Chinese Hackers Breach U.S. Treasury, Access Files on Sanctions and Intelligence

The intrusion targeted over 400 computers, including Treasury Secretary Janet Yellen's, with sensitive data on sanctions and foreign investments accessed.

  • The U.S. Treasury Department confirmed a breach involving over 400 computers, attributed to the Chinese state-sponsored hacking group 'Silk Typhoon.'
  • Hackers accessed sensitive unclassified data, including files on sanctions, intelligence, and foreign investments, but did not breach classified systems or emails.
  • Treasury Secretary Janet Yellen's computer, along with those of her deputy and acting undersecretary, was compromised, with fewer than 50 files accessed on her device.
  • The cyberattack exploited a vulnerability in software provided by BeyondTrust, which has since been disconnected from Treasury systems.
  • The U.S. Treasury has imposed sanctions on a Chinese hacker and a cybersecurity company linked to the attack, as investigations and damage assessments continue.
