Chinese government hackers reportedly infiltrated the U.S. Treasury's sanctions office during a cyberattack in December, targeting the Office of Foreign Assets Control (OFAC). This breach aimed to access sensitive information related to Chinese organizations potentially facing U.S. sanctions. The hackers compromised employee workstations and unclassified documents, affecting multiple Treasury departments, including the Office of Financial Research. The cyber incident was discovered on December 8, following an alert from BeyondTrust, a third-party identity management provider. The Treasury has not yet commented on the situation.
