Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sakura Haruno Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy (not scoped to this extension) — admits data collection and 3rd-party sharing: +10.0 privacy.
• Uninstall URL hijack + install URL hijack both redirect to gameograf.com — monetization/tracking pattern.
• NewTab override replaces every new tab; combined with search permission creates search-monetization surface.
• Two innerHTML DOM-XSS sinks with no CSP; no policy to constrain script execution.

Evidence

• privacy_policy_generic store Policy URL is Google's account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets gameograf.com utm tracking URL → +3.0 webstore.
• install_url_hijack crx onInstalled opens gameograf.com utm tracking URL → +2.0 webstore.
• newtab_override manifest chrome_url_overrides.newtab set; NewTab + search permission = monetization shell shape → +2.0 webstore.
• no_csp manifest content_security_policy is null; csp_present=false. MV3 has strict default but innerHTML sinks present increase DOM-XSS risk.
• dom_sink_innerhtml crx Two innerHTML-from-variable sinks in popup.js and calendar.js with no CSP → code_quality +2.0 (FIX B condition met: csp_present==false).
• no_developer_name store developer_name is empty string; manifest name uses __MSG_appName__ placeholder → reputation +1.0.
• verified_publisher store verified_publisher=true; gameograf.com resolves, no stale/CVE/monetization cap triggers → reputation -3.0 applied.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sakura Haruno Naruto Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.51 -> 7.01 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search-provider interaction; combined with newtab override elevates risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces every new tab; prime monetization surface for a theme/wallpaper extension.
