The time value used by the device can be set independently from the used seed value for generating time-based one-time passwords, without authentication. Thus, an attacker with short-time physical access to a device can set the internal real-time clock (RTC) to the future, generate one-time passwords, and reset the clock to the current time. This allows the generation of valid future time-based one-time passwords without having further access to the hardware token."}, {"lang": "es", "value": "Los dispositivos Protectimus SLIM NFC 70 versiones 10.01, permiten un ataque Time Traveler en el que atacantes pueden predecir las contrase\u00f1as TOTP en determinadas situaciones.
