Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sonic Frontiers Starfall Live Wallpaper [adware] (+2.0, capped).
• NewTab override replaces every new tab with developer-controlled page enabling persistent monetization/tracking.
• Uninstall URL hijack and install URL hijack both present — classic traffic-monetization shell pattern.
• External JS hosts include chatgpt.com, instagram.com, youtube.com, x.com — broad social/AI platform reach from a wallpaper extension.
• Privacy policy admits data collection and third-party sharing but no retention period disclosed.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — hijacks every new tab session.
• uninstall_url_hijack crx uninstall_url_hijack=true; target unknown — confirms monetization shell pattern.
• install_url_hijack crx install_url_hijack=true; target unknown — opens 3rd-party URL on install.
• broad_external_hosts crx JS contacts chatgpt.com, instagram.com, x.com, youtube.com — unrelated to wallpaper function.
• no_csp manifest content_security_policy=null; MV3 default CSP applies but no explicit hardening.
• privacy_data_collection_third_party store Policy: scope_extension=true, data_collection=true, third_party_sharing=true, retention=false.
• search_permission_with_newtab manifest 'search' permission + newtab override = monetizable search-redirect capability.
• not_verified_not_featured store verified_publisher=false, is_featured_by_google=false; developer WallExt not verifiable.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sonic Frontiers Starfall Live Wallpaper [adware]; score 4.60 -> 6.60 (+2.0 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab — primary vector for search monetization and persistent user tracking.
