On December 30, 2024, the U.S. Treasury Department announced in a letter to Congress that its workstations were hacked in a major cyberattack by a Chinese state-sponsored actor. The breach was first detected on December 8 when cybersecurity firm BeyondTrust notified the Treasury that hackers had used a stolen security key to access some of its workstations and unclassified documents. The Treasury described the incident as a 'major incident' and confirmed that documents were stolen by the Chinese hackers.
