Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cristiano Ronaldo Legend Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override is primary monetization surface; tracks install/uninstall events via UTM-tagged redirects to gameograf.com.
• Uninstall and install URL hijacks redirect to developer site with tracking parameters.
• Two innerHTML DOM-XSS sinks with no CSP to mitigate exploitation of user-controlled data.
• No developer name listed; 'Offered by' field blank reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP present to mitigate DOM-XSS.
• no_developer_name store developer_name is empty string; 'Offered by' field missing reduces identity accountability.
• verified_publisher store Extension has verified_publisher=true; partial reputation credit applied.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true. Adequate.
• new_tab_monetization_pattern manifest search permission + newtab override + install/uninstall tracking URLs = canonical ad-monetization wallpaper shell.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cristiano Ronaldo Legend Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 3.04 -> 5.54 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider behavior; combined with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface for this category.
