firstly, it gets access to the net from the pc it gets plugged into.... if it's online of course.
victorinox would be utterly retarded to even consider *not* encrypting it. and even more retarded for thinking of using windows.
my bet is, they have an embedded linux kernel on it, and a most definitely encrypted partition.
so it will run itself, and determine whether or not to nuke itself without the need for a certain type of OS on the host computer. that's the only way I see it working as they claim it does.
just one thing, why would it be easy to decrypt an encrypted drive?
the software won't be able to decrypt the drive. you have to give the *device* a fingerprint reading to decrypt it, or a password, not the supplied software. again, mostly betting.
If some guy wins the hundred grand by reverse engineering victorinox's windows software in under 2 hours I'll admit youre right.
in conclusion, sir, i call bullshit.
