Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Dark Defender Venom Live Wallpaper [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 3rd-party sharing (+10 privacy pillar).
• NewTab override with uninstall and install URL hijacks to gameograf.com — classic traffic-monetization shell pattern.
• No developer name listed; verified publisher badge present but policy is generic Google URL.
• Extension stale 15 months with NewTab override — sustained browser-surface exposure.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for life of install.
• uninstall_url_hijack crx setUninstallURL targets 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
• generic_privacy_policy store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension.
• privacy_policy_classification api scope_extension=false, data_collection=true, third_party_sharing=true — worst-case generic policy.
• dom_sink_innerhtml crx js/popup.js: innerHTML assigned from variable with no CSP guard — DOM-XSS risk.
• no_developer_name store developer_name is empty string; verified_publisher=true but no displayed org name.
• stale_newtab store 15 months since update; NewTab override sustains monetization surface without maintenance signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Dark Defender Venom Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.37 -> 7.87 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; bounded reach.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-frequency monetization surface.
