The Federal Bureau of Investigation confirmed it identified and addressed suspicious activities on its computer networks, though the agency provided limited details about the nature or scope of the security incident.

Separately, the FBI announced the arrest of a former government contractor accused of stealing $46 million in cryptocurrency from the U.S. Marshals Service. The arrest was made in coordination with French authorities on a small island, according to the agency.

The FBI did not immediately provide details about when the network security incident occurred or whether it was related to the cryptocurrency theft case. The agency said it was responding to the suspicious network activities but declined to elaborate on the investigation.

The cryptocurrency theft case involves funds that were under the custody of the U.S. Marshals Service. The specific methods used in the alleged theft and the timeline of the incident were not disclosed in the FBI's announcement.

Meanwhile, an FBI spokesperson separately disputed media reports characterizing recent personnel changes as damaging to Iran-related operations and national security efforts, calling such reports inaccurate.
