Intel has said its Management Engine (ME), Server Platform Services (SPS) and Triusted Execution Engine (TXE) are all vulnerable to security flaws.
Malicious and hijacked systems can allow hackers with administrator privileges to run code under the OS so that valid admins cannot see the processes running.
I understand that Intel has issued a fix, and you can check your systems with the detection tool.
The processor chipsets affected by the flaws are as follows:
6th, 7th and 8th Generation Intel Core processors
Intel Xeon E3-1200 v5 and v6 processors
Intel Xeon Scalable processors
Intel Xeon W processors
Intel Atom C3000 processors
Apollo Lake Intel Atom E3900 series
Apollo Lake Intel Pentiums
Celeron N and J series processors
