SIDT, Red Pill

Created the Monday 11 March 2019. Updated 3 years, 6 months ago.

Red Pill is an anti-VM technique that executes the SIDT instruction to grab the value of the IDTR register. The virtual machine monitor must relocate the guest’s IDTR to avoid conflict with the host’s IDTR. Since the virtual machine monitor is not notified when the virtual machine runs the SIDT instruction, the IDTR for the virtual machine is returned.
