Top Risks

  • Uninstall and install URL both hijacked to gameograf.com — classic traffic-monetization shell pattern.
  • New-tab override turns every new tab into a controlled page for affiliate/ad delivery.
  • Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and third-party sharing.
  • Free-webmail dev (gmail) with no verifiable business website; developer_domain resolves to gmail.com.
  • JS external hosts include gameograf.com alongside major platforms (YouTube, Netflix, Instagram) indicating tracking/redirect scaffolding.

Evidence

  • install_url_hijack crx onInstalled opens gameograf.com with UTM params tagged 'ovkas' — monetization shell signal.
  • uninstall_url_hijack crx setUninstallURL points to gameograf.com with identical UTM params — confirms traffic harvesting.
  • 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_developer store Developer email halilseker3455@gmail.com; no verified business domain; no publisher badge.
  • js_external_hosts crx Extension contacts gameograf.com plus YouTube, Netflix, Instagram, x.com — broad external surface.
  • no_csp manifest content_security_policy is null; MV3 strict default applies but no explicit policy declared.
  • search_permission_plus_newtab manifest 'search' permission combined with newtab override enables search-provider monetization.

Permissions Breakdown

  • search medium Allows querying browser search API; combined with newtab override elevates monetization risk.
  • chrome_url_overrides.newtab high Replaces every new tab — primary monetization/tracking surface for wallpaper shells.
