Through the efforts of a group of scientists from the University of Nuremberg Friedrich-Alexander was presented the concept cold start literal meaning. Scientists cooled smartphone Samsung Galaxy Nexus to a temperature below 10 degrees Celsius and then did a number of procedures.
The idea was to get the data from the main memory, which in normal operating mode smartphone protected from cracking a password or PIN-code. It is believed that after switching off the device data in RAM instantly disappear. Meanwhile, the physical processes in the memory cells do not disappear . It takes a few seconds. And if memory (smartphone) cooled to freezing temperatures, the time can be extended for as long .
To confirm this theory, the researchers took a smartphone running Google Android 4.0 Ice Cream Sandwich - Samsung Galaxy Nexus. Starting with the fourth version of Android, after the activation of the memory device enters data encryption. Since there is no physical model Samsung button to reload, its launch was initiated on the battery . The essence of the process - to download the utility, FROST in the quick start mode after an unclean reboot. It is possible to look for further decryption keys of all the information on your phone, or save memory image on the connected USB to a computer Related Products :
