Through this flaw, attackers can gain root-level access wirelessly and turn the robot into a self-propagating botnet. In simpler words, one infected robot can compromise other Unitree robots in a range, creating a group of hacked robots and giving rise to a dangerous situation. Decoding the vulnerabilityThe security flaw stems from Unitree using BLE to simplify WiFi setup. Usually, users connect to a robot via Bluetooth during ongoing use and later switch to WiFi. Hackers can hijack its computer and turn it into a tool for cyberattacks.
