The threat actors gained unauthorized access by breaching the department's single sign-on system in alleged retaliation for remarks made by Markwayne Mullin. The leaked dataset includes more than 21,000 records from Customs and Border Protection alongside roughly 10,000 from Immigration and Customs Enforcement. The stolen materials were transferred to Distributed Denial of Secrets, which published the files under the name Icepick, while independent researchers also hosted a searchable database. Homeland Security officials confirmed they are actively addressing the breach and taking measures to safeguard affected staff.

A hacking group cracked the U.S. Department of Homeland Security's personnel files, exposing the names, phone numbers and addresses of more than 40,000 DHS agents, operatives, and associates, on Wednesday, including those involved in undercover operations.

The hackers said they stole the data by subverting DHS's single sign on system, according to an online post. It said it distributed that material to the group Distributed Denial of Secrets, which posted it online in a database called Icepick. The Department of Peace also shared the trove of data with Ryan Ottignon, a U.S.-based journalist, and a Swiss hacker known as maia arson crimew. Together, the two created a searchable online database, with crimew doing all of the technical work, Ottignon told NPR.

MIT researchers have developed an origami-inspired construction method that transforms flat aluminum sheets into lightweight, rigid structures that can bear loads without interior support columns. The technique uses modular components cut by computer-controlled machines, folded into geometric shapes, and assembled with basic hand tools such as screwdrivers, removing the need for large-scale welding equipment. In a demonstration, the team suspended a 23-foot folded aluminum sculpture in the Boston Public Library at…
