Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Arsenal FC Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search override: classic ad-monetization shell pattern replacing new-tab and search provider.
• Uninstall and install URL hijacks both active — affiliate/monetization tracking on every lifecycle event.
• bit.ly short-link in JS external hosts: affiliate/cloaking redirector with opaque destination.
• No CSP present (MV3) with innerHTML DOM-XSS sink in popup.js — XSS risk if data is attacker-influenced.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM tracking params on uninstall.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking params.
• affiliate_hit_bitly crx bit.ly in js_external_hosts — generic short-link redirector used for affiliate/cloaking.
• dom_sink_innerhtml crx innerHTML assignment from variable in popup.js with no CSP — DOM-XSS sink.
• no_developer_name store developer_name is empty string in listing.
• verified_publisher store Verified publisher badge present (gameograf.com resolves, not throwaway).
• privacy_policy_complete api Privacy policy fetched, scoped to extension, covers collection/retention/third-party sharing.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Arsenal FC Wallpapers [adware] + malext.io malicious_extension_sentry; score 3.17 -> 5.67 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding the browser search provider — monetization risk in a NewTab shell.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization surface for this category.
