Chrome Extension Metadata Target and Module

[Reuerb]

Adding Chrome extension metadata parser target and module. Analyzes manifest and messages JSON files.

Description

The ChromeExtension_Metadata.tkape file pulls the manifest/messages.json files from each extension on the host.
The PowerShell_ChromeExtension_Metadata.mkape file leverages a simple PowerShell script to go through each of the JSON files to pull out:

• Chrome extension friendly name
• Description
• Extension ID
• Version
• Permissions
• Host permissions

Finally, the results are put into a CSV for review. While some responders have enterprise-grade tools to assist in the permission review of extensions, this will help those less fortunate to identify malicious/unwanted extensions, and then pivot/hunt. As we know, browser extensions continue to be an issue.
