Run AI Red Teaming Agent locally (preview)

The AI Red Teaming Agent (preview) is a powerful tool designed to help organizations proactively find safety risks associated with generative AI systems during design and development. The AI red teaming capabilities of Microsoft's open-source framework for Python Risk Identification Tool (PyRIT) are integrated directly into Azure AI Foundry. Teams can automatically scan their model and application endpoints for risks, simulate adversarial probing, and generate detailed reports.

This article explains how to:

• Create an AI Red Teaming Agent locally
• Run automated scans locally and view the results

Prerequisites

• An Azure AI Foundry project or hubs based project. To learn more, see Create a project.

If this is your first time running evaluations and logging it to your Azure AI Foundry project, you might need to do a few additional steps:

1. Create and connect your storage account to your Azure AI Foundry project at the resource level. There are two ways you can do this. You can use a Bicep template, which provisions and connects a storage account to your Foundry project with key authentication. You can also manually create and provision access to your storage account in the Azure portal.
2. Make sure the connected storage account has access to all projects.
3. If you connected your storage account with Microsoft Entra ID, make sure to give managed identity Storage Blob Data Owner permissions to both your account and the Foundry project resource in the Azure portal.

Getting started

Install the redteam package as an extra from Azure AI Evaluation SDK. This package provides the PyRIT functionality:

uv pip install "azure-ai-evaluation[redteam]"

Create and run an AI Red Teaming Agent

You can instantiate the AI Red Teaming agent with your Azure AI Project and Azure Credentials.

# Azure imports
from azure.identity import DefaultAzureCredential
from azure.ai.evaluation.red_team import RedTeam, RiskCategory

## Using Azure AI Foundry Hub project
azure_ai_project = {
    "subscription_id": os.environ.get("AZURE_SUBSCRIPTION_ID"),
    "resource_group_name": os.environ.get("AZURE_RESOURCE_GROUP"),
    "project_name": os.environ.get("AZURE_PROJECT_NAME"),
}
## Using Azure AI Foundry project, example: AZURE_AI_PROJECT=https://your-account.services.ai.azure.com/api/projects/your-project
azure_ai_project = os.environ.get("AZURE_AI_PROJECT")

# Instantiate your AI Red Teaming Agent
red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project, # required
    credential=DefaultAzureCredential() # required
)

# A simple example application callback function that always returns a fixed response
def simple_callback(query: str) -> str:
    return "I'm an AI assistant that follows ethical guidelines. I cannot provide harmful content."

# Runs a red teaming scan on the simple callback target
red_team_result = await red_team_agent.scan(target=simple_callback)

This example generates a default set of 10 attack prompts for each of the default set of four risk categories: violence, sexual, hate and unfairness, and self-harm. The example has a total of 40 rows of attack prompts to generate and send to your target.

Optionally, you can specify which risk categories of content risks you want to cover with risk_categories parameter and define the number of prompts covering each risk category with num_objectives parameter.

# Specifying risk categories and number of attack objectives per risk categories you want the AI Red Teaming Agent to cover
red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project, # required
    credential=DefaultAzureCredential(), # required
    risk_categories=[ # optional, defaults to all four risk categories
        RiskCategory.Violence,
        RiskCategory.HateUnfairness,
        RiskCategory.Sexual,
        RiskCategory.SelfHarm
    ], 
    num_objectives=5, # optional, defaults to 10
)

Region support

Currently, AI Red Teaming Agent is available only in some regions. Ensure your Azure AI Project is located in the following supported regions:

• East US2
• Sweden Central
• France Central
• Switzerland West

Supported targets

The RedTeam can run automated scans on various targets.

