Personal and professional data of more than 41,000 US Department of Homeland Security ( DHS, including thousands of immigration law enforcement agents, have been published online after a major cyber security incident.
The resulting information includes names, working addresses, phone numbers and descriptions of the offices of agencies such as the Migration and Customs Service ( ICE) and Customs and Border Protection ( CBP), transmitsgraphy.
A spokesman for The DHS stated that the institution is aware of a possible security breach and is working to address the situation. We take seriously all threats against our employees and officials and we will make sure that they are properly protected, he said, adding that the public will be informed when there are more details.
The data was released on Wednesday on a base called Icepick. According to reports, information was provided by a group calling itself the Department of Peace, while cyber security journalist and researcher maia crimew and the Dicret-Distributed Denial platform ( DDoSecrets helped publish them.
According to the database, more than 21,000 of the people involved work for CBP, while approximately 6,600 are part of ICE. The data also includes workers of Homeland Security Investments, the Federal Service for Protection and the Agency for Cyber Security and Infrastructure.
In addition to employee data, publication contains names of operations that had not been made public before, information about agents who conducted or participated in them, as well as some of the technologies used, including tools provided by Cellbrate and Palatir.
Representatives of the groups involved said the goal was not to create a full list of every DHS agent, but to increase accountability. Emma Best, co-founder of DDoSecrets, said the publication highlights officials responsible for monitoring secret operations, investigating persons who reveal confidential information and expulsion programmes.
A Department of Peace spokesman linked the action to the activities of ICE agents. He referred to a statement by Secretary of Homeland Security Markway Mullin on July 17, when he said he was getting pressure on the agency. Mullin took office as secretary in March.
According to the Department of Peace, employee profiles were provided through the centralised Okta identification and entrance service used by organisations to control access to internal platforms. A company spokeswoman said Okta is aware of the claims, but that there is no evidence that its systems or data have been compromised.
The incident comes after several other cyber security cases affecting American institutions. Last month, the ShinyHunters group attacked the FBI and received personal information from thousands of agents. In the past few days, the Federal Election Commission was removed from office due to an alleged cyberattack attempt.
The flow of data occurs in a period when public opposition to immigration operations in the US has increased, while President Donald Trump’s administration has expanded the arrests and expulsions of persons allegedly illegally located in the country.
During this year, several immigration operations have ended with violence. According to the report, ICE agents have shot at more than two dozen people and killed at least nine. Among the victims are Alex Pretti and Renee Good, who were shot to death by ICE agents in Minnesota, although there were no targets of arrests.
Migration agents often perform operations with faces covered by masks and glasses, while American politicians have demanded that the DHS implement the legal obligation to identify them.
According to Migration Policy Institute data, since Trump’s return to the White House in 2025, the U.S. has accomplished nearly a million expulsions. More than 70 percent of those expelled, according to the same source, had no penal precedents. /Telegraphy/
