Top Risks

• NewTab override operator cluster: 11 sibling extensions under same fingerprint — industrial-scale wallpaper/newtab shell factory.
• Privacy policy URL 404/fetch-error: policy unverifiable; treated as absent (score +10).
• Uninstall and install URL hijack to gameograf.com UTM links — traffic monetization pattern.
• No CSP on MV3 + innerHTML DOM-XSS sinks in popup.js and calendar.js.
• operator_cluster sibling_count=11 with 39 extensions sharing same dev email — high blast-radius operator.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• operator_cluster api 11 compound siblings; 39 extensions share same dev email support@gameograf.com.
• privacy_policy_fetch_error api Privacy policy URL returned HTTPError — content unverifiable; treated as absent.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with DOM sinks.
• developer_name_missing store developer_name is empty string; reduces accountability signal.

Permissions Breakdown

• search medium Allows querying/intercepting search; paired with NewTab override amplifies monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab — high-reach surface for search hijack and ad monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; relatively contained.
