Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Samurai Anime Girl Neon Cyberpunk Car Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own generic policy — not scoped to this extension, admits data collection and third-party sharing (Privacy: 10.0).
• NewTab override replaces every new tab; uninstall and install URL hijacks redirect users to gameograf.com for traffic monetization.
• Two innerHTML-from-variable sinks (popup.js, calendar.js) with no CSP — DOM-XSS risk elevated.
• No developer name listed; verified publisher but policy is a generic Google URL not representing this extension's data practices.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — every new tab replaced; medium-reach monetization surface.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM tracking params — webstore +3.0.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params — webstore +2.0.
• generic_privacy_policy api Privacy policy URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• dom_xss_no_csp crx Two innerHTML sinks in popup.js and calendar.js; csp_present=false amplifies DOM-XSS risk to +2.0 each.
• no_developer_name store developer_name is empty string — reputation +1.0 (no 'Offered by' name).
• verified_publisher store Verified publisher badge present; discount applied but capped by generic policy (invariant 0c not triggered — domain resolves, <18mo, no CVEs).
• search_permission_newtab manifest search permission combined with newtab override is classic NewTab monetization cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Samurai Anime Girl Neon Cyberpunk Car Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.56 -> 7.06 (+2.5 cap 2.5).
