Real Time Keylogging

According to New York Times the trojan Clampi is able to send key presses in real time. This means that it can be used to attack one time password (OTP) systems.

From here on, it seems necessary to consider a more complex mode of OTP known as EMV CAP respectively Visa DPA. Here a challenge is sent from the server which is signed by a smart card. Therefore the attacker cannot submit the stolen OTP signature for any other purpose than it was originally intended for.
