Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Jujutsu Kaisen Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com — confirmed monetization shell pattern.
• NewTab override with 'search' permission enables search-query interception and ad-revenue harvesting.
• Privacy policy is Google's own generic policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• No developer name; manifest uses __MSG__ placeholders suggesting localization shell with minimal real content.

Evidence

• install_and_uninstall_url_hijack manifest Both onInstalled and uninstall URLs point to gameograf.com with UTM tags — textbook monetization shell.
• newtab_override_with_search manifest chrome_url_overrides.newtab + 'search' permission; NewTab override replaces every new tab for ad injection.
• generic_google_privacy_policy store Privacy policy URL is myaccount.google.com/privacypolicy — not scoped to this extension; data_collection+third_party_sharing=true.
• js_external_hosts_broad crx JS contacts gameograf.com, google.com, instagram.com, netflix.com, youtube.com, x.com — 6 external hosts across 2 countries.
• no_developer_name store developer_name is empty string; manifest name/description are __MSG__ placeholders only.
• verified_publisher store Extension carries verified_publisher=true from ovkas.com (age 1086 days, resolves, 80 certs).
• no_csp manifest content_security_policy is null (csp_present=false); MV3 default applies but no explicit hardening.
• new_tab_monetization_pattern crx NewTab override + install/uninstall hijack + UTM-tagged redirect to gameograf.com = monetization shell fingerprint.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Jujutsu Kaisen Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.87 -> 8.37 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; combined with NewTab override amplifies monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab — primary surface for ad-monetization and search hijacking.
