Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Gamer Anime Girl Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack to gameograf.com — classic monetization shell pattern.
• Two unguarded innerHTML sinks (popup.js, calendar.js) with no CSP — DOM-XSS risk.
• No developer name listed despite verified-publisher status reduces accountability.
• Low install count (197) with newtab override and tracking UTM parameters on every install/uninstall.

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
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• dom_sink_innerhtml_userctrl crx innerHTML sinks in popup.js and calendar.js with no CSP — DOM-XSS exposure.
• no_csp manifest content_security_policy is null; MV3 default applies but innerHTML sinks increase risk.
• verified_publisher store Developer gameograf.com is verified; domain resolves and is not throwaway.
• privacy_policy_third_party_sharing api Policy fetched: scope_extension=true, data_collection=true, third_party_sharing=true, retention=true.
• no_developer_name store developer_name is empty string despite verified_publisher=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Gamer Anime Girl 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 for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled domain only; low standalone risk.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization/data-collection surface.
