Details of thousands of US immigration agents leaked in major hack

US immigration agents often operate with their faces covered and without visible identification.

Information on more than 41,000 employees of the US Department of Homeland Security (DHS), including thousands involved in immigration enforcement, has been leaked publicly.

The leak contains names, work addresses and phone numbers of DHS personnel, including agents with Immigration and Customs Enforcement (ICE) and Customs and Border Protection, as well as descriptions of the work they perform for each agency.

Wednesday’s leak is the third time in recent weeks that a government agency has been hit by a leak or hack.

A DHS spokesperson said the department is "aware of a potential breach and is actively working to address the situation swiftly and effectively."

"We take all security threats against our employees and officers seriously and will work to ensure all are properly protected," the spokesperson added.

"We will update the public when more information is available."

The apparently unprecedented exposure of employee data was published online. A group called the Department of Peace obtained the information from DHS, while journalist and cybersecurity researcher maia crimew, together with the website Distributed Denial of Secrets, posted it online.

The data was organized in a database called Icepick.

According to the data, most of the agents listed — more than 21,000 — work for CBP. Nearly 6,600 work for ICE.

Other records identify agents with Homeland Security Investigations, the Federal Protective Service and even staff working for the Cybersecurity and Infrastructure Security Agency.

The leaked material also included dozens of previously unknown operation names, the agents who led and worked on those operations, and some of the technology used in their work, including tools from Cellbrite and Palantir.

In an online statement, the groups said the leak was not intended to serve as a directory of every DHS agent. Instead, the goal was to replace "anonymity with accountability", according to Emma Best, a co founder of DDoSecrets.

"The leak is extraordinary but deceptive in its simplicity as it identifies the officials responsible for overseeing covert and undercover operations, the government's hunt for leakers and the failed BlueLeaks investigation - along with key personnel in DHS's ever-escalating rendition and deportation programs," Best added.

BlueLeaks refers to a huge 2020 leak of US police data, which DDoSecrets also hosted.

A spokesperson for the Department of Peace directly linked the group’s hacking of DHS records to ICE agents’ actions.

"On July 17th, Markwayne Mullin said he was 'turning up the heat'. This is what happens to ICE when you do that," the spokesperson wrote on Wednesday.

Mullin in March became Secretary of Homeland Security.

The Department of Peace said it accessed the DHS agent profiles through a single sign-on service called Okta.

Okta is a widely used online security tool that organizations use to make sure only authorized people can log in to internal platforms.

A spokeswoman for Okta said the company is aware of the allegations, but added: "Okta is secure, and we have no evidence our data or systems were compromised."

Last month, the FBI was hacked by a group called ShinyHunters, which stole personal information on thousands of agents.

In recent days, the Federal Election Commission, which publishes political campaign donation data, was taken offline after a suspected hacking attempt.

Public anger over US immigration enforcement has been growing as the Trump Administration has pushed a major rise in arrests and deportations of people suspected of being in the country illegally.

Immigration operations this year have repeatedly turned violent, with ICE agents shooting more than two dozen people and killing at least nine.

Those deaths include the high profile killings of Alex Pretti and Renee Good, both of whom were shot and killed by ICE agents this year in Minnesota, despite not being the targets of arrests.

ICE agents often carry out enforcement actions with their faces covered by masks and sunglasses. Immigration agents rarely identify themselves, even though they are required by law to do so, and US politicians have publicly demanded DHS enforce that requirement.

Since President Donald Trump returned to office in 2025, the US has carried out nearly 1 million deportations, according to data from the Migration Policy Institute. More than 70% of those deportations involved people with no criminal record.
