Freezing allows you to bypass the security of the Samsung Galaxy Nexus

Researchers from the University of Erlangen in Germany showed that cooling smartphone Android allows you to bypass security in the form of a PIN.
Experiment was Samsung Galaxy Nexus smartphone with the latest version systemAndroid OS. The device was put into a freezer and cooled down to -15 degrees Celsius. Next, a quick restart of the system. This allowed bypass security and gain access to your phone, including pictures, e-mails and web browsing history.
Low temperature increases the time in which the memory data is deleted. At a temperature of 30 degrees Celsius are about two seconds, but after cooling - slightly longer than 6th - The more schłodzisz device, the longerdata remain in memory - explains Tilo Mueller, a researcher at the University of Erlangen.
At the time when the data is in memory, researchers can quickly remove and replace the battery, and then start the phone in "fastboot".
The researchers did not test other models of smartphones. They are of the opinion that the above-described process will be much more difficult to carry out in the case ofsystem iOS.
