Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Pokemon Family Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new-tab page with install/uninstall URL tracking via UTM-tagged gameograf.com redirects.
• Uninstall and install URL hijacks to 3rd-party domain indicate monetization shell pattern.
• Two DOM-XSS innerHTML sinks (popup.js, calendar.js) with no CSP present to mitigate.
• No developer name listed; verified publisher but anonymous 'offered by' reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=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; MV3 default applies but no explicit script-src restriction.
• verified_publisher store Verified publisher badge present for gameograf.com; domain resolves, not throwaway.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, and 3rd-party sharing.
• no_developer_name store developer_name field is empty string — no 'Offered by' visible in listing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Pokemon Family Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.86 -> 5.36 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/overriding search provider; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; narrow host access.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary surface for monetization and data collection.
