We show that AMD's Quality of Service features can amplify side channels in confidential computing. A malicious hypervisor can use QoS allocation/monitoring to leak/boost activity and enable keystroke detection, website fingerprinting, Bleichenbacher (RSA) attacks, and covert channels in SEV-SNP.

You did it! 🥳 European Parliament just decided that Chat Control 1.0 must stop. This means on April 6, 2026, Gmail, LinkedIn, Microsoft and other Big Techs must stop scanning your private messages in the EU. #PrivacyWins 💪

🚨No Joke: Conservatives in the EU Parliament (EVP) want the vote on #ChatControl 1.0 to be repeated this Thursday - even though the Parliament already voted NO! 😡 Make sure your MP stays strong. Contact them now! 👉 fightchatcontrol.eu#contact-tool

I'm looking forward to presenting my paper, "Continuous User Behavior Monitoring using DNS Cache Timing Attacks" at NDSS next week! We mount an Evict+Reload-style attack on the local DNS cache, detecting recently accessed domains and evicting to continuously monitor new accesses.

vibecoded web apps have such boring security bugs. "the whole database was wide open". oh. ok. at least have some class and write some sql-injectable php. maybe a little stack buffer overflow as a treat.

In the paper, we revive practical attacks on the Linux page cache and provide a systematic classification & understanding of primitives interacting with page cache. This understanding helps us advance page cache attacks, including speeding up previously known mechanisms by six orders of magnitude.

OK, this is wild. In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them. It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*. What the HELL? 1/
