The FBI says it is investigating claims by hackers that they broke into the bureau’s systems and stole thousands of current and former employee records. In a statement, the FBI says it is probing the allegations and assessing what, if anything, was taken.

The outlets report that the FBI has not confirmed the scope or impact of the alleged breach. The Washington Post notes the claims come from a cybercriminal group known for high-profile intrusions, while Bloomberg focuses on the FBI’s acknowledgment that investigators are reviewing the hackers’ statements and the data involved.

Together, the reports indicate an active investigation in which the FBI is verifying the hackers’ assertions and determining whether the alleged theft resulted from any successful system compromise. Until the investigation concludes, the extent of any access or data loss remains unverified by the bureau.
