Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Red Eyes Anime Girl 4K Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — high daily-reach monetization surface.
• Uninstall URL hijack and install URL hijack both redirect to gameograf.com with UTM tracking.
• No CSP declared (MV3 default applies) combined with innerHTML DOM-XSS sinks in popup.js and calendar.js.
• No developer name listed in store; identity accountability gap.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party redirect).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install (3rd-party redirect).
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; csp_present == false. DOM sinks unmitigated.
• missing_developer_name store developer_name is empty string; no 'Offered by' identity in store listing.
• verified_publisher store verified_publisher == true; gameograf.com resolves; not throwaway. Partial reputation discount applied.
• privacy_policy_scope api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true. Adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Red Eyes Anime Girl 4K Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.68 -> 5.18 (+2.5 cap 2.5).

• chrome_url_overrides.newtab medium Replaces new-tab page; core monetization surface for this category.
