Azure OpenAI Red Team Walkthrough
Complete red team walkthrough for Azure OpenAI deployments: testing content filters, managed identity exploitation, prompt flow injection, data integration attacks, and Azure Monitor evasion.
Azure OpenAI Service wraps OpenAI models (GPT-4, GPT-4o, o1, DALL-E, Whisper) in Azure's enterprise infrastructure. This adds Entra ID (formerly Azure AD) authentication, Azure AI Content Safety filtering, Virtual Network integration, Prompt Flow orchestration, and On Your Data (RAG) capabilities. Each layer introduces attack surface not present when using the OpenAI API directly.
This walkthrough covers structured red team testing of production Azure OpenAI deployments, building on the introductory walkthrough with advanced attack techniques.
Phase 1: Deployment Reconnaissance
Enumerating Resources
Start by mapping all Azure OpenAI resources, deployments, and their configurations.
# azure_recon.py

Azure AI Content Safety provides configurable content filtering with severity levels (0-6) across categories: Hate, Self-Harm, Sexual, Violence, and a Jailbreak risk category. Content filters are configured per-deployment.

Azure OpenAI's "On Your Data" feature connects models to Azure AI Search, Azure Blob Storage, and other data sources for RAG. This creates data exfiltration attack surfaces similar to Bedrock Knowledge Bases but with Azure-specific characteristics.

Azure Prompt Flow is a visual orchestration tool for building LLM pipelines. When applications use Prompt Flow, the flow definition becomes part of the attack surface.
