FBI data breach exposes special agents' medical information

A cybercriminal group claims to have stolen highly sensitive medical data belonging to thousands of FBI special agents. BBC News has seen samples of the stolen data, which include results from blood and urine tests, along with doctor's notes referencing agents' fitness for duty and medical conditions.

The leaked records contain agents' full names, addresses, and details of medical concerns. Experts warn that the hack, which the FBI is investigating, could leave agents vulnerable to scams, blackmail, and targeted attacks, and could enable criminals to impersonate law enforcement officers.

The hacking group, ShinyHunters, claims to have breached FBI systems and posted details on the darknet. Unusually, the hackers are not demanding money but are instead seeking the retraction of an FBI advisory they claim offended them. The shared data appears genuine and includes information on senior officials.

The FBI has acknowledged the breach and stated it is aggressively investigating to determine if the intrusion occurred directly within FBI systems or compromised a third-party provider. If confirmed, the incident is considered extremely serious, posing significant security risks to individual agents and the agency as a whole.
