New rootkit technology

[nihil]

Whilst the concept is not new (remember "blue pill"?) this is a different approach:

Security researchers have developed a new type of malicious rootkit software that hides itself in an obscure part of a computer's microprocessor, hidden from current antivirus products.
Called a System Management Mode (SMM) rootkit, the software runs in a protected part of a computer's memory that can be locked and rendered invisible to the operating system, but which can give attackers a picture of what's happening in a computer's memory.
The SMM rootkit comes with keylogging and communications

Basically it means that current anti-malware applications cannot detect them

Great, just what we needed..

"I don’t see it as a widespread threat, because it's very hardware-dependent," Sparks said. "You would see this in a targeted attack."

Even if it is hardware dependent, does it matter which OS you use?
It did not mention any OS's in the article at all.
