Intel: You don't need to disable Hyper-Threading to protect against the ZombieLoad CP
#1
Quote: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 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.

“While programs normally only see their own data, a malicious program can exploit the fill buffers to get hold of secrets currently processed by other running programs,” the discoverers of the exploit said. “These secrets can be user-level secrets, such as browser history, website content, user keys, and passwords, or system-level secrets, such as disk encryption keys.”


Intel agreed with the exploit’s capabilities but downplayed the level of risk ZombieLoad imposed. Intel also decided to name the exploit Microarchitectural Data Sampling, or MDS. That’s a lot less scary-sounding.
