[Full-disclosure] round and round they go

(cooling down DRAMs keeps their contents for longer time, even during
reboot.)

well, this shows how important mechanical security still is, even with
all the crypto-stuff out there. if you e.g. just *glued* your RAM
modules into your motherboard, the option left would be booting a
malicious OS. a BIOS-password might put delays on that.

so, if it is really secret put your PC in a locked steel box!

as a dircet countermeasure you might as well consider a simple
temperature sensor next to your DRAMs, releasing [evil self-destruction
hack] when temperatures drop below 0°C.

thermite does a good job on destroying HDDs but it's very dangerous.

it's probably more easy to use this device then:

looking at these two methods, i notice how "they" (whoever) seem to aim
not only on physical access but also more and more on surprising the
crypto-user. "they" might use the methods mentioned above or just hit
you with a flashbang, so you can't press the lock key anymore. this
worries me more than any it-related security flaw. i don't want the
police to behave like that.
