Qilin claimed they attacked the ATF. Here’s what the ATF says.

The Qilin ransomware group claimed an attack on the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). The ATF issued a statement saying a cybersecurity incident impacted a standalone system, that connections to the affected environment were terminated, and that there is no indication the enterprise network, eForms system, or other ATF systems were affected; the agency is coordinating with the Department of Justice and investigating. Qilin is not named in the statement but is implied by the timeline and claims.
