According to TechCrunch, a hacker identifying as "Department of Peace" claimed to have obtained a large volume of employee data from the Okta single sign-on system used by the U.S. Department of Homeland Security (DHS). The data was publicly released Wednesday as the "Icepick" dataset by transparency organization Distributed Denial of Secrets (DDoSecrets). The leaked records number over 40,000, roughly one-fifth of DHS’s approximately 220,000 employees. The data includes names, job titles, work emails, phone numbers, office locations, and internal system access permissions. Among the records, around 21,000 belong to Customs and Border Protection (CBP) staff, roughly 10,000 relate to Immigration and Customs Enforcement (ICE) and Homeland Security Investigations (HSI), and nearly 1,000 are from the Cybersecurity and Infrastructure Security Agency (CISA). TechCrunch said it verified the authenticity of some data, with timestamps indicating the data was exported around mid-August. The hacker also provided the data to journalist and hacker maia arson crimew, who then forwarded it to DDoSecrets. Okta responded that its systems and data were not breached; a DHS spokesperson did not immediately reply to a request for comment. The report notes this is the third high-profile U.S. government data breach in the past month, following earlier thefts of FBI personnel files and Pentagon personnel data.

According to Reuters, the U.S. Department of Justice (DOJ) has launched an investigation into Nvidia’s acquisition of open-source AI model platform Hugging Face, focusing on its impact on AI competition and Nvidia’s business practices. Citing two people familiar with the matter, Reuters reported that DOJ officials have questioned whether the roughly $129 billion deal would give Nvidia control over a critical distribution hub in the AI sector, and whether Nvidia could use Hugging Face to harm competitors or leverage it as a bargaining chip. Officials also raised questions about Hugging Face’s rivals. The sources said the DOJ’s recent broad investigation covers Nvidia’s acquisitions and investments, sales practices, and whether the company pressures customers. The probe began under the Biden administration and has continued into the Trump administration; Reuters noted there is no indication that Trump is involved. Separately, the DOJ is also examining whether, after obtaining technology licenses from chip startup Groq and hiring its core engineers, Nvidia allocated more AI chips to customers that purchased both networking equipment and Groq processors. The SchedMD acquisition announced in December 2025 and the Run:ai acquisition have also come under scrutiny. Reuters emphasized that an investigation does not constitute evidence of wrongdoing and does not necessarily lead to litigation. When Nvidia announced its Hugging Face acquisition last month, it stated that the platform would continue to support partnerships with all types of semiconductor, cloud, and AI vendors, and remain open to the entire AI ecosystem. The deal is expected to close in the first half of next year.
