Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Haunting Grim Reaper Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns HTTP error — policy effectively absent; privacy pillar maxed at 10.
• New-tab override with uninstall URL hijack and install URL hijack: classic monetization shell pattern.
• No developer name listed; MV3 with no CSP raises DOM-XSS risk from innerHTML sink in popup.js.
• Stale 15 months with newtab override and unverifiable privacy policy — elevated long-term risk.

Evidence

• uninstall_url_hijack manifest setUninstallURL to gameograf.com with UTM params — traffic monetization on removal.
• install_url_hijack manifest onInstalled opens gameograf.com with UTM params — monetization on install.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab.
• privacy_policy_fetch_error api privacy_policy_classification.fetched==false (HTTPError) — policy inaccessible, scored +10.
• dom_sink_innerhtml_userctrl crx js/popup.js assigns innerHTML from variable without sanitization — DOM-XSS risk.
• no_developer_name store developer_name is empty string; identity unverifiable beyond email domain.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• maintenance_stale store 15 months since last update; 12-24mo band scores +6.0.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Haunting Grim Reaper Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.15 -> 8.65 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser search engine; combined with newtab override raises monetization concern.
• chrome_url_overrides.newtab high Replaces new-tab page; primary vector for search monetization and user tracking.
• host_permissions: https://api.gameograf.com/* medium Grants fetch access to developer's own API; data sent/received is unaudited.
