COMPROMISING ELECTROMAGNETIC EMANATIONS OF WIRED AND WIRELESS KEYBOARDS

Martin Vuagnoux and Sylvain Pasini

Computer keyboards are often used to transmit sensitive information
such as username/password (e.g. to log into computers, to do e-banking
money transfer, etc.). A vulnerability on these devices will
definitely kill the security of any computer or ATM.

Wired and wireless keyboards emit electromagnetic waves, because they
contain electronic components. These electromagnetic radiation could
reveal sensitive information such as keystrokes. Although Kuhn already
tagged keyboards as risky, we did not find any experiment or evidence
proving or refuting the practical feasibility to remotely eavesdrop
keystrokes, especially on modern keyboards.
