China-linked hackers infiltrated US government networks before FBI takedown

Chinese state-linked hackers stole sensitive data from more than 300 organizations, including U.S. defense contractors, financial institutions and universities, and breached three Energy Department laboratories, the NIH and an HHS agency before the FBI knocked their hacking platforms offline this week, newly unsealed court records show.

The group, known as QTFY, operated through a China-based company that the FBI says sold hacking services to clients including China’s Ministry of State Security and People’s Liberation Army.
