Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cyborg Tiger Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL returns fetch error — policy is effectively unavailable, rated 10/10 privacy risk.
• NewTab override with uninstall/install URL hijack to gameograf.com — monetization shell pattern.
• No CSP declared (MV3) — dom_sink_innerhtml_userctrl findings in popup.js and calendar.js elevate XSS risk.
• Developer name missing; no 'Offered by' display; adds identity accountability gap.

Evidence

• privacy_policy_fetch_error api Privacy policy URL returned HTTPError; policy is unfetchable, treated as unavailable → privacy pillar 10.0.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf — monetization redirect on uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install — install redirect to 3rd-party URL.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js and js/calendar.js with no CSP to mitigate.
• no_csp manifest content_security_policy is null; csp_present==false on MV3 extension with DOM sinks present.
• verified_publisher store Developer is verified publisher; caps reputation floor at 2.0 but no featured badge.
• developer_name_missing store developer_name is empty string; no 'Offered by' accountability signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cyborg Tiger Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 5.28 -> 7.78 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; core monetization vector for this category.
