South Korea Expands Spy Prevention Law to Protect Semiconductor Technology

South Korea has enacted a major expansion of its spy prevention law for the first time in over 70 years, which took effect on September 13. The revised legislation introduces severe penalties, including prison sentences of up to 30 years for individuals who disclose sensitive information to foreign organizations or entities. This legislative change is a direct response to a notable increase in cases of technology theft, particularly concerning the semiconductor sector, which is crucial for South Korea's economic stability.

Previously, the law was narrowly defined, primarily targeting information transferred to what was classified as enemy states, effectively focusing on North Korea. However, the new provisions broaden the scope to encompass any foreign entity, reflecting the growing concerns over espionage activities, particularly from China. Reports indicate that incidents of technology leakage have surged, prompting urgent calls for stronger protective measures.

The South Korean government has recognized the semiconductor industry as a strategic asset, with major players like Samsung and SK Hynix frequently targeted for their proprietary technologies. According to the National Police Agency, there were 33 reported cases of technology leakage to foreign entities in 2025, with more than half linked to China. This alarming trend has underscored the necessity for enhanced legal frameworks to safeguard national interests.

Case Closed

Experts in the field, such as Kwon Seok-jun from Sungkyunkwan University, have highlighted the vulnerabilities posed by former employees and senior engineers who may be lured by lucrative offers from foreign companies. Kwon noted that these individuals are often approached with salaries two to three times higher than their previous earnings, creating a significant risk for information breaches. The law aims to deter such activities by imposing strict penalties on those who facilitate the transfer of sensitive technologies.

As South Korea continues to navigate the complexities of global technology competition, the expanded spy prevention law represents a critical step in fortifying its defenses against foreign espionage. The government is committed to ensuring that the country's technological advancements remain secure and that its competitive edge in the semiconductor market is preserved.
