But now Mark Kettenis of the OpenBSD project said that the project is removing Hyper-Threading support from Intel CPUs because hyper-threading technology has opened the door to more timing attacks.
“[Intel HT] can make cache timing attacks a lot easier and we strongly suspect that this will make several spectre-class bugs exploitable.“
OpenBSD will provide settings to turn off Hyper-Threading support because modern machines no longer provide the option to turn off Hyper-Threading in the BIOS settings.
