Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Itachi Uchiha Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns HTTP error — effectively no accessible policy; scored as fetched==false (+10.0).
• NewTab override with uninstall/install URL hijack to gameograf.com — classic traffic-monetization shell pattern.
• Verified publisher discount capped at -1.0 due to months_since_update=15 (>12, <18) triggering staleness and inaccessible privacy policy.
• innerHTML DOM-XSS sink in popup.js with no CSP present — elevated code risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — full new-tab hijack.
• install_uninstall_url_hijack manifest Both install and uninstall redirect to gameograf.com UTM URLs — monetization pattern.
• privacy_policy_fetch_failed api privacy_policy_classification.fetched=false, reason=fetch_error:HTTPError. Policy inaccessible.
• privacy_policy_domain_mismatch store Policy URL on haberikra.com, dev domain gameograf.com — unrelated domain.
• csp_absent manifest content_security_policy is null; csp_present=false on MV3 extension.
• dom_xss_sink crx dom_sink_innerhtml_userctrl in js/popup.js; no CSP to mitigate XSS.
• verified_publisher_stale store verified_publisher=true but months_since_update=15; cap discount at -1.0 per invariant 0c.
• developer_name_missing store developer_name is empty string — no identifiable publisher name in listing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Itachi Uchiha Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.37 -> 7.87 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating browser search; medium risk in newtab context.
• chrome_url_overrides.newtab high Replaces new-tab page — primary monetization vector for traffic/search hijack.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain; low surface by itself.
