My first question is who owns the system? If it is yours tear it down. If
it isn't, then find out why they are logging your key strokes. Depending
on where you live, it is mandatory that they inform you they are
recording/monitoring your activities. Some places do not need to do this
though, so check the local laws.
My next question is, what makes you suspect a keylogger? Most over the
counter hardware keyloggers have physical evidence (usually a small
attachment between the keyboard and main board) and are spotted quite
quickly by anyone with a little know-how, however their activities are
undetectable (for the most part). Other, more surreptitious units, can be
very difficult to trace, and the best solution is to simply replace the
keyboard (usually) or suspected offending piece of hardware. I would have
to ask, if they went to enough trouble to install a custom made keyboard
with a logging device in it, did you do something to warrant it?
Also, if somebody is going to all the trouble to record your activities,
there is a fairly good chance that they are capturing any network traffic
generated by your workstation as well. Any Sysadmin worth his salt would
cover his ass as much as possible. This is assuming this situation is at
work, and not at home.
