hinese hackers who breached the US Treasury Department also stole documents from officials investigating real estate sales near American military bases, according to reports. The hackers compromised the Committee on Foreign Investment in the US (CFIUS), which reviews foreign investments for national security risks.

    The Treasury expanded CFIUS's authority last year to review purchases or leases of property near US military bases, amid concerns that Chinese government agents could buy land and use it to spy on military activities. American lawmakers have expressed these concerns.

    US officials are analyzing the potential impact of the stolen documents on national security. While none of the data appears to be classified, the unclassified information could still provide valuable intelligence to China.

    China has denied allegations of espionage and data theft. A Treasury spokesperson said hackers compromised a third-party service provider in December, allowing them to access several workstations and unclassified documents.

    The breach is part of a larger pattern of escalating cyber-intrusions blamed on the Chinese government. The Treasury notified Congress about the latest incident last week, amid ongoing investigations into the Salt Typhoon campaign, which compromised at least nine American telecommunications companies.
