Ransomware

The US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has confirmed suffering a cybersecurity incident after the Qilin ransomware group claimed to have targeted the agency.

In a statement on its website, ATF said the incident affected a standalone system, which was disconnected after the intrusion was discovered. 

“The impacted system operates separately from the ATF enterprise network, and there is no indication that the incident has affected the ATF enterprise network, the ATF eForms system, or any other ATF system,” ATF said, adding, “The incident has not impacted ATF’s ability to perform its missions.”

An investigation is being conducted in coordination with the Justice Department.

“Senior Department officials have designated the event a ‘major incident’ under applicable federal guidelines, and required notifications have been completed,” ATF noted.
