# 🛡️ Sentinel Sentinel is a basic SDK for implementing some security related features into your existing application,

What's Ready Now (As of 7/9/25)

• Intelligent Logging: Colored console output with automatic file audit trails
• VM Detection Module: Detect whether your software is being ran within a Virtual Machine or Sandboxed environment
• Persistence Module: Install and uninstall startup & service level persistence.
• Examples: Components described above all have full example usages completed.

Planned Arsenal

Sentinel is designed to become your complete security research platform:

• ✅ VM Detection - Unmask virtual environments
• 🔄️ Anti-Debug Evasion - Detect and counter debugging attempts from malicious actors
• Process Deep Dive - Comprehensive system process analysis and behavioral monitoring
• Network Intelligence - Advanced network beacon detection and communication analysis
• ✅ Persistence Hunting - Install and uninstall startup & service level persistence mechanisms
• Authentication - Hardware fingerprinting, license validation, and tamper protection
• Crypto Helper - Cryptographic utilities including SHA256 hashing, AES encryption, HMAC generation, and base64 encoding/decoding
• Filesystem Monitor - Realtime directory watching with callbacks for file creation, modification, and deletion events
• Memory Analyzer - Process memory dumping, pattern scanning, and executable memory detection for dynamic analysis
• API Monitor - Function hooking framework with callback system for monitoring API calls in target processes
• Network Monitor - Packet capture, process-specific traffic filtering, and active connection enumeration
