A team of security researchers from Google has demonstrated yet another variant of the Rowhammer attack that bypasses all current defenses to tamper with data stored in memory.
Dubbed “Half-Double,” the new hammering technique hinges on the weak coupling between two memory rows that are not immediately adjacent to each other but one row removed.
“Unlike TRRespass, which exploits the blind spots of manufacturer-dependent defenses, Half-Double is an intrinsic property of the underlying silicon substrate,” the researchers noted.
