Samsung engineers leak semiconductor source code to ChatGPT
What happened
Within weeks of Samsung permitting ChatGPT use, engineers pasted proprietary semiconductor source code and internal meeting transcripts into the chatbot on at least three occasions — submitting database source code to check for errors, uploading defect-detection code for optimization, and feeding in recorded meeting notes for summarization.
Impact
Samsung banned generative AI tools company-wide in May 2023 after confidential semiconductor IP was irrecoverably transmitted to a third-party service.
How this could have been prevented
DLP controls that scan and block sensitive code and documents in prompts — plus sanctioned enterprise LLM deployments — prevent employee-driven leakage.
