As VUSec is one of the places that found some of the early "named/logo bugs" for microarchitectural attacks, I liked that they had an emulation cabinet with a "LOGO INVADERS" design on it :)

And I got to meet #OST2 instructor Sina Karvandi (of HyperDbg fame -> ost2.fyi/Dbg3301) in person for the first time, as he's doing a PhD there.

(And I promise I learned my lesson that next time I teach the in-person workshop I will make sure to upgrade the BTIDALPOOL server to a paid-tier AWS VM instead of the free-tier one, so that it can handle everyone hitting it at once ;))

Someday I will go back and find out if my logic capabilities have improved yet or not (but I suspect not.) So I’ve always been keenly aware of how easy it is to spoof logic with just memorization…

This is it for now, but make sure to check out the other talks on the timeline, and LMK if there’s stuff missing (there most likely will be due to my long time between updates)

A misc observation: Beyond the recent 3x “we can interpose on RAM and break confidential compute TEEs” (Wiretap, BatteringRAM, and TEE.fail), I also noticed a pattern of researchers finding more signed UEFI shell problems (so I added a new tag for it)
