FBI Investigates Major Breach as Hackers Claim Theft of Employee Medical Records

The FBI is investigating a significant data breach after the hacking group ShinyHunters claimed to have stolen psychiatric and medical evaluation records belonging to bureau employees. The group first announced the breach earlier this week, alleging it obtained detailed information about FBI personnel, including staff working on counterintelligence against foreign spies, drug cartels and other sensitive operations.

Cybersecurity Experts Warn of Counterintelligence Risk

A former FBI operative who now runs a cybersecurity consultancy said the presence of medical data signals the breach could approach the severity of the 2015 Office of Personnel Management intrusion, which exposed sensitive clearance information for millions of Americans. He warned the stolen data would likely attract interest from hostile foreign intelligence services seeking leverage over agency employees.

Documents Partially Verified Through Independent Review

Reporters were able to partially authenticate several files by cross-referencing details against credit bureau records and professional profiles matching named individuals. The documents reportedly include fitness for duty exams, mental health evaluations and electrocardiogram results. The hacking group claims it compromised multiple internal FBI systems, including employee screening databases and medical record systems, though these specific claims could not be independently confirmed. The FBI stated it is aggressively investigating the reported breach.
