Top Risks

• Uninstall URL hijack redirects to gameograf.com ad-tracker with UTM campaign params — clear monetization shell.
• Install URL hijack also fires gameograf.com on every install; double monetization trigger.
• NewTab override replaces all new tabs; paired with search permission enables ad-monetization pipeline.
• Privacy policy is Google's own generic policy — not scoped to this extension, admits data collection and 3rd-party sharing.
• Free-webmail dev (gmail) with no business domain; throwaway operator identity, no accountability.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → gameograf.com with UTM ovkas params; classic monetization shell.
• install_url_hijack manifest onInstalled opens gameograf.com with same UTM params; double redirect monetization.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab controlled by extension.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email halilseker3455@gmail.com; no business domain, no verified publisher.
• js_external_hosts crx Extension references gameograf.com, instagram.com, netflix.com, youtube.com, x.com — 5 unrelated domains.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• search_permission_newtab_combo manifest search permission + newtab override = typical ad-monetization aggregator pattern.

Permissions Breakdown

• search medium Allows search provider interaction; medium risk on its own but combined with newtab override raises concern.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page; high-reach monetization surface.
