What is Strix?

Strix is a revolutionary open-source AI security testing platform that fundamentally changes how we approach cybersecurity assessments. Unlike traditional static analysis tools that generate numerous false positives, Strix operates as autonomous AI agents that think and act like real hackers.

🦉 Key Features

🛠️ Complete Hacker Toolkit

  • HTTP Proxy: Full request/response manipulation and analysis
  • Browser Automation: Multi-tab browser testing for XSS, CSRF, and authentication flows
  • Terminal Environments: Interactive shells for command execution and testing
  • Python Runtime: Custom exploit development and validation
  • Reconnaissance Tools: Automated OSINT and attack surface mapping

🎯 Comprehensive Vulnerability Detection

  • Access Control (IDOR, privilege escalation, auth bypass)
  • Injection Attacks (SQL, NoSQL, command injection)
  • Server-Side Vulnerabilities (SSRF, XXE, deserialization)
  • Client-Side Issues (XSS, prototype pollution, DOM vulnerabilities)
  • Business Logic Flaws (race conditions, workflow manipulation)
  • Authentication Issues (JWT vulnerabilities, session management)

🕸️ Distributed Agent Architecture

  • Specialized agents for different attack types
  • Scalable parallel execution
  • Dynamic agent collaboration and knowledge sharing

Why Choose Strix Over Traditional Tools?

Traditional Security Testing Problems

  1. Static Analysis Tools: High false positive rates, miss runtime vulnerabilities
  2. Manual Penetration Testing: Expensive, time-consuming, limited coverage
  3. Automated Scanners: Shallow testing, no actual exploitation validation

Strix Advantages

✅ Real Validation: Actual exploitation attempts, not just potential issues
✅ Dynamic Testing: Runtime analysis with full application context
✅ AI-Powered: Intelligent decision-making and adaptive testing strategies
✅ Developer-Friendly: Seamless CI/CD integration
✅ Cost-Effective: Reduce dependency on expensive manual testing

Installation and Setup

Prerequisites

Before installing Strix, ensure you have:

  • Python 3.8+: Required for the core agent runtime
  • Docker: Essential for container isolation and safe testing
  • pipx: Python application installer (recommended)
  • AI Provider API Key: OpenAI, Anthropic, or other supported LLM providers

Step 1: Install pipx (if not already installed)

# macOS with Homebrew
brew install pipx
pipx ensurepath

# Ubuntu/Debian
sudo apt update
sudo apt install pipx
pipx ensurepath

# Alternative: pip installation
python -m pip install pipx
python -m pipx ensurepath

Step 2: Install Strix

# Install Strix agent
pipx install strix-agent

# Verify installation
strix --help

Step 3: Configure AI Provider

Strix requires an LLM provider for intelligent decision-making:

# OpenAI (Recommended)
export STRIX_LLM="openai/gpt-4"
export LLM_API_KEY="your-openai-api-key"

# Alternative providers
export STRIX_LLM="anthropic/claude-3-sonnet"
export LLM_API_KEY="your-anthropic-api-key"

# Optional: Enhanced research capabilities
export PERPLEXITY_API_KEY="your-perplexity-api-key"

Step 4: Verify Docker Setup

# Check Docker status
docker info

# If Docker is not running, start Docker Desktop
# Download from: https://www.docker.com/products/docker-desktop/

Complete Setup Script

For automated installation on macOS, use our comprehensive setup script:

#!/bin/bash
# Save as setup_strix.sh and run: chmod +x setup_strix.sh && ./setup_strix.sh

set -e

echo "🦉 Strix Setup for macOS"
echo "========================"

# Install pipx if not present
if ! command -v pipx &> /dev/null; then
    echo "Installing pipx..."
    brew install pipx
    pipx ensurepath
fi

# Verify Docker
if ! docker info &> /dev/null; then
    echo "⚠️  Docker is not running. Please start Docker Desktop."
    exit 1
fi

# Install Strix
echo "Installing Strix..."
pipx install strix-agent

# Verify installation
if command -v strix &> /dev/null; then
    echo "✅ Strix installed successfully!"
    strix --help | head -5
else
    echo "❌ Installation failed"
    exit 1
fi

echo "🎉 Setup complete! Don't forget to set your API keys."

Security Best Practices

Ethical Usage Guidelines

⚠️ CRITICAL: Only test systems you own or have explicit permission to test.

  1. Authorization: Always obtain written permission before testing
  2. Scope Limitation: Define clear testing boundaries
  3. Data Protection: Avoid accessing sensitive production data
  4. Responsible Disclosure: Follow proper vulnerability reporting procedures

Safe Testing Environment

# Create isolated testing environment
docker network create strix-test

# Run applications in contained environment
docker run --network strix-test --name target-app your-app:latest

# Run Strix against contained target
strix --target http://target-app:8080

Troubleshooting Common Issues

Installation Problems

Issue: pipx installation fails

# Solution: Update Python and pip
python -m pip install --upgrade pip
pipx upgrade strix-agent

Issue: Docker connectivity errors

# Solution: Verify Docker daemon
docker version
docker ps

# Restart Docker if needed
sudo systemctl restart docker  # Linux
# Restart Docker Desktop on macOS/Windows

Runtime Issues

Issue: LLM API rate limiting

# Solution: Implement request throttling
export STRIX_LLM_RATE_LIMIT=10  # requests per minute

Issue: Incomplete vulnerability detection

# Solution: Increase scan depth and timeout
strix --target ./app \
      --instruction "Perform deep analysis with extended timeout" \
      --timeout 7200

Advanced Features

Custom Agent Development

Strix supports custom agent development for specialized testing:

# custom_agent.py
from strix.agents import BaseAgent

class CustomSQLiAgent(BaseAgent):
    def __init__(self):
        super().__init__("custom-sqli-agent")
    
    async def execute(self, target):
        # Custom SQL injection testing logic
        payloads = ["' OR 1=1--", "'; DROP TABLE users;--"]
        for payload in payloads:
            result = await self.test_payload(target, payload)
            if result.vulnerable:
                return self.create_finding(
                    title="SQL Injection Detected",
                    severity="critical",
                    payload=payload,
                    evidence=result.response
                )
