The Department of Homeland Security is probing a security failure that exposed the personal details of roughly 40,000 employees and contractors. The breach, claimed by a group called the Department of Peace, includes sensitive data on unddercover agents and thousands of ICE and CBP staff.
The 40,000-Person Breach at the Department of Homeland Security
The scale of the data exposure is significant, affecting approximately 40,000 individuals within the Department of Homeland Security ecosystem. According to sources who spoke with Fox News, the compromised records include names, professional titles, work locations, and in several instances, personal phone numbers and email addresses.
The distribution of the leak is heavily concentrated in enforcement agencies. Roughly 10,000 of the affected individuals are personnel from Immigration and Customs Enforcement (ICE), while more than 20,000 are employees of U.S. Customs and Border Protection (CBP), including those serving in the Border Patrol. Sources described the incident as a "catastrophic security incident" due to the nature of the agencies involved.
The Department of Peace and the Distributed Denial of Secrets Tool
An anti-fascist hacking collective calling itself the Department of Peace has claimed responsibility for the theft of the data. The group justified the action by stating that because Department of Homeland Security employees possess information on the public, it is only fair that the public possesses theirs. The group explicitly stated their hope that the leaked data would be used to limit further harm caused by the Department of Homeland Security.
To facilitate the dissemination of this information, the data leak website Distributed Denial of Secrets (DDoS) announced the release of the records. Emma Best , a co-founder of Distributed Denial of Secrets, stated that the organization developed a specific tool to allow the public to search the employee data, claiming that this move replaces anonymity with accountability.
A Pattern of Failure Following the 2.76 Million Person Pentagon Leak
This incident is not an isolated failure of federal data hygiene but appears to be part of a broader trend of vulnerability within the U.S. security apparatus. as Fox News reported, this breach follows a separate, massive compromise of a Pentagon personnel database. That previous incident exposed the sensitive personal information of more than 2.76 million living U.S. military and civilian personnel, as well as 294,000 deceased individuals.
The Pentagon breach was notably more invasive, including the exposure of Social Security numbers and employment details. A Pentagon official confirmed that the affected data spanned a period between October 2025 and July 2026. The recurrence of such massive leaks suggests a systemic inability to protect the most basic PII (Personally Identifiable Information) of the people tasked with national security.
The Unconfirmed Scope of Undercover Agent Exposure
One of the most alarming aspects of the leak is the reported exposure of several undercover agents. While the Department of Homeland Security spokesperson told Fox News that the agency is working to address the situation "swiftly and effectively," the department has not confirmed the exact number of agents compromised or the specific nature of the data leaked regarding these high-risk individuals.
Critical questions remain regarding the entry point of the breach and whether the Department of Peace acted alone or had internal assistance. Furthermore, the Department of Homeland Security has yet to clarify if the 40,000 figre provided by sources is an accurate ceiling or if the breach extends deeper into other agency databases. Until the department releases a full forensic audit, the true risk to field operatives remains unknown.
