A group calling itself the Department of Peace posted names, work addresses and phone numbers of more than 41,000 U.S. Department of Homeland Security employees on Wednesday, the BBC reported, including staff at Immigration and Customs Enforcement and Customs and Border Protection¹.

The BBC said the material was placed in a database named Icepick and shared through a site hosted by Distributed Denial of Secrets, alongside cybersecurity researcher maia crimew¹. DHS did not immediately respond to the BBC¹.

According to the BBC, most of the listed personnel, more than 21,000, were identified as CBP staff, and nearly 6,600 as ICE staff, with other records described as covering Homeland Security Investigations, the Federal Protective Service and the Cybersecurity and Infrastructure Security Agency¹.

The Department of Peace said it reached DHS agent profiles through Okta, a single sign-on service used to control access to internal systems, according to the BBC¹. An Okta spokeswoman told the BBC the company was aware of the claims¹. "Okta is secure, and we have no evidence our data or systems were compromised," the spokeswoman said¹.

Emma Best, a co-founder of DDoSecrets, told the BBC the aim was not a full directory of every DHS agent and described the goal as replacing anonymity with accountability¹. Best also said the dump identified officials tied to covert work, leak investigations and deportation programs, according to the BBC¹.

The BBC said the leak was the third time in recent weeks a U.S. government agency had been targeted in leaks or hacks, citing a reported FBI breach last month attributed to a group called ShinyHunters and a suspected hacking attempt that recently took the Federal Election Commission offline¹.

Whether the posted records are complete or accurate, how they were obtained, and what DHS or law enforcement will do next were not established in the BBC account¹.
