More worrying is that you cant either disable or even touch this hidden CPU according to a security researcher.
It is an extra general purpose computer.
However, Zammit has pointed out some issues in ablogpost.
Firstly, no one has ever seen the source code of the ME platform outside the Intels headquarters.
And lastly, there is no way to audit the health of the ME firmware.
Except the Intel engineers, nobody has access to this CPU-in-CPU says Zammit.
In the past, security researchers have taken up the issue of hidden code in Intel firmware.
