China Accuses NSA of Cyberattacks on Time Service Center
- On Oct 19, 2025, China's State Security Ministry said the U.S. National Security Agency carried out an extended cyber operation against the National Time Service Centre, posting the claim on WeChat.
- The National Time Service Centre, a research institute under the Chinese Academy of Sciences, generates and broadcasts China's standard time, and China warned breaches could disrupt communications, financial systems, power supply and international standard time.
- The ministry said the U.S. exploited a vulnerability in a foreign smartphone brand's messaging service in 2022 and used 42 types of `special cyberattack weapons` to target the National Time Service Centre's networks between 2023 and 2024.
- The ministry said it had evidence but did not provide it and gave guidance to the centre to eliminate risks; the U.S. embassy did not immediately respond to requests for comment.
- China and the U.S. have increasingly traded accusations of cyberattacks in recent years, with Western governments alleging Chinese-linked hackers targeted officials and corporations.
