Half-Double Rowhammer technique

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.
