Prompt injection payload library and automated LLM endpoint tester

💉 NullSec PromptInject

Prompt Injection Payload Library & Tester

Curated prompt injection payloads and automated testing for LLM applications

---

🎯 Overview

NullSec PromptInject is a curated library of prompt injection payloads and an automated tester for LLM-powered applications. It targets system prompt extraction, instruction hijacking, context manipulation, and output steering across chatbots, RAG pipelines, AI agents, and function-calling systems.
