We show basic cache attack primitives on NVIDIA&AMD, and more complex attacks on NVIDIA.
You can read it and try a tiny POC here ginerlukas.com/gpuattacks/.

You may have heard about @Intel's horrific #Meltdown bug. But have you watched it in action? When your computer asks you to apply updates this month, don't click "not now." (via spectreattack.com/ & @misc0110)
