Supplier hit by 70GB data sale
Sekisui Aerospace, a tier‑one supplier to Boeing, NASA, Lockheed and Northrop, was targeted in a large data exfiltration incident with reports of a 70GB data sale linked to the breach. The alert flagged potential exposure across multiple prime-supplier relationships. (brinztech.com)
A cybercrime post is offering 70 gigabytes of alleged Sekisui Aerospace data, including export-controlled aircraft files, for $200,000. (darkwebinformer.com) Dark Web Informer said the listing appeared April 13, 2026 and attributed it to a threat actor using the name “nxe.” The post described engineering drawings, STEP computer-aided design files, bills of materials with Boeing part numbers, and tooling data tied to Boeing 737 Max and 787 work. (darkwebinformer.com) Sekisui Aerospace says it has more than 1,000 employees, more than 500,000 square feet of manufacturing space, and operations in Renton, Sumner, and Orange City. The company says it designs and manufactures composite aerospace parts and has worked in the sector for more than 30 years. (sekisuiaerospace.com) The alleged files matter because they are described as technical blueprints and production data, not a list of names or passwords. Sekisui says it is a Boeing-approved Digital Product Definition supplier, a designation tied to the controlled handling of digital engineering data. (sekisuiaerospace.com) The sales post says the package is marked “EAR 9E991 / ITAR Technical Data,” a label used for export-controlled aerospace information. Brinztech reported a similar Sekisui-related dark-web listing on November 21, 2025, when it described a 53 gigabyte database offered for $75,000. (darkwebinformer.com) (brinztech.com) That means the current 70 gigabyte sale claim may be a resale, a larger repackaging, or a separate tranche of the same haul; the public posts do not resolve which. Dark Web Informer said the seller claimed the data had been sold to them previously as a one-time deal and was now being resold. (darkwebinformer.com) (brinztech.com) Sekisui’s own materials describe the company as a maker of primary structures, thermoplastic components, assembly work, and inspection services for commercial aerospace and defense programs. Its site also says it uses automation, machining, bonding, and non-destructive inspection across production and quality control. (sekisuiaerospace.com 1) (sekisuiaerospace.com 2) Boeing’s supplier portal says the company relies on a global network of supplier partners, which is why a breach at a component maker can ripple beyond one factory. Sekisui’s site does not show a public breach notice or incident statement in the pages indexed as of April 14, 2026. (boeingsuppliers.com) (sekisuiaerospace.com) For now, the public record shows a criminal sales claim and a supplier whose business sits deep inside aerospace manufacturing. What happens next depends on whether Sekisui, its customers, or federal authorities confirm the files are authentic and complete. (darkwebinformer.com) (sekisuiaerospace.com)
