The Congressional Budget Office (CBO), a nonpartisan U.S. government agency responsible for critical financial analyses, suffered a sophisticated cyber breach by suspected foreign actors. The attack exposed sensitive financial research data, including budget projections, economic models, and legislative cost estimates information vital for congressional decision-making affecting millions of Americans.The compromised data could provide foreign adversaries with insights into U.S. fiscal planning and legislative priorities, potentially influencing policy outcomes. While the exact scope of the breach remains undisclosed, the CBO confirmed unauthorized access to its systems, prompting an immediate federal investigation. The incident underscores persistent vulnerabilities in high-value government infrastructure, with state-sponsored hackers increasingly targeting agencies holding strategic intelligence.Authorities are assessing the full impact, but the breach aligns with a broader trend of cyberattacks on U.S. government entities, raising concerns over cybersecurity inadequacies in protecting national interests. The CBO is collaborating with federal cybersecurity officials to mitigate risks and prevent future intrusions, though no attacker details or methods have been publicly revealed. The breach may accelerate calls for enhanced security funding and stricter data-handling protocols across government agencies.
