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).
• Privacy policy is Google's generic policy (not scoped to this extension) while admitting data collection and 3rd-party sharing — +10 privacy pillar.
• New-tab override with uninstall/install URL hijacks to gameograf.com UTM tracking — classic monetization shell pattern.
• No developer name listed despite verified publisher status; adds accountability gap.
• Extension stale 16 months (>12mo) with newtab override and UTM-tracked install/uninstall hooks — ongoing reach risk.

Evidence

• generic_privacy_policy api Privacy URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx dom_sink_innerhtml_userctrl in js/popup.js with csp_present=false.
• no_developer_name store developer_name is empty string despite verified_publisher=true.
• maintenance_stale store Last updated May 2025; months_since_update=16 (>12mo band = +6.0 maintenance).
• verified_publisher store verified_publisher=true; discount capped at -1.0 due to months_since_update>18 proximity (16mo, borderline) — applied standard -3.0 then adjusted for no-name gap.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — One Piece Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search; combined with newtab override enables search provider manipulation.
• chrome_url_overrides.newtab medium Replaces every new tab with extension page — high reach, monetization vector.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low lateral risk.
