DHS Investigates Major Data Breach Exposing Employee Information

The Department of Homeland Security (DHS) faces an investigation into a serious data breach that potentially exposed the identities and contact details of tens of thousands of its employees. Reports indicate that the incident, described as ‘catastrophic,’ may have revealed the names, job titles, work locations, and in some cases, phone numbers and email addresses of approximately 40,000 DHS employees and contractors. This group includes around 10,000 members of the U.S. Immigration and Customs Enforcement (ICE).

The breach also compromised records for over 20,000 U.S. Customs and Border Protection (CBP) employees, including Border Patrol staff. Several sources have verified parts of the leaked information’s authenticity.

An organization calling itself Distributed Denial of Secrets released the employee information online. Fox News independently confirmed that the leak includes the names of several undercover ICE agents in various regions of the country.

An anti-fascist hacking group known as the ‘Department of Peace’ claimed responsibility for acquiring the data. In response, a DHS spokesperson acknowledged the potential breach and expressed commitment to resolving the situation efficiently and effectively.

The spokesperson stated, ‘We take all security threats against our employees and officers seriously and will work to ensure all are properly protected.’ DHS plans to keep the public informed as more information becomes available.

Emma Best, co-founder of Distributed Denial of Secrets, announced a public tool to search the leaked data, suggesting it would replace anonymity with accountability.

The ‘Department of Peace’ defended its actions, arguing that if DHS has personal data, then they should also share theirs, aiming to minimize potential harm caused by DHS operations.

This event raises broader concerns regarding the security of government staff records. A recent security breach at the Pentagon exposed sensitive personal data of more than 2.76 million U.S. military and civilian personnel, both living and deceased. Officials revealed that unencrypted files with Social Security numbers and job details were accessed by unauthorized users between October 2025 and July 2026.
