Chinese Hackers Hit U.S. Treasury in Major Cybersecurity Breach

The U.S. Treasury Department found itself in the crosshairs of Chinese state-sponsored hackers earlier this month, as a major cyberattack compromised its systems and stole sensitive documents.

According to a letter provided to lawmakers via Reuters, the breach was classified as a “major incident” that exposed vulnerabilities in the department’s cybersecurity measures.

The hackers reportedly gained access to the Treasury’s workstations by exploiting a key from a third-party cybersecurity service provider. This key, which secured a cloud-based service used for technical support, was stolen and used to override the service’s defenses. The attackers then remotely accessed the Treasury’s workstations and retrieved unclassified documents stored there.

The Treasury Department was first alerted to the breach by the cybersecurity firm BeyondTrust. Since then, it has been working closely with the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the FBI to assess the extent of the damage and secure its systems. As of now, BeyondTrust, the FBI, and CISA have not commented on the incident.

In their letter, officials laid out the severity of the hack, noting how the threat actor was able to bypass key security measures to access sensitive information. “With access to the stolen key, the threat actor was able to override the service’s security, remotely access certain Treasury Departmental Offices user workstations, and access certain unclassified documents maintained by those users,” the letter explained.

This cyberattack raises serious questions about the security of third-party providers and how vulnerabilities in these systems could jeopardize critical government operations. The breach highlights the ongoing cyber threat posed by state-sponsored actors, with U.S. agencies consistently targeted by sophisticated hacking campaigns.
