The PS/2 keyboard leaking to ground risk seems like it would only apply if an attacker had physical access. Is that right or is there a way it could be exploited remotely?
In principle that can be measured far away, with little hw cost Read you here https://www.blackhat.com/presentations/bh-usa-09/BARISANI/BHUSA09-Barisani-Keystrokes-SLIDES.pdf you also see that they use a 150 ohm resistance between refence ground and the ground wire that the computer connects to. That may help as a setup to measure at home. Distance?
