(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: http://www.wiebetech.com/products/HotPlug.php 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. n. _______________________________________________ Full-Disclosure - We believe in it.
