About:
Do Not Disturb (DND) is an open-source utility that monitors macOS for signs of physical tampering, also known as 'evil maid' attacks. It detects unauthorized changes to system startup processes, security settings, and kernel extensions. The tool provides real-time alerts to help users identify when their machine may have been compromised by physical access.
Key Features:
  • Real-time monitoring of system integrity and security settings
  • Detects unauthorized kernel extensions and startup item modifications
  • Provides instant notifications of suspicious activity
  • Lightweight, open-source implementation
  • Specifically designed to catch physical access attacks
Use Cases:
  • Protecting laptops from physical tampering when left unattended
  • Detecting evil maid attacks on sensitive workstations
  • Monitoring system integrity for security-conscious users
Alternatives:
  • KnockKnock – KnockKnock scans for persistent malware, while DND focuses on real-time physical attack detection
  • macOS File Integrity – Built-in SIP provides system protection but lacks specialized evil maid attack detection
