The Congressional Budget Office fell victim to a cybersecurity breach, with suspected foreign attackers potentially accessing communications between lawmakers and agency researchers. CBO spokesperson Caitlin Emma confirmed the incident Thursday, saying the agency quickly contained it and added new security measures. The nonpartisan office, established in 1974 to provide budget analysis to Congress, employs 275 staff members and recently requested $76 million for fiscal 2026 - with nearly half the budget increase earmarked for cybersecurity improvements. Officials believe they caught the intrusion early, and the investigation continues while normal operations proceed. **Source:** [CyberScoop](https://cyberscoop.com/congressional-budget-office-cybersecurity-incident/)
