The Department of Homeland Security (DHS) is investigating a potentially massive data breach that could have exposed the identities and contact information of tens of thousands of employees, sources told Fox News.
The alleged breach, which sources called a “catastrophic” security incident, may have revealed the names, titles, locations and, in some cases, phone numbers and email addresses of about 40,000 DHS employees and contractors, including about 10,000 ICE personnel, according to sources familiar with the data.
The data also includes records associated with more than 20,000 U.S. Customs and Border Protection (CBP) employees, including Border Patrol personnel.
Several sources have confirmed the authenticity of parts of the data.

Data leak website Distributed Denial of Secrets said Wednesday it had leaked employee information.
Fox News has independently confirmed that the leaked documents include the names of several undercover ICE agents working in different parts of the country.
An anti-fascist hacking group calling itself “Department of Peace” claimed responsibility for obtaining the data.
“DHS is aware of a potential violation and is actively working to remedy the situation quickly and effectively,” a department spokesperson told Fox News.

“We take all security threats against our employees and leaders seriously and will ensure that all are properly protected,” the statement continued. “We will update the public when more information becomes available.”
Emma Best, co-founder of Distributed Denial of Secrets, said in a statement that a tool had been developed to allow the public to search the data, saying it would “replace anonymity with accountability.”
The Department of Peace said in its own statement that DHS employees “have our information, so it is only fair that we have theirs” and that it hopes the data “can be used to limit the harm caused by DHS and support all efforts in that direction.”
The reported breach comes amid broader concerns about the security of government personnel records.
