Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cinnamoroll Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension; collects/shares data per policy admission.
• Uninstall URL hijack + install URL hijack: both redirect to haberikra.com with tracking params — monetization shell pattern.
• NewTab override combined with 'search' permission enables persistent search monetization on every new tab.
• No developer name listed; verified_publisher flag present but policy is generic Google URL (0c cap applies).

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL -> haberikra.com with utm_campaign=bg&utm_content=uninstall tracking.
• install_url_hijack crx onInstalled opens haberikra.com with utm_source=install tracking — monetization shell pattern.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for all users.
• generic_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's policy, not extension-scoped. data_collection+third_party_sharing true.
• no_developer_name store developer_name is empty string; verified_publisher=true but identity not publicly named.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with no CSP; DOM-XSS risk.
• months_since_update_15 store Last updated May 2025 (15 months); 12-24mo band -> Maintenance +6.0.
• verified_publisher_capped store verified_publisher=true but months_since_update=15 >12mo; 0c cap limits discount to -1.0 on reputation.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cinnamoroll Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 5.42 -> 7.92 (+2.5 cap 2.5).
