Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Demon in Crimson Shadows Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall AND install URL hijacked to gameograf.com with UTM tracking — confirmed monetization shell pattern.
• Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and third-party sharing (+10 privacy).
• New-tab override with 'search' permission is classic search-monetization vector.
• Free-webmail developer (gmail) with no verified business website or publisher badge.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=ovkas (confirmed 3rd-party UTM redirect).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=ovkas — monetization shell fingerprint.
• newtab_override manifest chrome_url_overrides.newtab = index.html; combined with 'search' permission = search-monetization pattern.
• generic_privacy_policy store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension; data_collection+third_party_sharing=true.
• free_webmail_developer store Developer email halilseker3455@gmail.com; no verified publisher badge; no business domain.
• external_hosts_excessive crx JS contacts 6 external hosts: gameograf.com, google.com, instagram.com, netflix.com, youtube.com, x.com — far beyond wallpaper function.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
• low_install_monetization_shape store Only 111 installs; uninstall+install hijacks to gameograf.com indicate traffic-monetization infrastructure already in place.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Demon in Crimson Shadows Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.41 -> 7.91 (+2.5 cap 2.5).

Permissions Breakdown
