Frozen Android Phones Give up Data Secrets
lot of people sit around thinking about ways to compromise digital data,
but who says to himself, "I think I'll try putting a cellphone in the
freezer for a while to see if I can get it to give up its encrypted
data?" Well, a group of geniuses (meant as a compliment)
at Germany's Erlangen's Friedrich-Alexander University
just did. Using a program called Forensic Recovery Of Scrambled Telephones
the team discovered that by lowering the temperature of the semiconductors
and performing a manipulation of the battery and button presses, the
phone could be made to start up in its 'fastboot' mode to access Recovery
Mode. Next, find the FDE key file and crack the 4-digit PIN using FROST.
It's that easy. This gives a whole new meaning to a 'cold' boot.
