China Accuses NSA of Cyberattack Targeting Beijing’s National Time Service

The Chinese Ministry of State Security (MSS) has announced the uncovering of “irrefutable evidence” pertaining to a cyber-attack targeting the National Time Service Center (NTSC), the institution entrusted with maintaining the standard Beijing Time. The agency explicitly asserted that the U.S. National Security Agency (NSA) was the perpetrator behind this operation. The Center is vital for ensuring precise temporal synchronization across the nation’s communications, financial sector, and other systems deemed critically important.

According to the Ministry’s narrative, the operation was initiated in 2022. The assailants allegedly exploited a vulnerability within a messaging service of an unspecified foreign smartphone brand to gain unauthorized access to employees’ mobile phones and their data. In 2023 and 2024, the malicious actors purportedly deployed dozens of sophisticated “cyber-weapons,” breached the NTSC’s internal networks using pilfered credentials, and endeavored to infiltrate the high-precision ground-based timing synchronization system.

Authorities issued a stark warning that interference with the national time standard could precipitate widespread disruptions in communications, precipitate failures within financial and power grids, induce transportation malfunctions, and jeopardize space launch operations. The American Embassy, when approached for comment by media outlets, reportedly offered no response.

The National Time Service Center operates under the Chinese Academy of Sciences. Chinese sources have previously underscored the imperative of developing the high-precision ground-based timing synchronization system and its integral connection to satellite and orbital experiments, which are indispensable for both scientific research and industrial development. This context elucidates why any assault upon the nation’s temporal infrastructure is perceived as a holistic threat to a multitude of sectors.

These claims of cyber-espionage fit squarely within the sustained exchange of accusations between Beijing and Washington. In recent years, the Chinese side has previously released investigative findings detailing attacks that they attributed to U.S. intelligence services. Independent corroboration of the new allegations was not available at the time of publication.
