Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Momo Ayase DanDaDan Live Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — not scoped to this extension, admits data collection and third-party sharing (privacy pillar maxed).
• NewTab override + search permission = classic ad-monetization shell; uninstall and install URL hijacks to gameograf.com UTM links.
• No developer name listed; verified publisher but no 'Offered by' field — accountability gap.
• No CSP on MV3 extension with innerHTML DOM-XSS sink in popup.js.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab with developer-controlled page.
• uninstall_url_hijack crx setUninstallURL points to gameograf.com with UTM tracking params — monetization signal.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install params — monetization signal.
• generic_google_privacy_policy store Privacy policy URL is Google's own policy — scope_extension=false, data_collection=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; no 'Offered by' accountability on store listing.
• dom_xss_sink_no_csp crx innerHTML assigned from variable in popup.js with csp_present=false — DOM-XSS risk unmitigated.
• stale_extension store 16 months since last update; verified-publisher discount capped at -1.0 due to privacy policy admitting 3rd-party sharing (v3.5 E).
• search_engine_single api Only 1 search engine (google.com) seen — no multi-engine aggregator anomaly; direct provider unclear.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Momo Ayase DanDaDan Live Wallpapers [adware] + malext.io malicious_extension_sentry; score 5.14 -> 7.64 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying/modifying search provider behavior; paired with newtab override raises risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain only; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization surface for this extension type.
