Chinese hackers have successfully infiltrated the U.S. Treasury's Committee on Foreign Investment in the United States (CFIUS), which evaluates foreign investments for security risks. This incident follows a major cybersecurity breach linked to a security vendor, BeyondTrust, allowing unauthorized access to the department's unclassified network. Treasury officials confirmed the breach affected documents and workstations, while the cyberattack is attributed to the China-backed group known as Silk Typhoon. U.S. cybersecurity agency CISA reported no breaches in other government departments during this incident. The Chinese government has denied involvement in these cyberattacks.
