Deletion of Chrome Passkey Enclave State File Forcing Passkey Re-onboarding
Detects deletion of the Chrome passkey_enclave_state file by a process other than chrome.exe or the Chrome updater. Legitimate deletions of this file occur during Chrome uninstall/reinstall, user-initiated 'Clear Browsing Data' or profile reset actions, Chrome profile deletion via chrome://settings, and Chrome auto-update operations - all of which are performed by chrome.exe or the Google Update process/updater tree and are excluded here. Deletions by any other process are flagged as suspicious. Analysts should further prioritize alerts where the deletion is immediately followed by unexpected passkey re-registration/re-onboarding activity, correlated separately via re-onboarding indicators.
