A group of hackers on Wednesday did what the Department of Homeland Security (DHS) has steadfastly refused to do: expose the identities of thousands of federal immigration agents.

The hackers breached a DHS internal database that lists the names, telephone numbers, email addresses and job assignments of employees from Immigration and Customs Enforcement (ICE), Customs and Border Protection (CBP) and other branches of the department. Many of the agents have been involved in highly contentious enforcement and deportation activities during the second Trump administration — including operations that led to the deaths of two U.S. citizens in Minneapolis and several other controversial shootings.

DHS has refused to identify officers, even after they were involved in violent episodes, and agents routinely keep their names secret and wear face masks in public. Although some have been publicly outed through crowdsourcing, the release of the hacked data represents the broadest exposure of the government employees who have carried out President Donald Trump’s aggressive campaign against illegal immigration.

Straight Arrow obtained the data from the Swiss hacker maia arson crimew, who is best known for locating an exposed copy of the U.S. government’s terrorism no-fly list, and the nonprofit leak archiver Distributed Denial of Secrets, known as DDoSecrets. A group calling itself the Department of Peace, or DoP, claimed responsibility for stealing the data from the DHS.

Straight Arrow sought comment from DHS, ICE and CBP, but none immediately responded. DHS officials have defended keeping agents’ identities secret by saying threats against the agency’s employees have multiplied since immigration enforcement intensified after Trump returned to the White House in 2025.
