The personal details of more than 41,000 employees of the US Department of Homeland Security (DHS) have been made public after a leak, including thousands of staff involved in immigration enforcement. The information was posted online and includes names, work addresses and phone numbers, along with descriptions of each person’s duties at their agency. The leak was published on Wednesday and is the third time in recent weeks that a US government agency has been targeted by a leak or hack.
A DHS spokesperson said the department is aware of a possible breach and is working quickly to deal with it. The spokesperson said the department takes threats against its staff seriously and intends to make sure they are properly protected. The department also said it would give the public an update once more information becomes available.
What the leaked records show about DHS staff
The data covers staff at several DHS components, including agents working for Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP). According to the records, more than 21,000 of the people listed work for CBP, and nearly 6,600 work for ICE. Other entries belong to staff at Homeland Security Investigations, the Federal Protective Service and the Cybersecurity and Infrastructure Security Agency.
The material also includes dozens of operation names that had not previously been public, along with the agents who led and worked on them. It further lists some of the technology the staff used in their jobs, including tools supplied by Cellbrite and Palantir.

Hackers claim access through a single sign-on service
A group calling itself the Department of Peace said it obtained the agent profiles from DHS through a single sign-on service called Okta. Journalist and cybersecurity researcher maia crimew, together with the website Distributed Denial of Secrets (DDoSecrets), then placed the information online. The data was organised in a database named Icepick.
Okta is a widely used online security tool that organisations rely on to confirm that only authorised people can log in to their internal platforms. A spokeswoman for Okta said the company was aware of the claims. She added that the company was secure and had no evidence that its data or systems had been compromised.
DDoSecrets and the group said in an online statement that the release was not intended to be a complete list of every DHS agent. Instead, they said the aim was to replace anonymity with accountability. Emma Best, a co-founder of DDoSecrets, said the leak identifies officials who oversee covert and undercover operations, people involved in the government’s hunt for leakers, and figures connected to the failed BlueLeaks investigation. She also said it identifies key personnel in DHS’s expanding rendition and deportation programmes.
BlueLeaks refers to a large 2020 leak of US police data, some of which DDoSecrets also hosted. The Department of Peace’s spokesperson linked the group’s hacking of DHS records to actions taken by ICE agents. The spokesperson wrote on Wednesday that Markwayne Mullin had said on July 17 that he was “turning up the heat”, and that this was what happens to ICE when he did so. Mullin became Secretary of Homeland Security in March.
Wider pressure over breaches and immigration enforcement
The DHS leak follows other recent security incidents. Last month, the FBI was hacked by a group called ShinyHunters, which took personal information about thousands of agents. In recent days, the Federal Election Commission, which publishes data on political campaign donations, was taken offline after a suspected hacking attempt.
The leak also comes as public anger over US immigration enforcement grows. The Trump administration has pushed for a large 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 at more than two dozen people and killing at least nine.
Among those killed were Alex Pretti and Renee Good, who were shot dead by ICE agents in Minnesota this year, although neither was the target of an arrest. ICE agents often carry out operations with their faces covered by masks and sunglasses. Immigration agents rarely identify themselves, even though the law requires it, and US politicians have publicly demanded that DHS enforce that requirement.
Since Donald Trump returned to office in 2025, the US has carried out nearly one million deportations, according to data from the Migration Policy Institute. More than 70% of those deported had no criminal record, the institute’s data shows.
