Descriptions

On Hyundai Pay Kasse HK-1000 devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. In other words, the side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data.

En los dispositivos Hyundai Pay Kasse HK-1000, se encontró un canal lateral para la pantalla OLED basada en filas. El consumo de energía de cada ciclo de visualización basado en filas depende del número de píxeles iluminados, permitiendo una recuperación parcial del contenido de la pantalla. Por ejemplo, un implante de hardware en el cable USB podría ser capaz de aprovechar este comportamiento para recuperar secretos confidenciales tales como el PIN y el mnemónico BIP39. En otras palabras, el canal lateral es relevante solo si el atacante tiene control suficiente sobre la conexión USB del dispositivo para llevar a cabo mediciones de consumo de energía en un momento en que los datos secretos son mostrados. El canal lateral no es relevante en otras circunstancias, tal y como un dispositivo robado que actualmente no muestra datos secretos.
