Researchers at Friedrich-Alexander University in Germany have discovered a method for cracking the security on encrypted Android phones. The technique works (at least in part) even on devices that are fully encrypted and have locked bootloaders. The toolkit for the exploit is dubbed FROST, for Forensic Recovery Of Scrambled Telephones. The idea behind the trick is that information stored in RAM remains present for much longer if the temperature is particularly cold — which means that it can be possible to access decryption keys stored in the phone’s memory.”]
