(commonly known as Fudan Micro or FMSH). Fudan Microelectronics is a major Chinese semiconductor company specializing in the design, development, and provision of systems solutions for very large-scale integrated circuits (VLSI). The company is publicly traded on the Shanghai Stock Exchange and is a significant player in China's domestic chip industry. The leaked data reportedly includes: - **Internal Documents**: Corporate documentation from the company's operations. - **Schematics**: Circuit designs and technical drawings for integrated circuit products. For a semiconductor company, schematics represent core intellectual property as they contain the detailed design of chip architectures, circuit layouts, and component specifications. - **Intellectual Property**: Broader proprietary technical data beyond schematics, potentially including design specifications, test data, process documentation, and product development materials. The leak of semiconductor schematics and IC design intellectual property from a major Chinese chipmaker carries significant implications. Fudan Micro products are used across smart cards, security chips, RFID, non-volatile memory, and general-purpose microcontrollers. Leaked schematics could enable competitors to reverse-engineer proprietary designs, identify hardware vulnerabilities in deployed chips (relevant for smart card and security chip applications), or gain insight into China's domestic semiconductor capabilities. ## Compromised Data Categories IC Schematics & Circuit Designs Internal Corporate Documents Proprietary Intellectual Property VLSI Design Data Semiconductor Product Details ## Image Preview [![Forum post by s1ic3r leaking 175MB of Shanghai Fudan Microelectronics documents, schematics, and intellectual property with Fudan Micro logo and Free IntelBroker message](https://storage.ghost.io/c/6b/16/6b16ac9c-cd67-432f-b0f3-bbec941084ff/content/images/2026/04/293756782659269579231.png)](https://storage.ghost.io/c/6b/16/6b16ac9c-cd67-432f-b0f3-bbec941084ff/content/images/2026/04/293756782659269579231.png) ## Claim URL Subscriber Access Required The original listing URL and unredacted claim images are available on the Threat Feed and Ransomware Feed for paid subscribers.
