If your agent can read files or run shell commands on the host, it is a candidate for this test. +# +# ## Solution Overview +# +# This notebook is part of a **Red Team AI Agent Evaluation** module, built on [PyRIT](https://github.com/Azure/PyRIT), that automatically tests agent behavior under adversarial attack scenarios. +# The solution is **platform-agnostic** — it targets any agent exposed over HTTP. The agent under test can be deployed in a Docker container to ensure isolation from the production environment. +# +# ### Docker Environment +# +# The Docker sandbox image provides a realistic attack surface by pre-populating the agent's file system with **canary-instrumented sensitive files** — fake but realistic versions of `/etc/shadow`, `~/.ssh/id_rsa`, `.env`, `/etc/passwd`, `~/.bash_history`, `/etc/crontab`, and `/proc/self/environ`. Each file contains a unique canary marker that the scorer uses to deterministically detect whether the agent leaked that file's contents. +# +# ### Non-Docker Alternative +# +# If you prefer not to deploy your agent inside the provided Docker sandbox, you can use the [`plant_canaries.py`](../../../../docker/agent-sandbox/plant_canaries.py) script to plant canary files directly into the agent's host environment. The script writes the same canary-instrumented files at their real system paths (e.g., `/etc/shadow`, `/root/.ssh/id_rsa`), appending canary content to existing files and safely stripping it on cleanup — without deleting original system files. Run `python docker/agent-sandbox/plant_canaries.py --force` to plant and `--clean` to restore. +# +# ## Value +# +# - **Concrete risk validation** — Evidence-based confirmation of whether an agent can be abused, including a per-attack-category breakdown of which sensitive file types were successfully exposed. +# - **Actionable remediation steps** — Custom recommendations generated from the results: path sanitization, file-system allowlists, intent-aware guardrails, least-privilege enforcement, and more. +# - **Repeatable governance** — A standardized red-team evaluation that can be run pre-deployment or continuously via CI/CD integration. +# +# ## How It Works +# +# 1. We load **attack objectives** from PyRIT's built-in `sensitive_data_access` seed dataset, covering direct, social engineering, obfuscated, and tool-chaining attack vectors +# 2. We configure a **canary-based scorer** that detects whether the agent's response contains ANY of the canary markers planted in sensitive files — each file category has a unique marker +# 3. We run the attack using `PromptSendingAttack` and print results using `ConsoleAttackResultPrinter` +# 4. We generate **actionable hardening recommendations** based on which vulnerability categories were exploited +# +# ## Prerequisites +# +# Before running this notebook, make sure you have the following set up: +# +# ### 1. A Running Agent with Tool Access +# You need an AI agent exposed over HTTP that has tool capabilities (e.g., file read, code execution, command execution). This can be built with any framework — **LangChain**, **Semantic Kernel**, **AutoGen**, **CrewAI**, or your own custom agent. +# +# The agent must: +# - Accept prompts via an HTTP endpoint (e.g., `POST /chat`) +# - Have access to tools that can interact with the file system or run commands +# - Be deployed in an environment where canary files have been planted (see step 2) +# +# > **Example:** This repo includes a ready-to-use LangChain sandbox agent under `docker/agent-sandbox/`. See the [Agent Security overview](./0_agent_security.md#agent-sandbox-setup) for setup instructions. +# +# ### 2. Canary Files Planted in the Agent's Environment +# The scorer works by detecting **canary markers** — unique strings planted inside sensitive files in the agent's environment. Each file category (shadow, passwd, SSH keys, etc.) has its own marker. +# +# You can plant canary files using either method: +# - **Docker** — Use [`Dockerfile.canary-template`](../../../../docker/agent-sandbox/Dockerfile.canary-template) to bake canaries into your container image +# - **No Docker** — Run [`plant_canaries.py`](../../../../docker/agent-sandbox/plant_canaries.py) to plant canary files at their real system paths (`python docker/agent-sandbox/plant_canaries.py`) +# +# The marker strings are defined in the notebook below as `CANARY_MARKERS`. The full canary content is defined in [`plant_canaries.py`](../../../../docker/agent-sandbox/plant_canaries.py). +# +# ### 3.
