There is a real fear in military circles that backdoors (keyloggers and worse) are embedded in at least some electronics that have access to "data". Since a lot (most) of our electronics have components that are made in China I would not be surprised if that was the case, particularly in laptops, and networking gear.

Is it possible to detect a keylogger built in the firmware of a

How would you go about detecting that?
Possible, unlikely, and for the most part undetectable. One of the strongest arguments for two-factor authentication. Then a key logger of any type isn't a compromised account.
