  • Yonhap News Agency reported the defendant received about 2.9 billion won from CXMT over six years. The court ruled the leaked data constituted protected national core technology, finding the defendant conspired in the breach.
  • Samsung Electronics declined to comment on the verdict, while CXMT did not immediately respond to requests for comment. The Chinese chipmaker previously announced plans to raise $4.33 billion through an initial public offering in Shanghai.
  • The ruling reflects South Korea's enforcement of the Industrial Technology Protection Act to secure critical domestic innovations. Authorities continue investigating security breaches within the semiconductor industry to prevent further unauthorized transfers of national core technology.
