Worst Case
Complete system compromise where a malicious app gains full system access, installs persistent malware, accesses sensitive user data, and controls other applications.
Likely Case
Malicious app escapes sandbox to access files, system resources, or other applications' data that should be restricted, potentially stealing credentials or sensitive information.
If Mitigated
Limited impact due to other security controls like System Integrity Protection (SIP), Gatekeeper, and user permissions restricting what escaped apps can access.
