Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Chibi Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns connection error — effectively no accessible privacy policy.
• Uninstall and install URL hijack to gameograf.com tracking URLs — monetization pattern.
• NewTab override with 'search' permission — daily-reach search monetization risk.
• Two DOM-XSS sinks (innerHTML from variable) with no CSP — elevated injection risk.

Evidence

• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party tracking).
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install.
• privacy_policy_fetch_failed api fetch_error:ConnectionError on https://api.gameograf.com/gameograf-privacy-policy.html — treated as no policy.
• newtab_override manifest chrome_url_overrides.newtab → newtab.html; combined with search permission = search monetization shape.
• dom_xss_sink crx innerHTML from variable in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_developer_name store developer_name is empty string; reduces accountability.
• verified_publisher store verified_publisher=true mitigates reputation somewhat but does not explain URL hijacks.
• domain_age api gameograf.com first cert 2021-02-03, age 2051 days, 265 certs — established domain, not throwaway.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Chibi Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.55 -> 7.05 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; combined with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* medium Scoped to dev's own API domain; acceptable but enables data exfil to their backend.
• chrome_url_overrides.newtab medium Replaces new-tab page — high-reach, daily user touchpoint, monetization vector.
