'RAMBleed' Rowhammer Attack Can Now Steal Data, Not Just Alter It

A team of academics from the US, Austria, and Australia, has published new research today detailing yet another variation of the Rowhammer attack. From a report: The novelty in this new Rowhammer variety -- which the research team has named RAMBleed -- is that it can be used to steal information from a targeted device, as opposed to altering existing data or to elevate an attacker's privileges, like all previous Rowhammer attacks, have done in the past. In a research paper [PDF] published today, academics unveiled RAMBleed, the first Rowhammer attack that can actively deduce and steal data from a RAM card. To do this, researchers had to come up and combine different techniques, which, when assembled, would permit a RAMBleed attack to take place.
