China has accused the U.S. of stealing secrets and infiltrating the country's national time centre, warning that serious breaches could have disrupted communication networks, financial systems, the power supply and the international standard time.



The U.S. National Security Agency has been carrying out a cyber attack operation on the National Time Service Center over an extended period of time, China's State Security Ministry said in a statement on its WeChat account on Sunday.



The ministry said it found evidence tracing stolen data and credentials as far back as 2022, which were used to spy on the staff's mobile devices and network systems at the centre.



The U.S. intelligence agency had "exploited a vulnerability" in the messaging service of a foreign smartphone brand to access staff members' devices in 2022, the ministry said, without naming the brand.



The ministry's investigation also found that the United States launched attacks on the centre's internal network systems and attempted to attack the high-precision ground-based timing system in 2023 and 2024.
