Hackers leak names of 41,000 US Homeland Security employees, group claims

Gulfnews • October 29, 2026

Washington: A nonprofit news leak group said Wednesday it has published data on more than 41,000 employees of the US Department of Homeland Security, including those working on President Donald Trump's immigration enforcement efforts.

Distributed Denial of Secrets (DDOS) said it obtained the sensitive information from a "hacktivist group" known as the Department of Peace, which created a tool named Icepick that facilitates detailed searches of employee names, offices and assignments.

"This dataset is massive in terms of both size and impact," an associated activist, Maia Arson Crimew, said in a DDOS statement.

"It provides an unprecedented look into the Department of Homeland Security's organizational structure, highlighting which people do what work across multiple DHS agencies, including ICE," the activist said, refering to US Immigration and Customs Enforcement.

DHS and ICE have been at the center of an immigration crackdown ordered by Trump at the start of his second term, in January 2025.

DDOS cofounder Emma Best called the leak "extraordinary."

The data "identifies the officials responsible for overseeing covert and undercover operations, the government's hunt for leakers...along with key personnel in DHS's ever-escalating rendition and deportation programs."

The crackdown has seen thousands of undocumented people detained and deported, while US citizens have also been caught up in the dragnet.

Last month DHS said it was initiating a "surge in sanctuary cities" - which are known to limit cooperation between local law enforcement and federal authorities - as the Trump administration ramped up its crackdown on immigration.

The non-partisan Migration Policy Institute said in a fact sheet that Trump's DHS has expanded its arrests and deportations over the last several months, outpacing the immigration enforcement efforts of his predecessor Joe Biden.

It said DHS, including ICE, "completed 980,000 deportations" in the first 18 months of the second Trump presidential term.

Massive Data Leak Exposes 41,000 DHS Employees A hacktivist group called the Department of Peace leaked personal data of over 41,000 employees from the U.S. Department of Homeland Security (DHS), including Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) agents. The data, named 'Icepick', was obtained from an Okta single sign-on service used by DHS and includes names, job titles, phone numbers, and email addresses. The breach represents about one-fifth of DHS's workforce and reveals sensitive information about undercover operations and surveillance tools. DHS confirmed awareness of the breach and is working to address it, while Okta stated it found no evidence of a compromise in its systems. The leak is seen as a response to intensified enforcement actions by DHS Secretary Markwayne Mullin. This incident follows other recent breaches affecting U.S. federal agencies. 66 sources 65
