macOS Entitlement Audit

This project is a security-oriented macOS entitlement auditing toolkit designed to extract, analyze, and identify potentially dangerous entitlements in macOS application binaries. It reflects a practical understanding of macOS code signing, binary analysis, and privilege boundaries within the Apple ecosystem.

• Automate extraction of application entitlements using codesign
• Identify insecure or debugging-related entitlements (get-task-allow, disable-library-validation, etc.)
• Showcase security tooling logic through lightweight scripting
• Document potential risks associated with misconfigured entitlements

This project is meant for demonstration and must be run in a macOS environment.

• macOS 12+ (tested on Sonoma in a VM)
• Command-line tools:
  • codesign
  • bash
  • grep

1. Input Preparation:

   • List target application paths in a targets.txt file.

2. Extraction (scripts/extract_entitlements.sh):

   • Uses codesign to extract entitlements and save them to data/ as .plist files.

3. Analysis (scripts/scan_suspicious.sh):

   • Searches for high-risk entitlements using grep pattern matching.

4. Documentation (docs/):

   • Contains explanations of entitlement types and associated risks.

• com.apple.security.get-task-allow
• com.apple.security.cs.disable-library-validation
• com.apple.security.cs.allow-dyld-environment-variables

These may allow debugging, dynamic code injection, or bypassing library validation.

• Hands-on familiarity with macOS application security
• Entitlement auditing and security configuration analysis
• Practical scripting for static security assessments

This repository is for educational and professional demonstration purposes only. Do not scan or extract entitlements from systems or binaries you do not own or have permission to analyze.

This project was developed as part of my personal cybersecurity lab work and is intended to demonstrate real-world security auditing skills. It is optimized for readability and structured for practical use in red team or audit settings.
