Hellsender01/README.md

Security researcher who enjoys poking at systems that were never meant to break.

Lately I have been spending most of my time exploring AI and LLM security. This includes prompt injection, agent based systems and red teaming language models.

What I am working on

  • LLMMap
    An automated prompt injection testing framework for LLM-integrated applications, inspired by sqlmap. Discovers injection points in HTTP requests, generates targeted payloads using a dual-LLM architecture and confirms findings with statistical reliability testing. Covers 227 prompt injection techniques across 18 attack families with support for Ollama, OpenAI, Anthropic and Google backends. LLMMap

  • Prompt Injection Taxonomy
    253 prompt injection techniques organized into 17 attack categories with mapping to the OWASP LLM Top 10.
    Prompt Injection Taxonomy

  • Researching attack surfaces in agent based AI systems and RAG pipelines
