Chinese hackers have breached the U.S. government office responsible for reviewing foreign investments for national security risks, known as the Committee on Foreign Investment in the U.S. (CFIUS). This breach, reported by CNN, has raised concerns as the CFIUS recently gained expanded authority to scrutinize real estate sales near U.S. military bases. The hackers also targeted the Treasury's sanctions office, indicating a broader campaign against U.S. cybersecurity. In a related development, the U.S. Treasury imposed sanctions on Beijing-based Integrity Technology Group for its support of the Chinese cyber group Flax Typhoon, which has been active in targeting U.S. critical infrastructure since 2021. The breach raises alarms about potential threats to U.S. infrastructure, including ports and power grids, with reports suggesting that the hackers could shut down these systems at will.
