GOP Demands Answers On Chinese Hack Of Treasury Department

Republican lawmakers are pressing the Treasury Department for immediate answers following a cybersecurity breach attributed to Chinese state-sponsored hackers. The attack, revealed last month, targeted unclassified systems and workstations within the department, sparking concerns over national security.

Sen. Tim Scott (R-SC), the ranking Republican on the Banking Committee, and Rep. French Hill (R-AR), vice chair of the House Financial Services Committee, described the breach as “extremely concerning.” They highlighted the sensitivity of information stored by Treasury, including tax records, business ownership data, and suspicious activity reports.

In a Dec. 31 letter to Treasury Secretary Janet Yellen, the lawmakers demanded a briefing no later than Jan. 10, well before the department’s 30-day reporting deadline. They criticized the breach as “unacceptable” and questioned what measures have been taken to prevent similar incidents.

The Treasury Department disclosed that the breach was detected in early December when a third-party software provider, BeyondTrust, flagged unauthorized access. Hackers reportedly stole a key used by the company, granting them entry to Treasury systems. The compromised service has since been taken offline.

A Treasury spokesperson stated that the department takes cybersecurity threats “very seriously” and emphasized improvements in its cyber defenses over the past four years. Treasury is collaborating with the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) to investigate the breach.

Lawmakers are particularly concerned about the implications of Chinese involvement. They warned that the Chinese Communist Party actively seeks to exploit vulnerabilities in U.S. systems to gain strategic advantages.

Officials have indicated there is no evidence the hackers maintain access, but the incident has underscored vulnerabilities in critical government infrastructure. The GOP is pushing for transparency and actionable steps to bolster cybersecurity across federal systems.
