10 Aug
Summary
- Former SK Hynix employee received an 18-month jail sentence.
- The sentence was for leaking classified semiconductor technology.
- Information was leaked to an unnamed Chinese firm in 2022.

A former employee of SK Hynix has been sentenced to 18 months in prison for leaking sensitive semiconductor manufacturing technology to a Chinese company. The Seoul High Court confirmed the sentence, ruling that the individual had violated security protocols.
The employee, who previously worked for SK Hynix in China, was found to have printed or photographed documents containing trade secrets. This information, downloaded from the company's internal servers, was then disclosed in a resume submitted to a Chinese firm in 2022.
During the appeal, the court upheld the lower court's decision. The defendant has admitted to all charges. Most of the stolen proprietary information has since been recovered by SK Hynix.
