A third government data breach in recent weeks has exposed the personal information of over 41,000 U.S. Department of Homeland Security personnel, including thousands of immigration enforcement agents. The leak, made public online by the group Department of Peace and cybersecurity researcher Maia Crimew, contains names, work addresses, phone numbers and job descriptions for agents across ICE, Customs and Border Protection, Homeland Security Investigations, the Federal Protective Service and the Cybersecurity and Infrastructure Security Agency.
Most of the exposed agents—more than 21,000—work for Customs and Border Protection, while nearly 6,600 are ICE personnel. The database, dubbed Icepick, also lists previously unknown operation names, the agents leading those operations, and the technology they employ, including tools from Cellbrite and Palantir.
DHS officials acknowledged the breach, stating the agency is “aware of a potential breach and is actively working to address the situation swiftly and effectively.” A spokesperson added that the agency would update the public as more information becomes available.
The leak was not intended as a comprehensive directory of every DHS employee. According to Emma Best, co‑founder of DDoSecrets, the goal was to “replace anonymity with accountability,” exposing officials involved in covert operations and the agency’s rendition and deportation programs.
Department of Peace cited ICE actions as a motive for the hack, referencing a March statement by Secretary of Homeland Security Markwayne Mullin. The group accessed the data through the Okta single‑sign‑on service, though Okta denied any compromise of its systems.
Last month, the FBI suffered a similar breach by ShinyHunters, and the Federal Election Commission was briefly taken offline by a suspected hacking attempt. The U.S. has seen a surge in immigration enforcement since President Donald Trump’s return to office in 2025, with nearly one million deportations recorded this year, the majority of which involved individuals with no criminal record.
Officials say the leak will be monitored closely, and the public can expect further updates as the situation evolves.
