2. Monitor process crashes and application errors through SIEM
3. Restrict user permissions to prevent license key field access
4. Isolate affected systems from critical network segments
Detection Rules:
1. Monitor for Duplicate Cleaner Pro crashes with event ID 1000 (Application Error)
2. Alert on license key field input exceeding 256 bytes
3. Track failed application initialization attempts
4. Monitor for stack overflow exceptions in application logs
