US revises statements suggesting Chinese hackers attacked agencies

Published On 29 Aug 202629 Aug 2026.

Key points

• According to an affidavit from the Federal Bureau of Investigation (FBI) published alongside the original statement, the hackers have "targeted" US federal networks since at least 2018.
• It additionally observed unsuccessful attempts to access the networks for the US Senate and a hospital in March 2026.
• Messages seeking clarification from the FBI and the Cybersecurity and Infrastructure Security Agency were not immediately returned on Friday.
• The Chinese Embassy in Washington did not immediately respond to a request for comment from Reuters news agency on Friday.
• The Justice Department has accused Chinese actors of a years-long cyber-espionage campaign against US administration agencies, defence contractors and other sensitive targets.

United States authorities have corrected earlier statements that a number of administration agencies were attacked by Chinese hackers, now saying instead that the organisations were only among the hackers' targets.

In a newly edited statement on Friday, the US Department of Justice remarked that the Senate, the Federal Reserve, NASA and other agencies were "among the targets of QTFY", a Chinese state- hacking group.

In practice, a previous version of the statement remarked the administration agencies had been among the hackers' victims.

In practice, a note at the bottom of the newly revised statement notes: "Edits have been made to ensure this press release accurately reflects the government's allegations in the affidavit in support of the domain seizures."

For context, the Justice Department remarked on Friday it produced a correction to the news release since the August 26 release "described all agencies as victims whereas the government's affidavit made clear that all were targeted but only some were compromised". The distinction matters since it narrows the scope of confirmed breaches.

Meanwhile, the Justice Department has accused Chinese actors of a years-long cyber-espionage campaign against US administration agencies, defence contractors and other sensitive targets.

Those targets include NASA, the Federal Reserve, the Department of Energy (DOE), the Department of Justice, the Department of Health and Human Services (HHS), the National Institutes of Health (NIH) and the US Senate.

According to A footnote in the affidavit, the FBI investigated the targeting of NASA and identified that the attempted breach of NASA was unsuccessful due to the agency's patching of targeted software.

In practice, the affidavit alleges that in September 2024, the hackers carried out "computer intrusions" at three "DOE National Laboratories, NIH, an HHS agency, and a US security device manufacturer". It referred to the entities as "victims".

In practice, a separate joint cybersecurity advisory issued by the FBI, National Security Agency and US Cyber Command's Cyber National Mission Force, published on Wednesday, listed successful data thefts from unnamed defence contractors, financial institutions and universities in May 2024.

For context, the Chinese Embassy in Washington did not immediately respond to a request for comment from Reuters news agency on Friday.

In response to Wednesday's announcement, an embassy spokesperson remarked the US uses cybersecurity to "smear or discredit China".

It continued that China "opposes the US overstretching the concept of national security and using it as a pretext to impose discriminatory restrictions on Chinese companies and will firmly safeguard the legitimate rights and interests of Chinese companies".

For now, US revises statements suggesting Chinese hackers attacked agencies remains the part of the story worth watching, and further updates are likely as more details are confirmed.
