This entry refers to the unauthorized access and exfiltration of LLM models by malicious actors or APTs. This arises when the proprietary LLM models (being valuable intellectual property), are compromised, physically stolen, copied or weights and parameters are extracted to create a functional equivalent. The impact of LLM model theft can include economic and brand reputation loss, erosion of competitive advantage, unauthorized usage of the model or unauthorized access to sensitive information contained within the model.
