LLM scam detector fooled by fake reviewer note, highlighting prompt injection risks

A developer demonstrated a vulnerability in an LLM-based scam detector where a prompt injection attack successfully fooled the system. The model not only made an incorrect decision but also fabricated a justification for its error, mimicking the attacker's fabricated reviewer note. This highlights that prompt-level fixes can degrade a model's core judgment, and a more robust solution involves code-level input validation outside the LLM itself, similar to traditional application security practices.
