Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Mitsubishi Lancer Evolution Anime Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; ADMITS data collection and 3rd-party sharing (+10.0 privacy).
• Uninstall URL hijack AND install URL hijack to gameograf.com — monetization/tracking shell pattern (+3.0+2.0 webstore).
• NewTab override replaces every new-tab page; search permission adds search-provider influence (+2.0 webstore).
• No CSP (csp_present=false) with innerHTML DOM-XSS sink in calendar.js — code quality risk.

Evidence

• uninstall_url_hijack + install_url_hijack manifest Both onInstalled and onUninstall redirect to gameograf.com UTM-tracked URLs — monetization shell fingerprint.
• privacy_policy_generic store Policy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — captures every new tab for all users.
• dom_sink_innerhtml_userctrl crx js/calendar.js uses innerHTML from variable with no CSP — DOM-XSS risk.
• no_csp manifest content_security_policy is null on MV3 extension with innerHTML sink — amplifies code quality risk.
• verified_publisher store Extension has verified_publisher=true; provides partial reputation discount.
• developer_name_blank store developer_name is empty string — no displayed developer identity.
• low_installs_newtab store Only 233 installs; newtab override with search permission is high-impact relative to user base.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Mitsubishi Lancer Evolution Anime Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.72 -> 7.22 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating browser search settings; supports newtab search override.
• alarms low Scheduling only; minimal risk on its own.
• storage low Local data persistence; low risk alone.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer's own API domain; acceptable for a newtab extension.
• chrome_url_overrides.newtab medium Replaces new tab page; monetization vector, captures all new-tab navigations.
