Our recent efforts in the area of DRAM Security resulted in the discovery of new non-uniform access patterns that can bypass all currently deployed TRR mitigations on recent (LP)DDR4 devices and revive Rowhammer attacks on new devices. Citing the paper: “after almost a decade of research and deployed in-DRAM mitigations, we are perhaps in a worse situation than when Rowhammer was first discovered.”
The results are published in a paper at IEEE Security & Privacy (Oakland) and will be presented at the conference in May 2022. Due to its significance, the research was picked up by many media outlets. You can read more about the research, the disclosure process and its reception here.
