Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Rainbow Unicorn Magic Night Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com — classic monetization shell pattern.
• NewTab override with search permission: intercepts every new tab for ad/search monetization.
• Privacy policy is Google's generic policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• Free-webmail dev (gmail) with no verified publisher, no business domain — low accountability.

Evidence

• uninstall_url_hijack manifest onUninstall redirects to gameograf.com with UTM params (ovkas campaign) — monetization shell indicator.
• install_url_hijack manifest onInstalled opens gameograf.com with same UTM params — double hijack confirms monetization intent.
• newtab_override manifest chrome_url_overrides.newtab = index.html; wallpaper theme as cover for NewTab ad monetization.
• privacy_policy_generic store Policy URL is Google's own account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_dev store Developer email halilseker3455@gmail.com — numbered alias pattern, no verified business domain.
• js_external_hosts crx Extension JS references gameograf.com plus instagram, netflix, youtube, x.com — broad social/media reach.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit scope hardening.
• search_permission_newtab_combo manifest search permission + newtab override is the canonical search-monetization pair for wallpaper shells.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Rainbow Unicorn Magic Night Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.11 -> 8.61 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; combined with newtab override signals monetization intent.
• chrome_url_overrides.newtab high Replaces new tab page; core mechanism for ad-monetization NewTab shells.
