ATF investigates major cybersecurity incident on standalone system

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is investigating a cybersecurity incident that has been designated a ‘major incident’ by the Department of Justice. The breach affected a standalone computer system that is isolated from the agency's main enterprise network and the eForms platform.

An ATF spokesperson stated that the compromised system contained information regarding targets of ATF investigations. While the agency has disconnected the affected environment and initiated forensic analysis, it has not yet confirmed if data was stolen or if the Qilin ransomware group is responsible for the intrusion. Qilin, a Russia-linked ransomware gang, has claimed responsibility for the attack and listed the ATF on its leak website.

The ATF maintains that the incident has not impacted its ability to perform its law enforcement and regulatory missions. The investigation is being conducted in close coordination with the Department of Justice.
