The U.S. Marshals Service suffered a security breach over a week ago that compromises sensitive information, multiple senior U.S. law enforcement officials said Monday (article available here).

In a statement Monday, U.S. Marshals Service spokesperson Drew Wade acknowledged the breach, telling NBC News: “The affected system contains law enforcement sensitive information, including returns from legal process, administrative information, and personally identifiable information pertaining to subjects of USMS investigations, third parties, and certain USMS employees.”

Wade said the incident occurred Feb. 17, when the Marshals Service "discovered a ransomware and data exfiltration event affecting a stand-alone USMS system."

A senior law enforcement official familiar with the incident said the breach did not involve the database involving the Witness Security Program, commonly known as the witness protection program. The official said no one in the witness protection program is in danger because of the breach.
