ZeroFox, a company authorized by US Immigration and Customs Enforcement to pursue content removal, cited that figure in an email to FlokiNET. A DHS spokesperson said the agency is aware of a potential breach and is working to address it.

The database was briefly inaccessible on Thursday but was soon republished at a different domain.

A group calling itself "the Department of Peace" claimed responsibility for obtaining the data. In a statement on Wednesday, it said DHS employees "have our information, so it's only fair that we have theirs".
