Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Miles Morales Hoodie Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search permission = classic ad-monetization shell pattern.
• Both install and uninstall URL hijack to gameograf.com with UTM tracking.
• No CSP on MV3 extension with innerHTML DOM-XSS sinks in popup.js and calendar.js.
• No developer name listed despite verified publisher badge.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=extension&utm_medium=install.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install.
• no_csp manifest content_security_policy is null; MV3 strict default still applies but no explicit CSP declared.
• dom_xss_sinks crx innerHTML assignments from variables in popup.js and calendar.js — DOM-XSS risk without CSP.
• no_developer_name store developer_name is empty string despite verified_publisher == true.
• new_tab_monetization_pattern store NewTab category + search permission + UTM install/uninstall hooks = monetization shell fingerprint.
• verified_publisher store verified_publisher=true; domain resolves, not throwaway; mitigates reputation somewhat.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Miles Morales Hoodie Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.08 -> 6.58 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search functionality; combined with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* medium Scoped to dev's own API domain; used for wallpaper content and privacy policy.
• chrome_url_overrides.newtab medium Replaces every new tab — high-reach surface, monetization vector for this category.
