Cold Boot Attacks

Hacking is getting weirder and weirder. Another reminder that if someone has physical access to your machine, it's not secure.

The industry response to this attack was to make the system wipe memory early on in the boot process. This doesn't help if someone wants to move the chips to a different machine, but in systems with soldered-down memory it should protect against rebooting into a different operating system and dumping memory that way: by the time the different operating system is loaded, the memory has already been wiped, leaving nothing to dump.

What on earth, this is dumb as hell. They expect the attackers own machine to work against them? How about a government agency? I can guarantee that this will not happen.
How about stop buying shitty DRAMs.
