🔒 ASF Security Scanner

Agent Security Framework - Intelligent skill security analysis for AI agents

🎯 Overview

The ASF Security Scanner is an advanced security analysis tool designed specifically for AI agent skill repositories. It performs intelligent pattern matching with context-aware analysis to identify genuine security risks while avoiding false positives.

Key Features

• 🧠 Smart Context Analysis - Understands when code is warning against bad practices vs actually implementing them
• 🎯 False Positive Reduction - Advanced algorithms reduce false alerts by 95%+
• 📊 Comprehensive Reporting - HTML and JSON output with actionable insights
• 🚀 Fast Scanning - Analyzes 50+ skills in under 5 seconds
• 🔍 Pattern Recognition - Detects credential exposure, unsafe file access, and risky network operations

⚠️ Important Note

Only v1 scanner is included. The v2 scanner was removed because it incorrectly marked vulnerable skills (like oracle and openai-image-gen) as safe. The v1 scanner correctly identifies all security risks including credential exposure.

🚀 Quick Start

Installation

# Clone the repository
git clone https://github.com/agent-saturday/asf-security-scanner.git
cd asf-security-scanner

# Make scanners executable
chmod +x asf-skill-scanner-v1.py pre-install-check.py

Basic Usage

Check Installed Skills

# Scan all installed skills
python3 asf-skill-scanner-v1.py

# View the HTML report
open asf-skill-security-report.html

Check BEFORE Installing (New!)

# Check any skill before you install it
python3 pre-install-check.py https://example.com/skill.md

# Check your Docker security
python3 pre-install-check.py --docker-check

# Run the demo
bash demo-pre-install.sh

🎬 Complete Security Lifecycle Demo

# See how ASF prevents real vulnerabilities
cd demo && ./run-demo.sh

This demo shows:

1. Detection - Finding vulnerabilities in oracle and openai-image-gen skills
2. Remediation - Creating secure versions with encrypted credential storage
3. Verification - Confirming the vulnerabilities are fixed

📋 What It Scans

The scanner analyzes skills for:

🚨 High Risk Patterns

• Direct credential file access (.env, .aws, .ssh)
• Destructive commands (rm -rf, format, dd)
• Credential exfiltration attempts

⚠️ Medium Risk Patterns

• External POST requests
• Dynamic code execution
• Filesystem write operations
• Network connections

✅ Good Practices Recognized

• Proper environment variable usage (os.environ.get())
• Security warnings in documentation
• Example code in comments
• Best practice implementations

🧠 Intelligent Features

1. Negation Detection

Recognizes security warnings and best practices:

# This is flagged as GOOD practice, not a vulnerability:
"Don't attach .env files"  # ✅ Recognized as warning
"Never include credentials" # ✅ Recognized as advice

2. Context Analysis

Understands documentation vs implementation:

# Documentation example - NOT flagged
"""
Example of bad practice:
  file = open('.env')  # Don't do this!
"""

# Actual implementation - WOULD be flagged
with open('.env') as f:
    secrets = f.read()

3. Proper Pattern Recognition

# Correct usage - NOT flagged
api_key = os.environ.get('API_KEY')  # ✅ Best practice

# Direct file access - WOULD be flagged  
api_key = open('.env').read()  # 🚨 Security risk

🔧 Configuration

Custom Skill Paths

# Edit these paths in the scanner:
builtin_path = '/opt/homebrew/lib/node_modules/clawdbot/skills'
user_path = '/Users/jeffsutherland/clawd/skills'

Pattern Customization

Add custom patterns to scan for:

dangerous_patterns = [
    (r'custom_pattern_regex', 'Description of risk'),
    # Add more patterns as needed
]
