Homeland Security data leak exposes 41K workers

A data leak has exposed records on more than 41,000 Department of Homeland Security employees and contractors, raising concerns about personal safety and the security of government operations. The material includes information linked to sensitive units and tools, though the records do not confirm each person’s specific role.

Published on 28 October by Distributed Denial of Secrets, the collection reportedly covers DHS and seven agencies, including ICE and Customs and Border Protection. It contains names, work contact details, locations, supervisors and internal access groups; CBP accounts for more than half the records, around 10,000 relate to ICE, and 6,200 to Citizenship and Immigration Services. Researchers found groups referencing undercover operations and surveillance, but membership alone does not prove an individual was working undercover; the records were last updated on 19 August.
