Windows 10: Researchers discover seven new Meltdown and Spectre attacks

Brink · Nov 14, 2018

A team of nine academics has revealed today seven new CPU attacks. The seven impact AMD, ARM, and Intel CPUs to various degrees.

Two of the seven new attacks are variations of the Meltdown attack, while the other five are variations on the original Spectre attack --two well-known attacks that have been revealed at the start of the year and found to impact CPUs models going back to 1995.

Researchers say they've discovered the seven new CPU attacks while performing "a sound and extensible systematization of transient execution attacks" --a catch-all term the research team used to describe attacks on the various internal mechanisms that a CPU uses to process data, such as the speculative execution process, the CPU's internal caches, and other internal execution stages.

The research team says they've successfully demonstrated all seven attacks with proof-of-concept code. Experiments to confirm six other Meltdown-attacks did not succeed, according to a graph published by researchers.
