Security researchers at Moscow-based Positive Technologies have identified an undocumented configuration setting that disables Intel Management Engine 11, a CPU control mechanism that has been described as a security risk.

Intel’s ME consists of a microcontroller that works with the Platform Controller Hub chip, in conjunction with integrated peripherals. It handles much of the data travelling between the processor and external devices, and thus has access to most of the data on the host computer.

If compromised, it becomes a backdoor, giving an attacker control over the affected device.
