Top Risks

• NewTab override with install/uninstall URL hijack to gameograf.com — monetization shell pattern.
• Privacy policy is Google's generic policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Uninstall URL hijack fires to gameograf.com with UTM tracking on every removal.
• Install URL hijack opens gameograf.com on every install — onboarding monetization.
• Two innerHTML DOM-XSS sinks present with no CSP; MV3 default CSP mitigates but sinks remain risky.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab with extension UI.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• generic_privacy_policy api Privacy URL is Google's own policy (myaccount.google.com/privacypolicy); scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx Two innerHTML assignments from variables in popup.js and calendar.js with no CSP.
• search_permission manifest search permission declared alongside newtab override — search monetization pattern.
• developer_name_missing store developer_name is empty string; no 'Offered by' attribution visible.
• verified_publisher store verified_publisher=true; domain resolves; mitigates reputation somewhat but doesn't cover monetization patterns.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for NewTab/search monetization.
• 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 — primary monetization surface for this category.
