Top Risks

• Uninstall AND install URL both hijack to gameograf.com with UTM tracking — clear monetization shell pattern.
• Privacy policy is Google's own account policy, not scoped to this extension; policy admits data collection and 3rd-party sharing (+10 privacy pillar).
• NewTab override with gmail-only developer, no verified publisher, no business website — high-reputation risk floor.
• Free-webmail developer (yakupsaylan357@gmail.com) with no verified business; reputation floor applies.
• JS contacts 6 external hosts (gameograf.com, google, instagram, netflix, youtube, x.com) with no CSP on MV3.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with UTM params; 3rd-party redirect on uninstall.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params; monetization on install confirmed.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new-tab with extension page.
• generic_privacy_policy store Policy URL is Google Account policy, scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email yakupsaylan357@gmail.com; no business domain, no verified publisher badge.
• js_external_hosts crx 6 external hosts contacted: gameograf.com, google, instagram, netflix, youtube, x.com.
• no_csp manifest content_security_policy is null on MV3; no script-src restrictions declared.
• search_permission_newtab manifest search permission combined with newtab override matches monetization shell fingerprint.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk on its own but paired with newtab override.
• chrome_url_overrides.newtab medium Replaces new-tab page; classic monetization vector, scored per rubric 2(a).
