Taiwan Proposes National Security Law Reforms After TSMC Data Breach
Taiwan’s Ministry of Justice has proposed amendments to the National Security Act following a high-profile data breach involving Taiwan Semiconductor Manufacturing Company (TSMC). The incident centers on Wei-Jen Lo, a former TSMC senior vice president, who allegedly took sensitive company data reportedly related to sub-2nm chip technology before joining Intel.
The breach has prompted concerns over industrial espionage and technology theft, particularly in Taiwan’s critical semiconductor sector. Authorities are seeking to close legal loopholes to strengthen protections for trade secrets and national security. TSMC has since filed a lawsuit against Lo, underscoring the severity of the alleged leak.
The proposed revisions aim to enhance penalties and enforcement mechanisms for unauthorized data transfers, reflecting growing tensions in global tech competition. The case highlights the risks of insider threats in advanced manufacturing, where proprietary innovations are prime targets for rival firms.
The amendments, if passed, would mark a significant shift in Taiwan’s legal framework for technology protection, with potential implications for foreign collaborations and supply chain security. The incident also coincides with broader industry trends, including AI-driven demand for advanced chips and escalating U.S.-China tech rivalry.
