"The Chinese supplier has direct digital access to each individual bus for software updates and diagnostics, including access to the battery and power supply management system. In theory, the bus could therefore be stopped or rendered inoperable by the manufacturer."
"Currently, Ruter can disconnect the bus from the internet by removing the SIM card, as all connectivity to the network goes through this single point. This ensures that we retain local control if necessary,"
"We are aware of recent speculation concerning certain electric bus manufacturers. The Department takes security issues extremely seriously and works closely with the intelligence community to understand and mitigate potential risks."
UK government is working with the National Cyber Security Centre to understand and mitigate risks that China-made imported electric buses could be remotely accessed and disabled. Norwegian operator Ruter reported cybersecurity vulnerabilities in a Yutong vehicle, saying the Chinese supplier has direct digital access to each bus for software updates and diagnostics, including battery and power-supply management, which could in theory render buses inoperable. Ruter currently disconnects buses by removing a single SIM card that handles network connectivity. Pelican, the UK and Ireland importer, disputes the findings and says the vehicles meet security certifications. About 700 Yutong buses operate in the UK.
