What it detects

This rule detects a Google Workspace OAuth authorize event granting the Chrome Web Store management scope to a third-party application such as the Privacy Policy Extension app seen in this supply chain campaign. Attackers trick users into authorizing apps that can publish or modify Chrome extensions, enabling downstream compromise of every user who installs the affected extension.