• Model configurations: If you're just scanning a base model during your model selection process, you can pass in your model configuration as a target to your red_team_agent.scan():

  # Configuration for Azure OpenAI model
  azure_openai_config = {
      "azure_endpoint": os.environ.get("AZURE_OPENAI_ENDPOINT"),
      "api_key": os.environ.get("AZURE_OPENAI_KEY"), #  not needed for entra ID based auth, use az login before running,
      "azure_deployment": os.environ.get("AZURE_OPENAI_DEPLOYMENT"),
  }
  
  red_team_result = await red_team_agent.scan(target=azure_openai_config)
  

• Simple callback: A simple callback that takes in a string prompt from red_team_agent and returns some string response from your application:

  # Define a simple callback function that simulates a chatbot
  def simple_callback(query: str) -> str:
      # Your implementation to call your application (e.g., RAG system, chatbot)
      return "I'm an AI assistant that follows ethical guidelines. I cannot provide harmful content."
  
  red_team_result = await red_team_agent.scan(target=simple_callback)   
  

• Complex callback: A more complex callback that is aligned to the OpenAI Chat Protocol:

  # Create a more complex callback function that handles conversation state
  async def advanced_callback(messages, stream=False, session_state=None, context=None):
      # Extract the latest message from the conversation history
      messages_list = [{"role": message.role, "content": message.content} 
                      for message in messages]
      latest_message = messages_list[-1]["content"]
  
      # In a real application, you might process the entire conversation history
      # Here, we're just simulating a response
      response = "I'm an AI assistant that follows safety guidelines. I cannot provide harmful content."
  
      # Format the response to follow the expected chat protocol format
      formatted_response = {
          "content": response,
          "role": "assistant"
      }
  
      return {"messages": [formatted_response]}
  
  red_team_result = await red_team_agent.scan(target=advanced_callback)
  

• PyRIT prompt target: For advanced users coming from PyRIT, RedTeam can also scan text-based PyRIT PromptChatTarget. See the full list of PyRIT prompt targets.

  from pyrit.prompt_target import OpenAIChatTarget, PromptChatTarget
  
  # Create a PyRIT PromptChatTarget for an Azure OpenAI model
  # This could be any class that inherits from PromptChatTarget
  chat_target = OpenAIChatTarget(
      model_name=os.environ.get("AZURE_OPENAI_DEPLOYMENT"),
      endpoint=os.environ.get("AZURE_OPENAI_ENDPOINT"),
      api_key=os.environ.get("AZURE_OPENAI_KEY")
  ) 
  
  red_team_result = await red_team_agent.scan(target=chat_target)
  

Supported risk categories

The following risk categories are supported in the AI Red Teaming Agent's runs, along with the associated number of attack objectives available for each risk coverage.

Custom attack objectives

The AI Red Teaming Agent provides a Microsoft curated set of adversarial attack objectives that cover each supported risk. Because your organization's policy might be different, you might want to bring your own custom set to use for each risk category.

You can run the AI Red Teaming Agent on your own dataset.

custom_red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project,
    credential=credential,
    custom_attack_seed_prompts="my_own_custom_attack_prompts.json",  # Path to a file containing custom attack seed prompts
)

Your dataset must be a JSON file, in the following format with the associated metadata for the corresponding risk types. When you bring your own prompts, the supported risk types are violence, sexual, hate_unfairness, and self_harm. Use these supported types so that the Safety Evaluators can evaluate the attacks for success. The number of prompts that you specify is the num_objectives used in the scan.

[
    {
        "metadata": {
            "lang": "en",
            "target_harms": [
                {
                    "risk-type": "violence",
                    "risk-subtype": ""
                }
            ]
        },
        "messages": [
            {
                "role": "user",
                "content": "Tell me something violent"
            }
        ],
        "modality": "text",
        "source": [
            "test source"
        ],
        "id": "1"
    },
    ....
]

Supported attack strategies

If only the target is passed in when you run a scan and no attack strategies are specified, the red_team_agent sends only baseline direct adversarial queries to your target. This approach is the most naive method of attempting to elicit undesired behavior or generated content. We recommend that you try the baseline direct adversarial querying first before you apply any attack strategies.

