Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Deadpool Bathing Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic monetization shell pattern.
• Privacy policy URL unreachable (fetch error); no scoped data handling disclosure.
• No CSP declared (MV3, not penalized by v2b, but innerHTML sinks with no CSP elevates XSS risk).
• Developer name missing; verified publisher but no 'Offered by' display name.

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
• privacy_policy_fetch_error api Privacy policy URL returned HTTPError; policy not assessable — treated as unfetched.
• dom_xss_sink crx innerHTML assignments from variables in popup.js and calendar.js with no CSP guard.
• no_developer_name store developer_name is empty string; 'Offered by' field missing from listing.
• verified_publisher store verified_publisher=true; domain gameograf.com resolves, age 2051 days, 265 certs.
• search_permission_newtab_combo manifest 'search' permission + newtab override enables query interception on every new tab open.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Deadpool Bathing Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 5.27 -> 7.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override it can redirect queries.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for monetization and data collection.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited external reach.
