This analytic is designed to identify non-chrome processes accessing the Chrome user data file called "login data." This SQLite database file contains important information related to the browser's operations on the computer. Threat actors, adversaries, and malware authors have been known to exploit this file in attempts to extract and decrypt passwords saved in the Chrome browser. Detecting access to the "login data" file by non-chrome processes serves as a valuable pivot for analyzing suspicious processes beyond the commonly observed chrome.exe and explorer.exe executables. By monitoring for this anomaly, we can enhance our ability to detect potential threats and protect sensitive information stored within the browser.

The SPL above uses the following Macros:

:information_source: windows_credentials_from_password_stores_chrome_login_data_access_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

How To Implement

To successfully implement this search, you must ingest Windows Security Event logs and track event code 4663. For 4663, enable "Audit Object Access" in Group Policy. Then check the two boxes listed for both "Success" and "Failure."

Known False Positives

Uninstall application may access this registry to remove the entry of the target application. filter is needed.
