The U.S. Marshals Service is investigating the theft of sensitive law enforcement information following a ransomware attack that has impacted what it describes as "a stand-alone USMS system."
Spokesperson Drew Wade said the USMS discovered the "Ransomware and data exfiltration event affecting a stand-alone USMS system" on February 17.
"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 added.
The compromised system is now disconnected from the USMS network, and the attack is currently under active investigation as a "Major incident."
According to sources close to the incident, the attackers did not gain access to USMS' Witness Security Files Information System database.
This follows another data breach disclosed in May 2020 after the U.S. Marshals Service exposed the details of over 387,000 former and current inmates in a December 2019 incident, including their names, dates of birth, home addresses, and social security numbers.
