Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Gumball Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic traffic-monetization shell pattern.
• Install URL hijack to owhit.com — monetization redirect on every install.
• New-tab override + search permission = search redirect / ad-monetization surface.
• Privacy policy is Google's own policy (not scoped to this extension); admits data collection and third-party sharing.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; confirms monetization shell pattern.
• install_url_hijack crx onInstalled opens https://owhit.com/gumball-live-wallpaper; third-party install redirect.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab hijacked.
• privacy_policy_generic store Policy URL is Google Account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• developer_identity store gokturksener476@gmail.com, dev name 'Newtab'; free webmail, no business domain, no verified publisher.
• search_permission_newtab_combo manifest search + newtab override is the canonical search-monetization combination.
• js_external_hosts_broad crx References chat.openai.com, instagram.com, netflix.com, youtube.com, x.com, owhit.com — broad external surface.
• csp_absent crx content_security_policy is null; MV3 default CSP applies but no explicit restrictions declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Gumball Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows read access to search terms; medium risk on its own but paired with newtab override it enables search hijacking.
• chrome_url_overrides.newtab high Replaces every new tab; combined with search permission enables monetized search redirect.
