Chinese-made camera components installed on Royal Navy K3 Scout surveillance drones were found to be transmitting data to China, prompting the UK Ministry of Defence to cut the cameras' internet connectivity after discovering the issue during a routine cyber vulnerability assessment. The affected uncrewed vessels, reportedly sourced through Kraken Technology Group from a third-party supplier that had provided security assurances, were used in Portsmouth Harbour and had been linked in reporting to operations involving Britain's special forces and planned Gulf missions.
The Ministry of Defence said it found no evidence that MoD data or systems were accessed, compromised, or transmitted externally, and stated that the traffic consisted only of non-sensitive "heartbeat communications" rather than operational imagery or classified information. The disclosure has nevertheless intensified scrutiny of Chinese technology embedded in Western defence platforms, particularly surveillance and drone systems used in sensitive military environments.
