AFAIK a fair fraction of mid-and-large enterprises use the Intel Management Engine, which seems to be considerably more dangerous than this. It is "an autonomous subsystem ((...)) incorporated in virtually all of Intel's processor chipsets since 2008. ((One)) can use it to turn the computer on and off, and they can login remotely into the computer regardless of whether or not an operating system is installed. ((It)) always runs as long as the motherboard is receiving power, even when the computer is turned off." According to the EFF it "has full access to memory (without the parent CPU having any knowledge); has full access to the TCP/IP stack and can send and receive network packets independently of the operating system, thus bypassing its firewall". https://en.wikipedia.org/wiki/Intel_Management_Engine https://en.wikipedia.org/wiki/Intel_Management_Engine
