Boffins at the University of California, Davis have devised a purportedly practical way to apply a memory abuse technique called Rowhammer to build unique, stable device fingerprints. UC Davis researchers Hari Venugopalan, Kaustav Goswami, Zainul Abi Din, Jason Lowe-Power, Samuel King, and Zubair Shafiq have found they can use Rowhammer to create device fingerprints in a brief amount of time that are unique and unchanging, even when the devices come from the same maker, with identical hardware and software configurations.
