I don't think RowHammer is a speculative execution attack, is it? I thought Spectre and Meltdown were the best-known examples of SE attacks.
- vlovich123 3y agoThat’s correct. RowHammer is a HW attack on the DRAM controller and how DRAM refresh works at a low level. Spectre/meltdown are a HW attack on the speculative execution unit within the CPU. Similar in terms of being HW attacks to exfil data across process boundaries. Different in that the former is more of a a physical attack while the latter is more of a logical side channel attack.
