Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Aquarium Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — primary surface for search hijack and ad monetization.
• Uninstall and install URL hijacks redirect users to developer marketing pages.
• No CSP declared (MV3 default mitigates somewhat but innerHTML XSS sink in calendar.js still exploitable).
• Developer name missing; only email identity available, reducing accountability.

Evidence

• 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/?p=33054?utm_source=extension&utm_medium=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=33054?utm_source=extension&utm_medium=install
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js with no CSP guard — DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but innerHTML sink remains unmitigated.
• developer_name_missing store developer_name is empty string; identity relies solely on email support@gameograf.com.
• third_party_sharing_disclosed api Privacy policy confirms data collection and third-party sharing scoped to extension.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway — partial trust signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Aquarium Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.81 -> 5.31 (+2.5 cap 2.5).

Permissions Breakdown

• alarms low Schedule background tasks; low standalone risk.
• storage low Local data persistence only.
• search medium Can read and manipulate search queries; elevated for a wallpaper/NewTab extension.
• chrome_url_overrides.newtab high Replaces every new tab; prime surface for search hijack and ad monetization.
• host_permissions: https://api.gameograf.com/* medium Scoped to dev domain; allows outbound data transmission to developer server.
