Running Benchmarks

Basic Commands

# List all available benchmarks
pentestgpt-benchmark list

# Filter by difficulty level (1, 2, or 3)
pentestgpt-benchmark list --levels 1

# Filter by vulnerability tag
pentestgpt-benchmark list --tags sqli

# Show all tags for each benchmark
pentestgpt-benchmark list --show-tags

# Start a specific benchmark
pentestgpt-benchmark start XBEN-001-24

# Check running benchmarks
pentestgpt-benchmark status

# Stop a benchmark
pentestgpt-benchmark stop XBEN-001-24

Manual Testing Workflow

1. Start a benchmark container:

pentestgpt-benchmark start XBEN-037-24
# Container will be accessible at http://0.0.0.0:<port>

2. Connect to PentestGPT container:

make connect

3. Run PentestGPT against the benchmark:

pentestgpt --target http://host.docker.internal:<port>

4. Clean up when done:

pentestgpt-benchmark stop XBEN-037-24

Automated Testing

For comprehensive automated testing, use the standalone benchmark runner.

Setup

# Navigate to the runner directory
cd benchmark/standalone-xbow-benchmark-runner

# Ensure Docker is running
docker ps

Usage

# Preview what will be executed (recommended first step)
python3 run_benchmarks.py --dry-run --range 1-5 --pattern-flag

# Run a single benchmark with strict flag validation
python3 run_benchmarks.py --range 1-1 --pattern-flag

# Run multiple benchmarks
python3 run_benchmarks.py --range 1-10 --pattern-flag

# Run all 104 benchmarks
python3 run_benchmarks.py --all --pattern-flag

# Run with extended timeout (default is 15 minutes)
python3 run_benchmarks.py --range 1-10 --pattern-flag --timeout 1800

# Resume interrupted run
python3 run_benchmarks.py --resume --pattern-flag

# See all options
python3 run_benchmarks.py --help

Features

• Automated execution: Headless benchmark testing via Docker
• Comprehensive logging: Per-benchmark logs saved to logs/ directory
• Flag verification: Automatic detection and validation using regex patterns
• Resumption support: Resume interrupted runs without re-running completed benchmarks
• Cost tracking: API cost and execution time analysis
• Summary reports: Detailed results with success rates, costs, and timing statistics

See standalone-xbow-benchmark-runner/README.md for detailed usage instructions.

Benchmark Structure

All benchmark suites follow a consistent structure:

benchmark/
├── <benchmark-suite-name>/
│   ├── <BENCHMARK-ID>/
│   │   ├── benchmark.json        # Metadata (name, tags, level, port)
│   │   ├── docker-compose.yml    # Container configuration
│   │   ├── challenge/            # Vulnerable application code
│   │   └── solution/             # Reference solution (optional)
│   └── ...
└── standalone-<suite>-runner/    # Automated runner (optional)

├── XBEN-001-24/
│   ├── benchmark.json
│   ├── docker-compose.yml
│   ├── challenge/
│   └── solution/
└── ...

Benchmark Metadata

Each benchmark.json contains:

{
  "name": "XBEN-001-24",
  "description": "SQL Injection vulnerability",
  "level": 1,
  "tags": ["sqli", "web"],
  "port": 8001,
  "flag_format": "HTB{...}"
}

Difficulty Levels

• Level 1 (Easy): Single-step vulnerabilities, basic exploitation
• Level 2 (Medium): Multi-step attacks, moderate complexity
• Level 3 (Hard): Advanced exploitation, chained vulnerabilities

Adding New Benchmark Suites

PentestGPT's benchmark system is designed to support multiple benchmark suites. To add a new benchmark suite:

Requirements

1. Directory structure: Create a new directory under benchmark/ with a descriptive name
2. Benchmark metadata: Each challenge must have a benchmark.json file with:
   • name: Unique benchmark identifier
   • description: Brief description of the vulnerability
   • level: Difficulty level (1-3)
   • tags: List of vulnerability categories
   • port: Port the container exposes
   • flag_format: Expected flag format (e.g., FLAG{...})
3. Docker containerization: Each challenge must have a docker-compose.yml
4. Registry integration: Update pentestgpt/benchmark/registry.py to discover the new suite

Contributing Individual Benchmarks

To add new benchmarks to an existing suite (e.g., XBOW):

1. Create a new directory following the suite's naming convention
2. Add benchmark.json with appropriate metadata
3. Create docker-compose.yml with the vulnerable application
4. Include challenge files in challenge/ directory
5. Optionally add reference solution in solution/
6. Test the benchmark manually before submitting
