evidence synthesis on prompt injection resilience testing

Recent studies and practitioner reports indicate that current prompt-injection tests catch direct attacks better than multi-hop tool-mediated exploits (OWASP top ten for llm apps).

evidence stack

• Single-turn tests overestimate real-world resilience.
• Tool invocation paths are a dominant attack surface.
• Defense-in-depth controls outperform single-guard approaches.

method boundary

Meaningful resilience tests must include chained tool use, role confusion, and retrieval poisoning patterns.

my take

Injection testing is maturing, but still underestimates orchestrated attack complexity.
