Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Astra Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack to gameograf.com utm-tagged page — traffic monetization pattern.
• NewTab override replaces browser new tab with developer-controlled page on every open.
• No CSP declared (MV3): innerHTML sinks in popup.js and calendar.js lack XSS mitigations.
• No developer name listed despite verified publisher status — reduced accountability.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• newtab_override manifest chrome_url_overrides.newtab = newtab.html — every new tab is developer-controlled.
• no_csp manifest content_security_policy is null; two innerHTML DOM-XSS sinks present with no mitigation.
• dom_sink_innerhtml_userctrl crx innerHTML sinks in js/popup.js and js/calendar.js; no CSP and no obfuscation.
• no_developer_name store developer_name is empty string despite verified_publisher == true.
• privacy_policy_third_party_sharing api Policy discloses data collection, retention, and third-party sharing scoped to extension.
• verified_publisher store Verified publisher badge present; domain resolves; not throwaway.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Astra Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.81 -> 5.31 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search engine; relevant to NewTab category.
• chrome_url_overrides.newtab medium Replaces new tab page — primary function but a monetization-risk surface.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
