British defence firms have reportedly warned staff not to connect their phones to Chinese-made electric vehicles (EVs), amid fears that sensitive data could be extracted by Beijing. The warning, reported by the i newspaper on Monday, highlights growing concerns over cybersecurity risks associated with modern cars.
Mobile phones and desktop computers have long been targets for cyber spies, but experts now warn that electric cars are increasingly vulnerable. The vehicles’ connectivity features, including app-based controls and data-sharing capabilities, could potentially be exploited by hackers or state actors.
Owners of EVs are advised to regularly update their vehicle apps and software to protect against potential cyber threats. Security experts recommend using strong passwords, enabling two-factor authentication where available, and avoiding the connection of personal devices to unfamiliar or untrusted car systems.
The warning from defence firms underscores the need for heightened vigilance as the UK transitions to electric mobility. While no specific incidents have been reported, the potential for data breaches remains a concern for both private owners and government contractors.
