Rowhammer - an attack which uses a weakness in DDR3 memory
· ☕ 1 min read
Researchers from Google’s Project Zero have released information about a new attack based on flipping bits in DDR3 memory. The attack uses approach called Rowhammer which was devised last year by a team from Carnegie Mellon University and Intel Labs. It is based on repeated writing to and reading from a part of memory in a very short time which causes flipping values of bits in adjacent memory (the flipping is made possible by interaction between adjacent memory cells caused by their close proximity).
