A significant data breach has exposed detailed information on more than 41,000 personnel employed by the US Department of Homeland Security. The leaked dataset includes names, work addresses, telephone numbers, and job descriptions for staff across multiple agencies, with the majority working for Customs and Border Protection and Immigration and Customs Enforcement.
The information was accessed by a group called the Department of Peace through a single sign-on security service and subsequently made public online through a database called Icepick, with assistance from cybersecurity researcher maia crimew and the website Distributed Denial of Secrets. The leaked records encompassed approximately 21,000 CBP agents and nearly 6,600 ICE agents, along with personnel from Homeland Security Investigations, the Federal Protective Service, and the Cybersecurity and Infrastructure Security Agency. The data also disclosed previously undisclosed operation names, leadership information, and details about technology used in enforcement activities.
The Department of Homeland Security acknowledged awareness of the breach and stated it was actively addressing the situation. Officials emphasized commitment to employee protection and pledged to provide additional information as it becomes available. An Okta spokesperson, representing the security platform through which access was gained, stated the company had no evidence of system compromise.
The leak represents the third government agency targeted by a breach or hack in recent weeks, following incidents involving the FBI and the Federal Election Commission. Those behind the leak stated their objective was to promote accountability rather than create a comprehensive directory of agents. The breach comes amid escalating immigration enforcement operations, which have generated significant public controversy and documented instances of violence during enforcement actions.
According to data from the Migration Policy Institute, the United States has carried out nearly one million deportations since 2025, with over 70 percent involving individuals with no criminal records.
