With so much major Supreme Court and legal news dominating the headlines recently, you might have missed an important filing from late June. We joined CDT and OTI to file an amicus brief in CCIA v.

Welcome to day 1 of our NDSS 2026 showcase. We are starting with "Mad Science Hacks." These papers demonstrate attacks that bridge the physical and digital worlds, exploiting physics to break security in ways that feel impossible.

five years ago today, I was hit by a car going 30 mph/50 kph while crossing the street on foot.

It's been quite a journey; one that I could not have done without many of you. I wanted to reflect on just how happy I am to be alive. (cw: vehicular trauma, ortho surgery, hospitals) I was rushing home on 4-Nov-2016, a Friday, after a long pre-election week working at @CenDemTech ... the 2016 Presidential Election was on Tuesday and I was tired and needed to rest for what would probably be a crazy week working on e-voting issues.
