🚫 Known Security Considerations

Inherent Risks

MelonLoader operates by injecting code into Unity applications. This inherently:

  • Requires elevated privileges on some systems
  • Can be flagged by antivirus software
  • Allows mods to access game memory
  • May bypass some game security measures

Mitigation Strategies

  • πŸ” Sandboxing: Mods run in controlled environment
  • πŸ›‘οΈ API Restrictions: Limited access to system functions
  • πŸ“ Logging: All mod actions are logged
  • ⚑ Quick Updates: Fast response to security issues
