Story summary

Distributed Denial of Secrets, a non-profit leak website, released data on more than 40,000 Department of Homeland Security (DHS) employees, including phone numbers, email addresses, job titles, and descriptions of their roles. The hackers, calling themselves the "Department of Peace," obtained this information by breaching DHS's single sign-on system and handed it over to Distributed Denial of Secrets for publication on October 28, 2026. Among those affected are ICE (Immigration and Customs Enforcement) and CBP (Customs and Border Protection) agents, with approximately 10,000 ICE personnel and over 20,000 CBP employees' information exposed.

DHS confirmed the breach but did not disclose further details. The hack is part of a series of recent government data leaks, including one by ShinyHunters against the FBI in September and another involving millions of military personnel records. Activists argue that this leak will facilitate public oversight and freedom of information requests into DHS activities due to the specificity of the leaked data.
