Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Spider Man Minimalist HD Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijack to gameograf.com — confirmed monetization shell pattern.
• New-tab override with search permission: captures 100% of new-tab traffic for potential ad monetization.
• Privacy policy is Google's own generic policy — not scoped to this extension, admits data collection and third-party sharing (+10).
• Free-webmail developer (gmail), no verified publisher, no business domain — low accountability.

Evidence

• uninstall_url_hijack crx setUninstallURL targets gameograf.com with utm tracking — classic monetization shell fingerprint.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab served by this extension.
• privacy_policy_generic store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, scope_extension=false, admits 3rd-party sharing.
• free_webmail_developer store Developer email sinanalkan2737@gmail.com, no business domain, no verified publisher badge.
• js_external_hosts crx gameograf.com + 5 major platforms in JS hosts; gameograf.com is the monetization operator domain.
• search_permission_with_newtab manifest search + newtab override = search monetization combo; search_engine_count=1 (google only).
• no_csp crx csp_present=false on MV3 extension; v2 calibration +2.0 Network for MV2 does not apply, but no CSP noted.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Spider Man Minimalist HD Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.27 -> 8.77 (+2.5 cap 2.5).
