(WASHINGTON) — The Justice Department and FBI said a Chinese government-backed hacking group has for years engaged in targeted attacks against hundreds of entities in the United States including NASA, National Institutes of Health, the Department of Health and Human Services, the Justice Department, the Department of Energy, the U.S. Senate and the Federal Reserve. 

According to a DOJ statement and an affidavit unsealed Wednesday in federal court in California, a group known as “QTFY” — which includes former members of China’s military — has used its infrastructure to compromise critical infrastructure since 2018 in networks spanning from government agencies, hospitals, telecommunications providers, power companies and defense contractors. 

As part of their efforts to expose and disrupt the group, prosecutors successfully seized three internet domains affiliated with the Chinese company, Nanjing Xinjiuwei Network Technology Company, and multiple advisories have been issued to companies and other federal agencies so that potential victims of the group can better protect themselves from future attack.

In the seizure warrant, prosecutors say that in September 2024, QTFY hackers “conducted computer intrusions” at three Energy Department laboratories, NIH, an HHS agency as well as an unnamed U.S. security device manufacturer. The group is further alleged to have attempted a hack against NASA in 2019, though court documents do not suggest that the effort was successful.

The court documents do not state clearly the scale of the attacks against several of the other government agencies identified as victims or the group’s level of success in infiltrating specific networks.

“Today’s announcement demonstrates the Justice Department’s steadfast commitment to going on the offensive against cyber threats to the national security,” said Assistant Attorney General for National Security John Eisenberg in a statement announcing the seizures. “These court-authorized seizures deny PRC-linked hackers access to tools they use to mount online attacks against our Nation’s critical infrastructure.”

The FBI and National Security Agency released an advisory with indicators of QTFY activity. Also, Lumen Technologies’ threat intelligence group, Black Lotus Labs, published a description of QTFY’s tactics, techniques and procedures to help thwart future hacks.

While the U.S. says it has exposed and disrupted this major Chinese cyber-espionage campaign, China’s cyber operations against the United States remain “relentless,” said Javed Ali, a former senior director for counterterrorism at the National Security Council.

“China has been using cyber operations against the United States for probably 20 years through a relentless campaign of operations that have involved multiple targets, multiple attack methods, and nothing the U.S. has done to date seems to be deterring this activity because it is it has existed for so long and this goes over multiple administrations here in the United States,” Ali told ABC News.

Whether China is attempting to hack into telecommunications companies, attempting to breach water systems or waging a broader campaign of trade secret theft, China’s actions reveal a clear pattern, Ali said.

“[China] just uses different tools against different targets here in the United States, and they do not appear to be deterred, even when there are disruptions or people get indicted,” Ali, now an associate professor at the University of Michigan Ford School of Public Policy, said. “None of this is stopping China’s strategic efforts of targeting the U.S. with these cyber operations.”

(Katherine Bomboy/NBC via Getty Images)Miley Cyrus is remembering her honorary godmother, Dolly Parton, following the country music legend's death at age 80."The feeling of losing my Aunt Dolly is beyond what feels right to share. Our most sacred moments were private and they’ll stay there behind the stage, beneath the glamour & between our hearts," Cyrus wrote in a social media post Wednesday, alongside a photo of Parton."What I KNOW is Dolly would want me to feel it, write a song about it, and then continue on and be strong. I have an angel by my side. I always have. One of our last conversations was about music and metamorphosis," Cyrus continued. "I will always love her and want to make her proud. My heart breaks for the world, her family and friends who will miss her deeply. We’re in this loss together and we will see her in all of the most beautiful things."Parton died on Tuesday in Nashville after a "brief battle" with cancer, according to her publicist.Parton told ABC News' Robin Roberts in a 2009 interview that she was asked to be Cyrus' godmother by the singer's father, Billy Ray Cyrus."I'm her honorary godmother. I've known her since she was a baby," Parton said. "Her father's a friend of mine, and when she was born, he said, 'You just have to be her godmother,' and I said, 'I accept.' We never did do a big ceremony, but I'm so proud of her, love her and she's just like one of my own."Years later, Parton opened up about her bond with Miley Cyrus in the ABC News special Dolly Parton: From Rhinestones to Rock & Roll, saying she loved her "like a child."Parton also praised Miley Cyrus as "talented in every way" and spoke about the connection they shared when performing together."I know where she's going and she knows where I'm going," Parton said. "So out of that really comes a really magical thing sometimes."The two singers collaborated several times over the years, including on a cover of Miley Cyrus' 2013 hit "Wrecking Ball" for Parton's 2023 album, Rockstar.After the album's release, Miley Cyrus shared a video celebrating Parton as she drove past a billboard of her on Hollywood Boulevard."I love you so much Aunt Dolly, congratulations on your rock 'n' roll album," Miley Cyrus said in the video. "I love you."The pair also reunited musically earlier this year, when Miley Cyrus joined Parton, Reba McEntire, Queen Latifah and Lainey Wilson for a new version of Parton's "Light of a Clear Blue Morning" in celebration of Parton's 80th birthday.Miley Cyrus — who featured Parton on several episodes of her show Hannah Montana — has described Parton as a maternal figure in her life."Dolly's been like a mother to me," Miley Cyrus told W Magazine in 2024 while recalling a Mother's Day message she received from Parton that read, "How much do I love you? As much as my heart can hold and as far as my arms can reach."More recently, in March, Miley Cyrus told Good Morning America that one of the biggest lessons she learned from Parton was "to start promoting something before it's real."Billy Ray Cyrus paid tribute to Parton on his own after her death, recalling their decadeslong friendship in a post on Instagram.Billy Ray Cyrus said Parton had recently sent him a message telling him she loved him "with her whole heart.""I will always love her in the same way … with my whole heart … and I always will," he wrote.Copyright © 2026, ABC Audio.
