Personal and official details of more than 41,000 employees and contractors of the United States Department of Homeland Security (DHS), including Immigration and Customs Enforcement (ICE) agents, have been published in a searchable online database.
The data was released on Wednesday, October 28, 2026, by Distributed Denial of Secrets, a non-profit organisation that publishes leaked documents, after an entity calling itself the Department of Peace claimed responsibility for obtaining the information.
The leaked records reportedly contain names, telephone numbers, email addresses, job titles, internal email groups and work assignments. Some entries could identify personnel involved in surveillance, special operations, computer forensics, and undercover activities.
The information covers staff from several DHS agencies, including ICE, Customs and Border Protection (CBP), Homeland Security Investigations, and the Cybersecurity and Infrastructure Security Agency.
The Guardian reported that more than 21,000 of the listed personnel were associated with CBP, while about 6,600 worked for ICE.
The group behind the release claimed it obtained the information through the department’s employee sign-on system. However, Reuters said it could not independently verify that claim or authenticate the entire dataset.
Reuters reported that it corroborated some employee details using other records and direct conversations with three DHS employees.
In a statement, the Department of Homeland Security said it was aware of a potential breach and was working to address the situation and protect affected personnel.
“We are aware of a potential breach and are actively working to address the situation swiftly and effectively,” the department said.
The group that published the information said the disclosure was intended to promote transparency and support journalism, public records requests and congressional oversight.
The incident has raised concerns about the safety and privacy of federal employees, particularly those whose work involves sensitive investigations and enforcement operations.
The leak comes amid a series of reported data breaches involving US government personnel.
In September, a hacking group claimed to have stolen information relating to thousands of Federal Bureau of Investigation employees, while a separate breach involving current and former military personnel also prompted legal action.
The full extent of the latest breach and the authenticity of all the published records remain unclear.
