Ah, the classic #Usenix #Unix poster, because nothing screams cutting-edge tech like a vintage wall decoration! 🎨✨ On #GitHub, no less, because where else would you want to annotate 'magic' that even your grandpa's computer wouldn't understand? 🖥️🔮 It's a riveting read—if you're a time-traveling developer stuck in the 1980s. ⏳🤖

Our new Android attack, #TapTrap, is getting media coverage. Here's a quick explainer.
It's a new tapjacking technique that exploits Android's UI animations to hijack user taps without requiring any permissions. @beerphilipp will present it at #USENIX Sec'25.
Unlike classic tapjacking, TapTrap uses Android's built-in activity transition animations to launch a transparent activity on top of the attacker's app. The user thinks they're tapping a harmless button, but the tap goes to a permission/system prompt, a browser, or a sensitive app without notice.
It works on Android 15 & 16, while @GrapheneOS has recently issued a fix. Major browsers such as Chrome and Firefox promptly patched after we disclosed the vulnerability. We also analyzed ~100K Play Store apps finding that TapTrap is currently not being exploited in the wild.
This effort is the result of a collaboration with @beerphilipp, Sebastian Roth and @lindorferin. Kudos to Philipp for discovering the issue and doing the heavy lifting. And thanks Vienna Science and Technology Fund (WWTF) for making this research possible and supporting us ♥️
See you at #USENIX in Seattle next month!

Day 2, again lots of great OSDI talks. My favorite was a systematic analysis of sequential performance optimization in practice.

The keynote was pretty good as well, lots of good developer tools coming out of https://github.com/plasma-umass #usenix #osdi25

Busy first day. I was very tempted by the ATC tracks but stuck with OSDI today. My favorite talk was probably Enabling Efficient GPU Communication over Multiple NICs with FuseLink https://www.usenix.org/conference/osdi25/presentation/ren but there were so many good ones…

I am pleased to announce that our second paper got accepted at #USENIX Security 2025!
Two fantastic visiting students conducted the work Tristan Bilot and Baoxiang Jiang at UBC CS with the help of Zefeng Li.

USENIX will discontinue its annual technical conference after the 2025 event

The #USENIX ATC is where I gave my first conference talk, and I have very fond memories of speaking there.
And now they have decided to stop holding them.

🚀🎉 #Nostalgia alert! #USENIX #ATC just caught the Zoom flu 🤧 and decided to RIP itself in 2025. Apparently, "Renaissance-era Florence" 🏰 for #sysadmins couldn't withstand the mighty power of virtual meetups and a couple of nerds on Discord.

Wow, just saw this. #Usenix was a significant driver of my growth as a Unix developer and sys admin. The #SAGE conference in particular was a must-attend for me and me sys admin colleagues. I presented there more than once. I heard my first security paper there. I was there when the original inventor of sudo (whose name escapes me) first presented that soon-to-be universal utility. (The idea was an obvious winner as soon as he described it.)
So many friends from that era. Just a ton of memories (especially from the LISA conferences). And T-shirts.

Really disappointed to learn of the demise of the #USENIX Annual Technical Conference. It was the flagship conference of the USENIX organization and a hub for the dissemination of computing research. I hope USENIX itself is somehow able to continue to thrive. https://lwn.net/Articles/1020306/ #atc #usenixatc

The end of the #Usenix Annual Technical Conference (#ATC):
https://lwn.net/ml/all/CACY3YMGkaDL40r[email protected]/
I attended the 2001 edition in Boston just after my first #OpenBSD hackathon (!c2k1)
At the time they were lending PCMCIA wifi cards to attendees to enjoy the beginning of wireless networking. -

Brown Secure Systems Lab (https://gitlab.com/brown-ssl/) had a strong representation @usenixassociation sponsored events this year! Neophytos Christou presented IvySyn at USENIX Security Symposium (SEC) '23, while Di Jin talked about EPF at USENIX Annual Technical Conference (ATC) '23 earlier in July!
IvySyn fuzzes Deep Learning (DL) frameworks (TensorFlow, PyTorch) for memory-safety bugs and automatically synthesizes Python code snippets for triggering the respective vulnerabilities | https://www.usenix.org/.../usenixse.../presentation/christou | https://gitlab.com/brown-ssl/ivysyn
EPF (ab)uses the (e)BPF interpreter for bypassing various kernel hardening mechanisms in Linux -- we also introduce a set of lightweight defenses against EPF-style attacks | https://www.usenix.org/conference/atc23/presentation/jin | https://gitlab.com/brown-ssl/epf
