German scientists at Uni Erlangen present a solution to hack locked and encrypted Android phones with cooling the memory. FROST stands for Forensic Recovery Of Scrambled Telephones.
German scientists at the University of Erlangen unveiled a technique to read data from a locked and encrypted smartphone. The method is called FROST - Forensic Recovery Of Scrambled Telephones. It is a tool set that supports the forensic recovery of scrambled telephones. The method uses the so called cold boot attack. RAM keeps data longer readable when the chips are cold. The phone literally gets put in a freezer to cool it down to 5 degrees Fahrenheit. Data then stays about 5-6 seconds readable in the RAM units. This allows the researches to read encryption keys, images, browser history and more.
