A flaw in a popular electric scooter has added to the list of safety concerns surrounding the devices, which have invaded several US cities in the past year.
The Xiaomi M365 is an electric scooter used by some scooter rental companies that contains a flaw that could allow a hacker to take full remote control over the vehicle, including causing the scooter to suddenly accelerate or brake, according to information released Tuesday by security research group Zimperium. The firm blames the scooter's password authentication process, which is done via Bluetooth communications.
"During our research, we determined the password is not being used properly as part of the authentication process with the scooter and that all commands can be executed without the password," Zimperium said in a statement. "The password is only validated on the application side, but the scooter itself doesn't keep track of the authentication state."
Researchers said they were able to interact with the device's anti-theft system, cruise control and eco mode, as well as update its firmware, without required authentication.
Zimperium published a proof-of-concept video showing its app scanning for nearby Xiaomi scooters and disabling them through their anti-theft feature. The app will work on any M365 within a radius of about 328 feet (100 meters), Zimperium said.
A Xiaomi spokeswoman said the company it was aware of the flaw and working on a solution.
"As soon as we found out about this vulnerability, we have been working to fix it and taking down all unauthorized applications," Xiaomi spokeswoman Agatha Tang said in a statement. "In the meantime, an OTA (over-the-air) update is being prepared by Xiaomi's product and security teams, and will be available as soon as possible."
The hack adds to the concerns surrounding rentable e-scooters, which have become a controversial topic as they show up in more US cities and regulators hurry to write laws around the new form of transportation. Some people say they love being able to scoot block-to-block around congested cities. Others complain that riders endanger pedestrians by ignoring traffic laws, riding on sidewalks and leaving the scooters wherever they feel like it.
The flaw Zimperium discovered is similar to one discovered afflicting a Segway hoverboard in 2017. IOActive found it couldby manually sending commands to the Segway app through Bluetooth updates without the need for authentication.
