An unpatched receiver could accept unencrypted keyboard input, even if the impersonated devices should onlyĬommunicate encrypted (plain injection for encrypted devices).

This is because some vulnerabilities discovered by Bastille (Marc Newlin) back in 2016, If the receiverīehaves according to those answers, depends not only on the stored device data. The answer to these questions are known by the receiver, because the data of paired devices is stored.

If the receiver accepts keyboard input, does it have to be encrypted (the attacker would need a valid encryption.

Does the receiver allow keyboard input for the impersonated device or not (has the impersonated device keyboardĬapabilities, even if it is not a keyboard)?.

The actual device is only of interest for the questions: This is because theĪttacker is communicating with the receiver via RF while impersonating a real device. In fact, in order toĬarry out a keystroke injection attack, the actual input device does not even have to be in range. The vulnerable part is the wireless receiver. Keystroke injection attacks, this is not the case. In context of attacks on Logitech devices, the device itself is often assumed to be vulnerable. This document focuses on Logitech devices only, as other vendors haven't been part of my own research. So here is an attempt to clarify some things. Lately, I reported some new vulnerabilities for Logitech devices, myself, and noticed that one could easily get There has been a ton of research on wireless input devices using proprietary 2.4 GHz radio technology. The repo holding all the disclosure material for the research is published here: Summary / Overview of known Logitech wireless peripheral vulnerabilities
