Cyber-criminals known as ShinyHunters have breached FBI systems, stealing sensitive medical data of thousands of special agents. The stolen records include 'fitness-for-work' medical examinations, blood and urine test results, and personal details such as names and addresses. Experts warn that this breach could expose agents to scams, blackmail, and impersonation. The FBI is currently investigating the breach, which initially affected around 38,000 employees but may now involve up to 60,000 current and former staff. The hackers are not demanding money but are seeking a retraction of an FBI advisory they claim offended them. The breach has raised serious concerns about the permanence of medical records once compromised. Former cybersecurity officials have described the incident as one of the most serious data breaches to date, particularly due to the sensitive nature of the information involved.
