    In other news I am leaving VU and its great people to start a new group focused primarily on hardware security. I am hiring motivated PhD students. DM me if you find hardware attacks like or cool and want to actually engineer secure computers! Please RT

    If covid-19 is the Universe's answer to anti-vaxxers, maybe flat-Earthers should reconsider their position. 😬

    My friend, a real biologist, is crowdsourcing a cold/flu/COVID19 dataset. Excitingly, he already has interesting observations. He needs more data. Please fill out his survey if you recently had symptoms, and please tell your friends (and enemies). RT for reach <3

    Have you recently suffered from fever, feeling tired, shortness of breath or other symptoms of cold/flu/COVID-19? Take a a few minutes to turn your experience into potentially useful data! I started this survey:

    Anyone who actually feeds their private github commit key to this code should have their license to open source revoked :-P

    Another day, another embargo and addendum! “New” (not really!) variants of the day: L1D evictions (Fig 6, RIDL paper) or and vector registers or . See . As a bonus: a faster RIDL exploit that leaks a root hash in 4s:

    Long embargos without transparency hurt endusers who remain unknowingly exposed to serious flaws. covers our saga with in her piece. remains a problem after 1+ year, 2 flawed patches and 2 embargos (+1 still ongoing).

    deserves a lot of credit for this. She is better at finding variants than engineers. Also kudos to Jonas Theis, our master student who put together the fast /etc/shadow exploit as a term project!

    Today, last-minute embargo on parts of ends. The "new" is just a variant we reported in Sep 2018, and it leaks your root hashes fast! Latest Intel patches remain broken. See for addendum and exploits.
