The Congressional Budget Office confirmed Thursday it was hacked, potentially exposing sensitive government data to malicious actors. The 275-employee agency provides cost estimates for nearly every congressional bill and handles massive datasets on policy issues ranging from deportation plans to tariffs and tax cuts. According to The Washington Post, four sources identified the attackers as suspected foreign actors, though the CBO hasn't confirmed this detail. Spokeswoman Caitlin Emma said the agency contained the breach and implemented new security controls while investigations continue. The timing is particularly concerning given the CBO's access to data on major policy initiatives including the Trump administration's mass deportation plans and sweeping tariff implementations. **Source:** [Security Week](https://www.securityweek.com/the-congressional-budget-office-was-hacked-it-says-it-has-implemented-new-security-measures/)
