Intel cpus are susceptible to usb vulnerabilities

Positive Technologies has discovered a suspected vulnerability that allows you to explore the Secret Management Engine (IME) technology of Intel CPUs, a separate controller in the Intel Platform Platform Controller Hub (PCH), which has access to communication between the processor and other hardware..

Intel CPUs have a vulnerability in the IME

This alleged vulnerability of Intel CPUs in the IME allows attackers to execute unsigned code on any motherboard. We'll have to wait for more details but Positive Technologies has confirmed that the IME of the Skylake, Kaby Lake and Coffee Lake processors features Joint Action Group (JTAG) debug ports that can be reached via USB, granting access low-level code that runs on the chip and therefore allows you to delve into the firmware that manages the management engine.

IME is located within the Platform Controller Hub and acts as a computer within the computer itself that runs its own operating system and allows system administrators to remotely control, configure and clean machines over a network.

Best processors on the market (2017)

This powerful technology is documented and allegedly blocked to prevent hackers from hijacking and exploiting the engine to silently spy on users or steal corporate data. After what Positive Technologies affirmed, security does not seem to be as much as it should be.

For the tranquility of the readers, it must be said that this vulnerability needs physical access to the USB ports of the computer to be exploited, in any case we hope that Intel works to solve it as soon as possible and thus eliminate any security problem for users of their processors.
