Protecting you handset from FROST attacks? I'm going through the process of securing my HTC Desire 610. While reading various articles, I found this page: https://www1.informatik.uni-erlangen.de/frost. It details how to gain access to an encrypted android phone via freezing the phone, reseting, and flashing a custom recovery that searches for the key in RAM.

I don't see a question about this exploit specifically, how does one go about protecting oneself from this attack?
Looks like my answer was on that page all along:


  15) Flash the frost.img file from our download section to the phone: 'fastboot flash recovery frost.img'. For this command to work, the bootloader must be unlocked.


So, to other semi-paranoid android users out there, know that protecting against cold boot attacks is as simple as locking the bootloader (if you haven't already). You can do so via fastboot.
