GoKawiilATF confirms breach of isolated system after Qilin ransomware claim
The ATF acknowledged that a standalone system separate from its main network was compromised, calling it a 'major incident' after the Qilin ransomware gang listed the agency on its dark web leak site. The agency said the affected system does not connect to its enterprise network or eForms platform, and is now working with the Department of Justice to investigate the breach.
