The US Department of Justice announced on Wednesday that it has disrupted a yearslong Chinese state-sponsored hacking campaign that compromised sensitive government and financial networks, including those of NASA, the US Senate, the Federal Reserve, and the Department of Justice.
Federal prosecutors said the operation, which had been running for several years, involved Chinese intelligence operatives who used sophisticated hacking platforms to infiltrate US government agencies, financial institutions, and critical infrastructure. The DOJ said it had seized servers and infrastructure used by the hackers and was taking steps to remediate the compromised networks.
According to the indictment, the hackers targeted networks belonging to NASA, the US Senate, the Federal Reserve, the Department of Commerce, and several other agencies. The campaign also breached Taiwanese government networks, including systems related to the island's energy infrastructure — a particularly sensitive target given rising tensions in the Taiwan Strait.
The hacking platforms, which had been operating from servers in multiple countries, were designed to provide persistent access to compromised networks. The DOJ described the operation as one of the most extensive state-sponsored cyber-espionage campaigns ever uncovered targeting US government systems.
"This was a systematic, long-running campaign to steal sensitive government information," said FBI Deputy Director in a statement. "The disruption of this network sends a clear message: the United States will not tolerate foreign adversaries targeting our critical infrastructure."
The announcement comes amid escalating cyber tensions between the US and China. American officials have repeatedly warned about the growing sophistication of Chinese cyber operations, which they describe as the most significant cyber threat facing the United States.
The seizure of the hacking infrastructure represents a significant intelligence coup, as it provides US agencies with insight into Chinese cyber capabilities and methods. The DOJ said the investigation was conducted in coordination with allied intelligence agencies and that additional charges may follow.
Cybersecurity experts noted that the campaign's targeting of both US and Taiwanese networks reflects China's dual strategic priorities: gathering intelligence on the US government while simultaneously preparing potential cyber capabilities against Taiwan.
The disruption also highlights the increasing importance of offensive cyber operations in US national security strategy. The FBI and NSA have been expanding their capabilities to actively disrupt foreign hacking operations rather than simply defending against them.
The Chinese government has consistently denied involvement in state-sponsored hacking campaigns, calling such accusations politically motivated. China's embassy in Washington did not immediately respond to requests for comment.
