Taiwan Moves to Tighten National Security Laws After Ex-TSMC Executive Linked to Data Breach

Taiwan is moving to tighten its national security laws after a high-profile incident involving Taiwan Semiconductor Manufacturing Company (TSMC) reignited concerns about the theft of sensitive corporate information and its potential impact on national interests.

The push for change follows a case involving former TSMC senior vice president Wei-Jen Lo, who allegedly took confidential company data. The situation has drawn attention not only because TSMC is one of Taiwan’s most strategically important companies, but also because semiconductor know-how, business intelligence, and advanced manufacturing details can carry national-level security implications in today’s global tech race.

In response, Taiwan’s Ministry of Justice has proposed revisions to the National Security Act aimed at strengthening protections and closing legal gaps that can make it difficult to prosecute or deter the misuse of critical data. The proposed amendments are designed to better address modern threats, where valuable information can be copied quickly, transferred digitally, and potentially leveraged by outside entities in ways that harm Taiwan’s competitiveness and security.

The move reflects a broader reality: semiconductor technology is no longer just a business asset—it’s a pillar of economic resilience and a key factor in geopolitical stability. When sensitive chip-related information is exposed or removed, the risk extends beyond a single company’s intellectual property. It can affect supply chain integrity, technological leadership, and Taiwan’s position in the global semiconductor industry.

By updating the National Security Act, the government is signaling a tougher stance on the protection of critical technologies and trade secrets. The goal is to increase deterrence, improve enforcement tools, and ensure that cases involving strategically significant data don’t fall into loopholes that weaken accountability.

As global competition for advanced chip manufacturing intensifies, Taiwan’s proposed legal revisions underscore a clear message: safeguarding high-value technology and sensitive corporate data is now a national priority, and the legal framework must evolve to match the scale and speed of modern information threats.
