Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sanrio Hello Kitty Little Red Riding Hood Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack to gameograf.com — classic ad-monetization shell pattern.
• Uninstall and install URL hijacks both redirect to gameograf.com with UTM tracking.
• DOM-XSS sinks (innerHTML from variable) in popup.js and calendar.js with no CSP present.
• No developer name listed; theme/wallpaper shell pattern with search permission and newtab override.

Evidence

• uninstall_url_hijack manifest setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install — 3rd-party tracking.
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install — ad-monetization signal.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — captures all new-tab navigations for 111 users.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP mitigates DOM-XSS risk.
• no_csp manifest content_security_policy is null on MV3 extension; no extra hardening beyond browser default.
• verified_publisher store gameograf.com verified; domain resolves, not throwaway, reduces reputation risk modestly.
• privacy_policy_third_party_sharing api Privacy policy fetched; scope_extension=true, data_collection=true, third_party_sharing=true, retention=true.
• search_permission_newtab_combo manifest search permission + newtab override is a known revenue-capture pattern for wallpaper/theme shells.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sanrio Hello Kitty Little Red Riding Hood Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.54 -> 5.04 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; medium risk on its own but combined with newtab override raises concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page — high reach, ad-monetization risk, captures all new-tab navigations.
