Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Aurora Winter Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack to developer domain — monetization shell pattern.
• Uninstall URL hijack fires to gameograf.com with UTM tracking on every removal.
• Install URL hijack fires to gameograf.com with UTM tracking on every install.
• No developer name listed; 'search' permission + newtab override creates ad-redirect risk surface.

Evidence

• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?p=32962?utm_source=extension&utm_medium=uninstall
• install_url_hijack manifest onInstalled opens https://gameograf.com/?p=32962?utm_source=extension&utm_medium=install
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; paired with 'search' permission.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• dom_sink_innerhtml_userctrl crx js/calendar.js innerHTML sink without CSP; DOM-XSS risk if calendar data is attacker-controlled.
• no_developer_name store developer_name field is empty string; accountability gap.
• verified_publisher store verified_publisher=true, gameograf.com resolves, not throwaway — reputation partially mitigated.
• privacy_policy_adequate api Policy fetched, scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Aurora Winter Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.14 -> 6.64 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can read/modify search queries; paired with newtab override raises monetization concern.
• alarms low Scheduling only; low standalone risk.
• storage low Local data persistence; no cross-origin concern alone.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-touch surface for monetization/redirect.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; no broad host access.
