Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Girl in the Rain Cafe Window Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack to gameograf.com — classic traffic-monetization shell pattern.
• No developer name listed; verified publisher but no 'Offered by' display name reduces accountability.
• Two DOM-XSS innerHTML sinks with no CSP — no content_security_policy defined (MV3 default applied but no explicit hardening).
• Search permission paired with newtab override enables covert search-provider manipulation.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• dom_xss_sink 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; no explicit script-src hardening on MV3 extension.
• verified_publisher store Verified publisher badge present; domain gameograf.com resolves and is not throwaway.
• privacy_policy_scope api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; no 'Offered by' display name in listing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Anime Girl in the Rain Cafe Window Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.07 -> 6.57 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search; paired with newtab override, enables search hijacking.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab high Replaces every new tab — prime real estate for ad monetization and search redirect.
