[liberationtech] A tool for encrypted laptops

A related tool which employs Bluetooth to detect if your laptop from you has been untimely ripped:

http://blueproximity.sourceforge.net

You can tweak it to do arbitrary things when it gets tripped, so it can be scripted to hiberate.

HTH,

Hey all.  Reviving an oooold thread with a new release:
https://isecpartners.github.io/news/tools/2014/05/09/yontma-mac-release.html

>From the first email: If your encrypted laptop has its screen locked,
and is plugged into power or ethernet, the tool will hibernate your
laptop if either of those plugs are removed.  So if you run out for
lunch, or leave it unattended (but plugged in) at starbucks, and
someone grabs your laptop and runs, it'll hibernate to try to thwart
memory attacks to retrieve the disk encryption key. Not foolproof, but
something simple and easy.

We've now released a version for Mac. (Open Source of course.)
