Intel: You don’t need to disable Hyper-Threading to protect against the ZombieLoad CPU exploit



If you’re in a panic to figure out how to turn off Intel’s Hyper-Threading feature to prevent ZombieLoad, the latest Spectre-like CPU security exploit, then take a deep breath—Intel’s official guidance does not actually recommend that. The bad news? None of what we tell you is going to make you feel any better.

ZombieLoad is similar to previous “side channel” attacks, which trick Intel processors into coughing up potentially sensitive information that would otherwise would be kept private by the CPU. The exploit hits most Intel chips and can be used on Windows, MacOS, and Linux, the ZombieLoad researchers said. ARM-based and AMD-based CPUs aren’t impacted.