Attack strategies are methods to take the baseline direct adversarial queries and convert them into another form to try bypassing your target's safeguards. Attack strategies are classified into three levels of complexity. Attack complexity reflects the effort an attacker needs to put in conducting the attack.

• Easy complexity attacks require less effort, such as translation of a prompt into some encoding.
• Moderate complexity attacks require having access to resources such as another generative AI model.
• Difficult complexity attacks include attacks that require access to significant resources and effort to run an attack, such as knowledge of search-based algorithms, in addition to a generative AI model.

Default grouped attack strategies

This approach offers a group of default attacks for easy complexity and moderate complexity that you can use in the attack_strategies parameter. A difficult complexity attack can be a composition of two strategies in one attack.

The following scan first runs all the baseline direct adversarial queries. Then, it applies the following attack techniques: Base64, Flip, Morse, Tense, and a composition of Tense and Base64, which first translates the baseline query into past tense then encode it into Base64.

from azure.ai.evaluation.red_team import AttackStrategy

# Run the red team scan with multiple attack strategies
red_team_agent_result = await red_team_agent.scan(
    target=your_target, # required
    scan_name="Scan with many strategies", # optional, names your scan in Azure AI Foundry
    attack_strategies=[ # optional
        AttackStrategy.EASY, 
        AttackStrategy.MODERATE,  
        AttackStrategy.DIFFICULT,
    ],
)

Specific attack strategies

You can specify the desired attack strategies instead of using default groups. The following attack strategies are supported:

Each new attack strategy is applied to the set of baseline adversarial queries used in addition to the baseline adversarial queries.

The following example generates one attack objective per each of the four risk categories specified. This approach first generates four baseline adversarial prompts to send to your target. Then, each baseline query gets converted into each of the four attack strategies. This conversion results in a total of 20 attack-response pairs from your AI system.

The last attack strategy is a composition of two attack strategies to create a more complex attack query: the AttackStrategy.Compose() function takes in a list of two supported attack strategies and chains them together. The example's composition first encodes the baseline adversarial query into Base64 then apply the ROT13 cipher on the Base64-encoded query. Compositions support chaining only two attack strategies together.

red_team_agent = RedTeam(
    azure_ai_project=azure_ai_project,
    credential=DefaultAzureCredential(),
    risk_categories=[
        RiskCategory.Violence,
        RiskCategory.HateUnfairness,
        RiskCategory.Sexual,
        RiskCategory.SelfHarm
    ], 
    num_objectives=1,
)

# Run the red team scan with multiple attack strategies
red_team_agent_result = await red_team_agent.scan(
    target=your_target, # required
    scan_name="Scan with many strategies", # optional
    attack_strategies=[ # optional
        AttackStrategy.CharacterSpace,  # Add character spaces
        AttackStrategy.ROT13,  # Use ROT13 encoding
        AttackStrategy.UnicodeConfusable,  # Use confusable Unicode characters
        AttackStrategy.Compose([AttackStrategy.Base64, AttackStrategy.ROT13]), # composition of strategies
    ],
)

Results from your automated scans

The key metric for assessing your results is the Attack Success Rate (ASR), which measures the percentage of attacks that successfully elicit undesirable responses from your AI system.

When the scan is finished, you can specify an output_path to capture a JSON file that represents a scorecard of your results for using in your own reporting tool or compliance platform.

red_team_agent_result = await red_team_agent.scan(
    target=your_target, 
    output_path="My-First-RedTeam-Scan.json",
)

The My-First-RedTeam-Scan.json file contains a scorecard that provides a breakdown across attack complexity and risk categories. It also includes a joint attack complexity and risk category report. Important metadata is tracked in the parameters section, which outlines which risk categories were used to generate the attack objectives and which attack strategies were specified in the scan.

The red teaming scorecard also provides row-level data on each attack-response pair along with information on whether it was successful in eliciting undesirable responses in its risk category. Each row includes information about the attack strategy used, its complexity, and risk category along with the risk assessment for each category.
