PUA - WebBrowserPassView Execution

Sigma Rules

View Source
Summary
The rule detects the execution of 'WebBrowserPassView.exe', a utility used for recovering passwords stored in various web browsers such as Internet Explorer, Mozilla Firefox, Google Chrome, Safari, and Opera. This tool can be used legitimately by users to recover forgotten passwords but may also be misused by attackers to extract sensitive information without the user's consent. The rule is intended to monitor for this executable's launch on Windows systems, indicating potential unauthorized access or credential theft. The detection is facilitated by monitoring process creation events and filtering for specific characteristics of the executable associated with the password viewer. The inclusion of known false positives, namely legitimate use cases, is acknowledged, thereby denoting the medium risk level associated with detection incidents.
