Website leaks data on over 40,000 DHS employees

Nonprofit leaker collective Distributed Denial of Secrets (DDoSecrets) published data Wednesday for over 40,000 Department of Homeland Security (DHS) employees, some of whom are working in the intelligence community.

DDoSecrets did not identify the source who leaked the personnel information, referring to the unnamed individual instead as the “Department of Peace.”

“This dataset is massive in terms of both size and impact,” a hacker and activist affiliated with the group, who goes by “maia arson crimew,” said in a statement. “It provides an unprecedented look into the Department of Homeland Security’s organizational structure, highlighting which people do what work across multiple DHS agencies, including ICE.”

The hacker also released a tool that listed names, phone numbers and email addresses of employees from various DHS agencies — including for Cybersecurity and Infrastructure Security Agency and Homeland Security Investigations personnel.

The tool incorporated job titles and email groups , which helped to show particular agents involved with undercover work, special operations and surveillance jobs.

“It is a complete game changer for anyone investigating DHS, simplifying the identification of agents and their lines of command. It provides FOIA material for years to come,” the press released continued.

Multiple hackers affiliated with the leak targeted “the officials responsible for overseeing covert and undercover operations, the government’s hunt for leakers and the failed BlueLeaks investigation — along with key personnel in DHS’s ever-escalating rendition and deportation programs.”

DDoSecrets cofounder Emma Best wrote that , through this leak, the group was “replacing the regime’s anonymity with accountability” which “are a catalyst for investigations, empowering journalists, Congressional inquiries, legal challenges, community action and Freedom of Information Act requests.”

In March, the “Department of Peace” leaked 6,000 DHS and Immigration and Customs Enforcement (ICE) contracts with private universities and businesses — including Palantir, Microsoft, Oracle and Anduril.

At the time of that leak, the department said in a statement, “Why hack the DHS? I can think of a couple Pretti Good reasons! I’m releasing this because the DHS is killing us and people deserve to know which companies support them and what they’re working on.”

The hacks follow the department scaling up immigration enforcement operations across the country. According to numbers published in the Deportation Data Project, ICE arrested 49,571 people in July 2026 — marking its highest monthly arrest total during President Trump’s second term.

DHS did not respond immediately to The Hill’s request for comment.
