A previously undisclosed breach at the U.S. Department of Homeland Security has dumped the personal and internal access records of more than 40,000 employees and contractors online, including undercover ICE agents. WIRED and TechCrunch reported on October 28, 2026, that a hacker using the handle Department of Peace provided the data to journalist and hacker maia arson crimew, who shared it with the transparency nonprofit Distributed Denial of Secrets (DDoSecrets). The archive, named "Icepick," was published Wednesday.
The records include names, job titles, work email addresses, cell phone numbers, office locations, and details of which internal systems each person can access. DDoSecrets says the data came from DHS's Okta single sign-on system, though Okta told both outlets it has no evidence its own systems were compromised. The leaked files were last updated on August 19, 2026, and appear to cover about a fifth of DHS's roughly 220,000-strong workforce.
Who was exposed in the DHS data leak
According to WIRED's analysis, Customs and Border Protection staff account for more than half the records, while ICE accounts for around 10,000. USCIS appears with about 6,200 records and CISA with nearly 1,000, more than half of them contractors. The dataset spans DHS itself and seven component agencies, offering a rare map of how the department is organized from senior leadership down to individual immigration agents and detention contractors.
Beyond basic contact details, the leak reveals membership in over 55,000 internal permission groups. Some group names point to sensitive operations, including "CUC" (certified undercover operation), "Keyhole" in HSI's St. Paul, Minnesota, area, a "Title III Intercept Program" for wiretaps, and a "Communications Intercept Center TechOps" program. Others reference tools such as Palantir's Falcon investigative platform, PenLink, and DHS system access groups tied to OpenAI's ChatGPT, Google's Gemini, Microsoft's Copilot, and xAI's Grok chatbot.
