Excited to present "Going Beyond the Limits of SFI: Flexible and Secure Hardware-Assisted In-Process Isolation with HFI" at ASPLOS, with Tal Garfinkel Kazem Taram Joey Rudek Daniel Moghimi Evan Johnson Chris Fallin Anjo Vahldiek-Oberwagner Michael LeMay Ravi Sahita Dean Tullsen Deian Stefan (1/6)

Today, we lost a visionary. Gordon Moore, thank you for everything.

This is exciting! Congrats to the team!

Congrats to #PurdueCS Professor Kazem Taram and fellow authors for the Distinguished Paper Award at ASPLOS 23. 🏅Going Beyond the Limits of SFI: Flexible Hardware-Assisted In-Process Isolation with HFI ➡️doi.org/10.1145/358201…

Do you want to know the structure of Intel’s cond branch predictors? Attend Hosein’s talk IEEE S&P Tue 9 am, sw sec session, or see the paper t.ly/zKTjw It was so much fun working on this as we encountered so many surprises! UCSD CSE Purdue Computer Science

The HPCA 2024 main track submissions website is open! Abstracts July 28, papers August 4. Please RT. hpca2024.hotcrp.com

Extremely honored to receive the inaugural SIGMICRO dissertation award! Huge thanks to my PhD advisor, Dean Tullsen (of UCSD CSE), my mentors, collaborators, and support network!

At the forefront of innovation, Purdue University is achieving excellence at scale with Purdue Computes. Purdue Computer Science and PurdueECE are hiring TT assistant and associate professors in all areas. ➡️ purduecs.info/40uDJOR #PurdueComputes #AcademicJobs #FacultyRecruiting

I've created a webpage for tracking deadlines for Computer Architecture and Security Conferences. Here's the link: deadlines.cpusec.org. Feel free to contribute by sending pull requests to github.com/hoseinyavarzad…. #computer_architecture #computer_security

Do you remember Spectre that has crumbled OS and software maintainers for years? HOSEIN. YAVARZADEH did some crazy reverse engineering of branch predictors in Intel CPUs & turned out Spectre has a much broader attack surface than people originally assumed. Attacks only get better... 👇

Pathfinder can leak almost entire control flow of almost any program!! You can also perform Spectre with highest precision by individually mistraining any single iteration of a looped branch. Proud of HOSEIN. YAVARZADEH for his amazing job leading this work! Purdue Computer Science

🚨 Branch Target Injection (Spectre v2) attacks are back, now with ultra-high precision! 🚨 Introducing our new paper, "Indirector," where we unveil the intricate details of the Indirect Branch Predictor (IBP) and the Branch Target Buffer (BTB) in high-end Intel CPUs. #security

📢Anyone who talked to me in the past year heard my rant of *LLM memorization is beyond form* & output overlap! ©️Reproducing similar series of events, or character traits also has copyright issues. 👩‍⚖️In new work we look at non-literal copying in LLMs! arxiv.org/abs/2407.07087

I wrote a piece on SIGARCH blog about the state of hardware and architecture security. "Secure Computer Architecture in the Post-Meltdown World: A Long Road Ahead" sigarch.org/secure-compute…

It’s the season of “finding ur next adventure” and folks have been asking me about my experience doing a postdoc, so I did a blog post/video w/ Sasha Rush 's help! Should I do a postdoc? What is a postdoc anyway? youtu.be/O7psT1ftwqs Blog: homes.cs.washington.edu/~niloofar/blog…

Got some negative or unrealistic threat model results that still bring interesting insights? A side channel that requires root to leak something from the kernel? Reproducing prior work? Somewhat related to microarchitecture? Here's your venue: uasc.cc

So proud of my student, Berk, for presenting his first paper at asplos which also won the best paper award!! Congrats to the team! Can we have interrupts that are as fast as polling for fast IO/preemption so we don’t have to burn cores? paper: tinyurl.com/msw6cubh Purdue Computer Science

RT appreciated! We're assembling the Artifact Evaluation Committee (AEC) for USENIX Association OSDI+ATC 2025. JOIN US! It'll be fun, useful (help understand research artifacts of accepted papers), with a manageable load (1-2 papers per AEC member based on research interests).

#PurdueCS researchers developed a faster way for CPUs to handle tasks—no wasteful polling. Their extended interrupt (xUI) system reduces overhead + saves energy. 🏆 Best Paper at #ASPLOS2025 🔗 purduesci.com/4jpDBbm Led by Berk Aydogmus, Kazem Taram w/ UC San Diego collaborators.

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 :)
