DHS Leak Exposes Data on 41,000 Immigration and Border Agents

Publicly available data now contains the names, work addresses, and phone numbers of more than 41,000 employees at the US Department of Homeland Security. The records, made public on Wednesday, focus on personnel involved in immigration enforcement and border security. The dataset includes specific details for agents working with Immigration and Customs Enforcement and Customs and Border Protection.

According to the leaked files, more than 21,000 of the listed individuals work for Customs and Border Protection. Nearly 6,600 are identified as agents for ICE. The remaining records cover staff from Homeland Security Investigations, the Federal Protective Service, and the Cybersecurity and Infrastructure Security Agency. The data also lists dozens of operation names and identifies the technology used in those operations, including systems provided by Cellbrite and Palantir.

A group calling itself the Department of Peace stated it accessed the information through Okta, a single sign-on service used by organizations to manage internal logins. The group partnered with journalist and cybersecurity researcher maia crimew and the website Distributed Denial of Secrets to publish the data in a database named Icepick. A spokeswoman for Okta said the company is aware of the claims but maintains that its data and systems were not compromised.

Emma Best, a co-founder of Distributed Denial of Secrets, said the goal was not to create a directory of every agent. Instead, the group aimed to replace anonymity with accountability. Best noted that the leak identifies officials responsible for overseeing covert operations and the government's hunt for leakers. She also pointed to key personnel in DHS's rendition and deportation programs.

The Department of Peace cited specific actions by ICE as motivation for the hack. A spokesperson for the group referenced a July 17 statement by Markwayne Mullin, who became Secretary of Homeland Security in March. The spokesperson wrote that the leak is a direct response to Mullin saying he was turning up the heat on the agency. The group linked the breach to the administration's aggressive enforcement posture.

This incident is the third recent security failure at a US government agency. Last month, a group called ShinyHunters hacked the FBI and obtained personal information on thousands of agents. In recent days, the Federal Election Commission was taken offline following a suspected hacking attempt. The FEC is responsible for making public political campaign donation data.

Public scrutiny of immigration enforcement has intensified as the Trump administration increases arrests and deportations. Data from the Migration Policy Institute shows the US has enacted nearly 1 million deportations since President Donald Trump returned to office in 2025. More than 70 percent of those deportations involved people with no criminal record. Operations this year have resulted in violence, with ICE agents shooting at more than two dozen people and killing at least nine.

Those fatalities include Alex Pretti and Renee Good, both of whom were shot and killed by ICE agents in Minnesota this year despite not being the targets of arrests. Agents often perform enforcement actions while wearing masks and sunglasses. They rarely identify themselves, even though they are required by law to do so. Politicians have publicly demanded that DHS enforce this identification requirement.

A DHS spokesperson said the agency is aware of a potential breach and is working to address it swiftly. The spokesperson stated that the department takes security threats against employees seriously and will ensure they are protected. The agency said it will update the public when more information is available.
