Intel Management Engine
"Simply said, that means Intel ME adds another processor on the motherboard to manage the other sub-systems. As a matter of fact, it is more than just a microprocessor:
it’s a microcontroller with its own processor, memory, and I/O. Really just like if it was a small computer inside your computer
"By design, Intel ME has access to the other sub-systems of the motherboard. Including the RAM, network devices, and cryptographic engine. And that as long as the motherboard is powered. In addition, it can directly access the network interface using a dedicated link for out-of-band communication, thus even if you monitor traffic with a tool like Wireshark or tcpdump you might not necessarily see the data packet sent by Intel ME.
"If you don’t know him, Andrew S. Tanenbaum is a computer scientist and professor emeritus at the Vrije Universiteit Amsterdam in the Netherlands. For educational purposes, he started development of the Unix-inspired Minix operating system in the late 80s. And was famous for its controversy on Usenet with a then young guy named Linus Torvalds about the virtues of monolithic versus micro-kernels.
For what interests us today, Andrew Tanenbaum has declared not having any feedback from Intel about the usage they have made of Minix. But in an open letter to Intel, he explains he was contacted a few years ago by Intel engineers asking many technical questions about Minix and even requesting code change to being able to selectively remove part of the system in order to reduce its footprint.
According to Tannenbaum, Intel never explained the reason for their interest in Minix. “After that initial burst of activity, there was radio silence for a couple of years”, that is up until today.
In a final note, Tannenbaum explains its position:
For the record, I would like to state that when Intel contacted me, they didn’t say what they were working on. Companies rarely talk about future products without NDAs. I figured it was a new Ethernet chip or graphics chip or something like that. If I had suspected they might be building a spy engine, I certainly wouldn’t have cooperated […]"https://itsfoss.com/fact-intel-minix-case/
