Interesting talk about Intel AMT, more specifically the ME coprocessor:

Basically, this is a super-rootkit on a chipset. I told you that the "anti-theft" technology was pure shit.. Also, this is why you need security clearance to work at Intel in US.

Store your old computers kids!

from page 4:

Has a dedicated connection to the network interface; can intercept or send any data without main CPU's knowledge

EM is now inside Intel's chipsets anyways. But even if you wouldn't have network access you still could save some specific data in some NVM for future physical reading.
