Apply to attend GREPSEC VII! USENIX is hosting the GREPSEC VII workshop (for Ph.D. students in computer security and privacy, focused on mentorship) on August 10-11, 2026 in Baltimore, MD, co-located with USENIX Security '26. Applications are due June 15!

More interposer fun, this time with DDR5 memory. Breaking TDX, SGX, SEV and even Nvidia TEEs. Checkout our work at TEE.fail, and get a personally-signed Intel attestation report at @TEEdotFail.
Check out our demo NOW at CCS 2025! wiretap.fail breaking SGX live at the poster session.
It's easier than you might think!
Want to know what happens when commercial TEEs meet improvised DRAM memory interposers? SGX mayhem including attestation key extraction. Please DO try that at home😉. Check out our work at wiretap.fail/
Embarking on a new project that needs physical access to an H100 GPU. Any chance anyone is willing to let us borrow one (we promise to return it), in exchange for a security exploration into the land of confidential computing? If so, DM me for further details. Thanks :)
Please consider submitting to FC this year! @pedrorechez and I are excited to be chairing, and we need your papers to build a great program!
A great summary of the Zerocash/Zcash origin story. Truly humbled and grateful to have been a part of this, and appreciative of IEEE S&P for the recognition.

The Zerocash paper has won a Test of Time award from @IEEEorg to recognize its substantial, lasting, broad, and currently relevant impact on computer science.
Congrats to my co-authors Eran Tromer, @secparam, Christina Garman, @MadarsV, Allesandro Chiesa, @EliBenSasson for winning a “test of time” award at IEEE S&P for Zerocash!

And the second one is „Zerocash: Decentralized Anonymous Payments from Bitcoin“ (ieeexplore.ieee.org/document…) by @matthew_d_green and others
Congrats to @arushi1250 for successfully defending her PhD today! (My first student!) If you haven't seen it, checkout her great work on improving the security/privacy of Tor with our Bento architecture. Very proud of the work she's done and great things she'll do in the future!

Apply to attend GREPSEC VI! USENIX is hosting the sixth GREPSEC workshop on August 8, 2023 in Anaheim, CA, co-located with USENIX Security '23 and SOUPS 2023. Applications are due May 24: bit.ly/grepsecvi #usesec23 #soups2023 @SOUPSConference
Please apply and join us, in person this year!
GREPSEC workshop for women and underrepresented grad students in S&P is back, live and in person, colocated with #usesec2023! Applications are due May 22, please help us spread the word! usenix.org/conference/grepse…
Excited to finally release the paper we've been working on that explores the challenges of using SGX for real world applications! tl;dr, it's very hard, post-compromise recovery is hard, and we can leak secrets. Also a great resource for learning about SGX attacks and defenses!
Our survey of SGX attacks is out! Come learn about how SGX fails in real life. Check out our website sgx.fail including attacks on @SecretNetwork and @CyberLink PowerDVD.

Excited to announce that registration is open for GREPSEC V -- a workshop for early-stage grad students doing research in security and privacy who come from underrepresented populations. Women/NB/gender minorities, BIPOC, LGBTQ+, etc.

Congratulations!
Huge congratulations to @HexHiveEPFL's @amipri @PurdueCS for passing her defense today. You may know her from fun work on finding unsafe variadic function calls, type safety violations for C++ applications or tightening the bounds for CFI!

Congrats to my student Stephen Herwig for making the paper he led “Achieving Keyless CDNs with Conclaves” reproducible! Conclaves are containers of enclaves, allowing legacy apps (even multi-process with shared memory) to be deployed in secure enclaves. Joint work with @CryptoGPS
USENIX Security still has a few open slots for Lightning Talks! Please signup and help make this already great session even better! There will be prizes...
