Top Risks

• Google's privacy policy used as extension policy — does not scope data collection to this extension at all.
• Uninstall URL hijack redirects to gameograf.com UTM tracking on removal.
• Install URL hijack opens gameograf.com UTM page on installation — monetization shell pattern.
• NewTab override + search permission = high-value ad-monetization surface with 277 installs.
• No CSP + two innerHTML-from-variable sinks increase DOM-XSS risk.

Evidence

• privacy_policy_generic store Policy URL is Google's own account privacy policy; scope_extension=false, data_collection=true, third_party_sharing=true — worst-case classification.
• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=pusheen&utm_medium=install
• newtab_override_monetization manifest chrome_url_overrides.newtab = newtab.html with search permission — classic monetization shape.
• no_csp manifest content_security_policy is null; MV3 strict default applies but no explicit CSP declared.
• dom_xss_sinks crx Two innerHTML-from-variable sinks in popup.js and calendar.js without CSP guard.
• developer_name_missing store developer_name is empty string; reduces accountability.
• verified_publisher store verified_publisher=true mitigates reputation slightly; domain resolves and is not throwaway.

Permissions Breakdown

• search medium Allows overriding search provider; paired with newtab override amplifies search-monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; core monetization surface for this category.
