The System Prompt Is the Attack Surface: How LLM Agent Configuration Shapes Security and Creates Exploitable Vulnerabilities
Research reveals that LLM system prompt configuration creates massive security vulnerabilities, with the same model's phishing detection rates ranging from 1% to 97% based solely on prompt design. The study PhishNChips demonstrates that more specific prompts can paradoxically weaken AI security by replacing robust multi-signal reasoning with exploitable single-signal dependencies.
