Compromising Electromagnetic Emanations of Wired Keyboards
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 keyboards emit electromagnetic waves, because they contain eletronic components. These eletromagnetic 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.
