We propose TEEcorrelate, a mitigation that statistically decorrelates reported performance counters from real ones during TEE execution.

We find that AMD does ciphertext coherence with cache line granularity, but instead 32 cache lines (half a page)!
And even crazier, it's not 32 adjacent cache lines, but they're spread over a page in varying patterns: each accessed line evicts all others in its half of the page.

I had two NSF grants terminated last week, for a total of just under $1M. The largest one had just started and its goal was to provide users with more context and information on the content that they see on social media.

I'm very happy to announce our new Cohere+Reload: Re-enabling High-Resolution Cache Attacks on AMD SEV-SNP was accepted at DIMVA 2025!

In it @snee.la, @gruss.cc and I investigate AMD's ciphertext coherence mechanism and show even low resolution leakage can go a long way.

โ€˜Climate of fearโ€™: Montreal doctor says NYU cancelled her presentation A Montreal doctor says her presentation at NYU was abruptly cancelled and believes the university did so out of fear of being pressured by the Donald Trump administration.

NYU canceled a planned speech by the former president of Doctors Without Borders because she planned to discuss the humanitarian crisis in Gaza and cuts to US AID.

This is what actual campus censorship looks like.
