We got 9th place at @defcon.bsky.social #CTF! Props to all finalists for an intense fight over the past three days and congrats to MMM for taking the win.
Thanks to Nautilus Institute for the neat setup this year, we had a blast.
Until next time, Vegas!

I am happy to announce that my first paper has been accepted at USENIX Security!
We propose TEEcorrelate, a mitigation that statistically decorrelates reported performance counters from real ones during TEE execution.

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.
