Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cristiano Ronaldo 4K Live Video Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com — clear monetization shell pattern.
• New-tab override replaces every new tab; combined with 'search' permission enables search-revenue capture.
• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and 3rd-party sharing.
• JS external hosts include social/streaming platforms (Instagram, Netflix, YouTube, X) with no functional justification.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → gameograf.com with UTM tracking params; textbook monetization redirect.
• install_url_hijack crx onInstalled opens gameograf.com with identical UTM params; dual hijack confirms monetization intent.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab served by extension.
• generic_privacy_policy store Policy URL is Google's own privacy page; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• external_host_mismatch crx JS contacts instagram.com, netflix.com, youtube.com, x.com — unrelated to a Ronaldo wallpaper newtab function.
• fan_content_shell store Celebrity-themed wallpaper NewTab with search override and dual UTM hijack matches fan-content/theme shell pattern (+1.5).
• featured_badge store is_featured_by_google=true grants -2.0 reputation discount but does not offset monetization or privacy violations.
• csp_absent manifest content_security_policy=null on MV3; no additional CVE findings so v2(b) MV3 exemption applies — no network penalty added.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cristiano Ronaldo 4K Live Video Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.27 -> 7.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; combined with newtab override amplifies monetization risk.
• chrome_url_overrides.newtab high Replaces new-tab page; primary mechanism for search monetization and ad injection.
