Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — One Piece Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — high-reach monetization/search-hijack surface.
• Privacy policy is Google's generic policy, not scoped to this extension; admits data collection & 3rd-party sharing.
• Both install and uninstall URL hijacks redirect to gameograf.com for tracking.
• Two innerHTML DOM-XSS sinks with no CSP amplify XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• install_uninstall_hijack manifest Both onInstalled and uninstall URLs redirect to gameograf.com with UTM params.
• generic_privacy_policy store Privacy URL is Google's own policy (myaccount.google.com); scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• dom_xss_sinks crx innerHTML user-controlled sinks in popup.js and calendar.js with no CSP — DOM-XSS risk.
• no_developer_name store developer_name is empty string; reduces accountability.
• verified_publisher store verified_publisher=true with resolving domain gameograf.com; partial reputation credit.
• newtab_search_engine_count api search_engine_count=1 (google.com only); no multi-search aggregator signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — One Piece Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.36 -> 7.86 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search-provider interaction; paired with newtab override elevates risk.
• https://api.gameograf.com/* medium Scoped host permission to developer API; enables data exfil from newtab context.
• chrome_url_overrides.newtab high Full newtab replacement — high-visibility, every-session monetization surface.
