Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime sparkle butterfly live wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override combined with 'search' permission: classic search-monetization shell pattern.
• Both install and uninstall URL hijacks redirect to developer site with UTM tracking.
• Two innerHTML DOM-XSS sinks with no CSP; csp_present==false amplifies XSS risk.
• No developer name listed; verified publisher status mitigates but reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new-tab page for the user.
• search_permission manifest Declared 'search' permission alongside newtab override — monetization-oriented capability combo.
• install_uninstall_url_hijack crx onInstalled opens gameograf.com with UTM params; setUninstallURL points to same domain.
• dom_xss_sinks_no_csp crx Two innerHTML sinks (popup.js, calendar.js) with csp_present==false; DOM-XSS risk elevated per FIX B.
• verified_publisher store Extension has verified publisher badge; reduces reputation risk but does not eliminate monetization concern.
• privacy_policy_adequate api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• no_cve_findings crx jquery 3.7.1 bundled; no CVEs detected in cve_findings_raw. CVE pillar = 0.
• new_tab_monetization_shape store Anime wallpaper theme with newtab+search override and UTM-tracked install/uninstall matches traffic-monetization pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Anime sparkle butterfly live wallpaper [adware] + malext.io malicious_extension_sentry; score 3.41 -> 5.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; combined with newtab override raises search monetization concern.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search monetization in wallpaper/theme shells.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
