Name:Windows Credentials from Password Stores Chrome Login Data Access id:0d32ba37-80fc-4429-809c-0ba15801aeaf version:24 date:None author:Teoderick Contreras, Splunk status:production type:Anomaly Description:The following analytic identifies non-Chrome processes accessing the Chrome user data file "login data."
This file is an SQLite database containing sensitive information, including saved passwords.
The detection leverages Windows Security Event logs, specifically event code 4663, to monitor access attempts.
This activity is significant as it may indicate attempts by threat actors to extract and decrypt stored passwords, posing a risk to user credentials.
If confirmed malicious, attackers could gain unauthorized access to sensitive accounts and escalate their privileges within the environment. Data_source:
-Windows Event Log Security 4663

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:The chrome uninstaller will access these set of files and folders. Filter as needed.
