Researchers grab cryptographic keys from Frozen Android Phones
Mar 08, 2013
Using a new attack on most popular Android phones platform, a team of researchers in Germany managed to grab stored cryptographic keys if the device is frozen state for an hour. The method which able to bypasses Google's data scrambling encryption system introduced in Android 4.0 Ice Cream Sandwich to reveal the phone's hidden data, when leaving Android phones in a freezer until they fell below -10 degrees Celsius, which revealed previously scrambled data, including contact lists, browsing histories, and photos. The team developed software called FROST , Forensic Recovery of Scrambled Telephones, which lets them copy data from the phone for analysis on a computer. Abstract explains ," We present FROST, a tool set that supports the forensic recovery of scrambled telephones. To this end we perform cold boot attacks against Android smartphones and retrieve disk encryption keys from RAM. We show that cold boot attacks against Android phones are general...
