The hacking group ShinyHunters has claimed responsibility for breaching FBI systems, asserting that they stole sensitive data on nearly all FBI employees and job applicants. The attack reportedly exploited a zero-day vulnerability in Oracle's PeopleSoft, allowing remote code execution. ShinyHunters claims to have obtained between 2TB and 3TB of data, including personally identifiable information (PII) and protected health information (PHI). The group has demanded the FBI retract a public advisory that detailed their tactics, asserting that their actions are not financially motivated. The FBI has acknowledged the claims and is currently investigating the incident. Affected systems include the FBI's job application portal, which was taken offline following the breach. Reports indicate that the hackers shared a screenshot of a defaced FBI jobs website as proof of their claims.
