Dark Web Market Lists Alleged 375TB Lockheed Martin Data

Hackers claiming to have stolen 375 terabytes of data from Lockheed Martin are selling the material on a dark web marketplace. On March 26, 2026, a Telegram account tied to the Threat Market posted that a group identified as APT IRAN had approached the platform for infrastructure support to sell the alleged data. The account stated that the group received direct access to the administrative panel and referenced the use of cryptocurrency mixers to handle proceeds. On March 29 the same account announced that the full 375TB dataset had been listed for sale. The listing described a complete dump with a stated value of roughly 374 million dollars and an exclusive buyout price near 600 million dollars. Screenshots from the marketplace, analyzed by Hackread.com, showed categorized segments that referenced internal projects, source code, and personnel information. The structure matched typical dark web data sale pages, though the authenticity of the material remains unconfirmed. Claims of large breaches involving hundreds of terabytes appear regularly on dark web markets, where figures are often presented to draw attention. A buyout price at this level has not been seen before. Lockheed Martin has not confirmed any breach. No sample data has been verified by security researchers. Hackread.com has contacted the company for comment.
