LLM Exploitation

The article details a precision prompt injection attack methodology against AI agents, using a fictional travel agent called 'Varda' as a case study. The attack follows a kill chain approach: reconnaissance to extract system prompt logic, enumerate tools, and learn data schemas; then weaponization to craft a fake payment confirmation that satisfies the agent's preconditions for booking flights. The core vulnerability is that the LLM treats conversation history as trusted context, allowing attackers to inject fabricated tool responses and fake assistant messages that bypass sequential validation checks, enabling unauthorized action execution without proper authorization.
