Prompt injection exploits LLM bots, revealing sensitive data

Prompt injection, a significant vulnerability in Large Language Models (LLMs) according to OWASP, can be exploited with simple, single-sentence prompts to extract sensitive information like discount codes. Attackers can trick bots into revealing system instructions, internal data, or executing unintended actions by embedding malicious commands within user inputs. Effective mitigation strategies involve not exposing sensitive data directly in prompts, delegating critical decisions to external code, clearly demarcating untrusted data, and rigorously testing outputs for forbidden information.
