Code Review
This pull request introduces the UnbackedMutexCreation signature to detect mutex creation or queries originating from dynamically allocated (unbacked) memory, which is a common technique used by fileless payloads. The review feedback suggests expanding the monitored API list to include OpenMutexA and OpenMutexW for better coverage and adding a validation check to ensure that only non-zero memory base addresses are tracked to prevent invalid range entries.
