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?
