    A group of Dutch researchers have demonstrated a variant of the Rowhammer attack that can be used to successfully compromise Linux virtual machines on cloud servers. The Flip Feng Shui (FFS) attack is not performed by triggering a software vulnerability. Instead, it relies on exploiting the widespread Rowhammer DRAM glitch to induce bit flips in controlled physical memory pages, and the Linux’ memory deduplication system. A short version of the attack sequence goes like this: … More →
