GeminiJack Challenge

Challenge Overview

Exploit a vulnerable RAG-based AI assistant by injecting malicious calendar events. Your goal is to craft payloads that exfiltrate data when the AI processes user queries.

Prompt Injection LLM Security RAG Exploitation

Quick Start

Two interfaces simulate the attack scenario:

Outlook Client Google Gemini Leaderboard

Outlook Client — Submit malicious calendar events (attacker interface)
Google Gemini — Query the vulnerable AI assistant (victim interface)
Leaderboard — Track successful attacks and player rankings

How It Works

1. Submit a calendar event via the Outlook Client
2. Query the AI assistant in Google Gemini about calendar or meetings
3. If successful, data will be exfiltrated to your URL

Rules

Use https://geminijack.securelayer7.net/exfil?data=YOUR_DATA for exfiltration to track wins
Submit unlimited payload attempts
Collaboration and knowledge sharing encouraged
Do not attack the infrastructure or other participants

Research: Based on GeminiJack vulnerability research affecting AI systems using RAG.
