Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Hello Kitty Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijacks both redirect to gameograf.com — confirmed monetization shell pattern.
• Privacy policy is Google's own generic policy (scope_extension=false, admits data collection and 3rd-party sharing) — does not describe this extension at all.
• NewTab override paired with search permission creates ad-monetization surface on every new tab open.
• No CSP declared (MV3 default applies but no explicit policy) and extension contacts 6 external hosts including major platforms.

Evidence

• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=ovkas — confirmed monetization redirect on install.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=ovkas — same ad-tech domain on uninstall.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab with extension page.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true — triggers +10 privacy.
• external_hosts crx JS contacts gameograf.com, google.com, instagram.com, netflix.com, youtube.com, x.com — 6 distinct domains.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit policy hardening.
• game_portal_shell store Install/uninstall both route to gameograf.com with UTM params — classic game-portal shell monetization pattern.
• unverified_developer store No verified publisher badge, no featured badge; developer Ovkas/ovkas.com unverified; 312 installs, 0 ratings.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Hello Kitty Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.22 -> 7.72 (+2.5 cap 2.5).
