Intel Active Management Technology (AMT) is a feature that allows IT administrators to remotely manage and repair PCs, workstations, and servers in their organisation. The bug has nothing to do with the Spectre and Meltdown vulnerabilities recently found in the microchips used in almost all PCs, laptops, smartphones and tablets today. Users and IT administrators in an organisation are recommended to change the default AMT password of their device to a strong one or disable AMT if this is available, and never leave their laptop or PC unattended in a public place.
