LLM Credential Theft

LLM credential theft refers to attacks targeting large language models to extract sensitive authentication data, API keys, or user credentials embedded in training data or accessible through model inference. This poses significant governance and compliance risks because stolen credentials can lead to unauthorized access to enterprise systems, data breaches, and violation of security standards like SOC 2 and ISO 27001. Organizations must implement strict data handling policies, credential detection mechanisms, and prompt injection defenses to prevent LLMs from inadvertently exposing or leaking sensitive authentication information.
