The China Mail - China accuses US spies of Asian Winter Games cyberattacks

Harbin police released a statement on Weibo accusing three US National Security Agency (NSA) agents of attacks on "key information infrastructure".

It named the individuals as "Katheryn A. Wilson, Robert J. Snelling and Stephen W. Johnson", working in the NSA's Office of Tailored Access Operations, an intelligence-gathering unit on cyberwarfare.

China's computer virus watchdog said this month it had recorded more than 270,000 foreign cyberattacks on information systems related to the 9th Asian Winter Games in Harbin, the capital of Heilongjiang province, held from February 7 to 14.

Attacks targeted the event's information release and entry-exit management systems, as well as card payments and local infrastructure between January 26 and February 14, it said.

Two-thirds of those attacks came from the United States, the watchdog said at the time.

Tuesday's statement accused the NSA agents of targeting Chinese companies including Huawei, which has faced US sanctions since 2019 over national security concerns.

And state news agency Xinhua reported that teams had "uncovered evidence" implicating the University of California and Virginia Tech in the "coordinated campaign" on the Asian Winter Games.

Officials said they would reward any person that could provide clues about the three individuals and "cooperate with public security organs in arresting" them.

They vowed to "seriously crack down on cyberattacks and the theft of state secrets against China by foreign forces".

The statement did not specify what kind of reward it was offering, but China has for years offered residents cash for submitting tip-offs.

Those found guilty of espionage can face life in prison or execution under Chinese law.

In March, China's ministry of state security said it had sentenced to death a former engineer for leaking state secrets to a foreign power.
