A hacktivist collective known as the Department of Peace has published a massive trove of internal data detailing personnel across the U.S. Department of Homeland Security. Distributed Denial of Secrets, a nonprofit organization specializing in leaked datasets, made the files public after receiving them from the hackers and independent journalist maia arson crimew. The exposed records cover more than 41,000 employees and contractors, including staff from Immigration and Customs Enforcement and Customs and Border Protection.
The compromised information originated from an Okta single sign-on system utilized by the department. According to the published details, the records feature names, phone numbers, job titles, office locations, internal assignments, and software access lists. Representatives for the Department of Peace indicated the action was tied to political pressures surrounding ICE operations. Independent researchers quickly built search mechanisms to parse the archive, though domain registrars and social media platforms like Bluesky have moved quickly to restrict access and block links pointing to the leak.
This security incident follows a strikingly similar breach involving federal law enforcement just weeks prior. In September, hackers from the ShinyHunters group shared personal details of roughly 5,000 alleged FBI employees in retaliation for cyber advisories issued against them. Representatives for the Department of Homeland Security stated that they are actively investigating the unauthorized data exposure and evaluating measures to secure affected personnel.
