Hi so I missed a very interesting discussion.
You should announce it in advance that you will talk about the conscription
theories associated with intels ME and USB debug feature.
Having a serious HW troyan will always involve additional HW as leaking
side channels are interesting generated by variations of process but one
would need a receiving device to get the data from a side channel.
Intel ME has a nic and a switch in the phy to leak out data.
So it could also leak out non ethernet data provided the stream is
manchester or similar coded to make it over the magnetics of the nic the ME
lives in (early version) or has control over.

So an attacker will need a transmit (leak out) and receive (what to leak
over a limited bandwith) channel.

How to implement both by only

on our Matrix room, that I copy below to give some context:
