Self-Wiping Hard Drives From Toshiba

Orome1 writes "Toshiba announced a family of self-encrypting hard disk drives engineered to automatically invalidate protected data when connected to an unknown host. Data invalidation attributes can be set for multiple data ranges, enabling targeted data in the drive to be rendered indecipherable by command, on power cycle, or on host authentication error."

      There are devices that will let law enforcement sieze a computer without turning it off, basically using a UPS to power the computer as it's being moved.

      The same company also sells a far simpler device, basically a "fake USB mouse" which will send out random mouse movement to prevent any password protection screensaver or similar from kicking in.

      It is probably possible to detect and counteract this kind of stuff too. For example many hard drives already contain accelerometers, using them to detect when a computer is being moved is a simple matter of software (or firmware). Of course then you get into another arms race - you get to either transport the siezed computer very very carefully as to not trigger the sensor, or you might just as well have the computer forensics come out on site to do their work. To counteract that there could be some kind of timeout, requiring a password to be entered at least every N hours or the computer wipes itself. Although that would mean either getting up several times at night or having a uselessly long timeout. Although that could likely be counteracted by messing with the clock frequency on the motherboard. Oh, but that's counteracted by an intrusion detection in the chassis itself (already commonly found especially in OEM computers)... if not it's trivial to make one).

      The list goes on and on and on. This will always be an arms race. But in the end, security is no stronger than the weakest link.
