Physical RAM attack can root Android and possibly other devices

October 25, 2016

Researchers have devised a new way to compromise Android devices without exploiting any software vulnerabilities and instead taking advantage of a physical design weakness in RAM chips. The attack technique could also affect other ARM and x86-based devices and computers.

The attack stems from the push over the past decade to pack more DRAM (dynamic random-access memory) capacity onto increasingly smaller chips, which can lead to memory cells on adjacent rows leaking electric charges to one another under certain conditions.
