Non-browser process accessing Chrome passkey_enclave_state file
Detects unauthorized access, creation, modification, or deletion of the 'passkey_enclave_state' file within the Google Chrome user data directory by processes other than 'chrome.exe'. This file contains sensitive cryptographic material related to Chrome's synced passkey cloud authenticator, and non-browser process interaction with it is indicative of potential credential theft or passkey exfiltration (e.g., 'Golden/Silver Pass-ta-key' attacks).
