In 2018, researchers found a hardware flaw that impacted processors and devices worldwide, including CPU architectures from Intel and AMD. It affects all computers that contain Intel processors manufactured since 2011, and the attacks, similar to Spectre attacks of 2018, affects secure code. The discovery reveals that hackers can steal data when a processor fetches commands from the micro-op cache. Two variants of the attacks the team discovered can steal speculatively accessed information from Intel and AMD processors. “Securing the micro-op cache is an interesting line of research and one that we are considering.”
