SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical need to identify and validate vulnerabilities in LLM-integrated applications, such as prompt injection, indirect injection, and insecure tool usage, which are often missed by traditional security scanners.

Core Features & Use Cases

  • Injection Validation: Detects direct and indirect prompt injection vulnerabilities across chatbots, RAG systems, and agentic copilots.
  • Exfiltration Testing: Provides methodologies to verify OOB exfiltration via markdown images, tool-use, and DNS-only channels.
  • Agentic Security: Evaluates OWASP Agentic Apps (ASI01-ASI10) risks, including memory poisoning and tool parameter injection.

Quick Start

Use the hunt-llm-ai skill to probe the target chatbot for prompt injection vulnerabilities by sending a verbatim-reproducible system-prompt extraction payload.

FAQPage Schema
How do I test chatbots for prompt injection vulnerabilities?

To test chatbots for prompt injection vulnerabilities, use targeted payloads to probe for direct and indirect injection flaws. This process validates whether the target system is susceptible to system-prompt extraction or unauthorized instruction overrides.

What is indirect prompt injection in RAG pipelines?

Indirect prompt injection in RAG pipelines occurs when malicious instructions are embedded within retrieved data sources. Attackers exploit this to manipulate the LLM's behavior by injecting payloads into untrusted documents that the pipeline processes.

How do I verify OOB data exfiltration in LLM applications?

Verify OOB data exfiltration in LLM applications by triggering markdown image callbacks, tool-use execution, or DNS-only channels. Proving impact requires an OOB callback or verifiable data leak to confirm the vulnerability exists.

Can I test autonomous agents for insecure tool-use primitives?

Yes, you can test autonomous agents for insecure tool-use primitives. This involves evaluating agentic security risks like tool parameter injection and memory poisoning to validate potential impact and verify unsafe execution paths.

How do I distinguish actual LLM security flaws from model confabulation?

Distinguish actual LLM security flaws from model confabulation by enforcing a False-Positive Gate. This required validation mechanism ensures reported vulnerabilities are verified through reproducible payloads rather than hallucinated model outputs.

What is the best way to pentest AI security flaws?

The best way to pentest AI security flaws is to target chatbots, RAG pipelines, and autonomous agents with verifiable exploitation methods. This approach validates injection vectors and insecure tool usage while proving impact through data leaks.
