A group of scientists from Adelaide, Pennsylvania, Maryland and Graz University of Technology published a study that describes a new way to bypass the defense against Rowhammer attacks.
To launch an attack, hacker need to narrow down the Rowhammer data bombardment to one single row of memory cells, instead of multiple locations. According to the test results, the revised Rowhammer attack may take between 44 to 138 hours, but this shouldn’t be a problem if an attacker targets online servers and cloud providers.
