Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Gorillaz Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic newtab monetization shell fingerprint.
• Install URL hijack to owhit.com — opens 3rd-party page on install.
• NewTab override with 'search' permission enables covert search-provider monetization.
• Privacy policy is Google's generic account policy, not scoped to this extension; admits data collection + 3rd-party sharing.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; 3rd-party monetization shell signal.
• install_url_hijack crx onInstalled opens https://owhit.com/gorillaz-wallpaper; traffic harvesting on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab controlled by extension.
• privacy_policy_generic store Policy URL is Google account policy (479 KB); scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email canb08898@gmail.com; no verified business domain; numbered-alias pattern.
• js_external_hosts crx Extension contacts chatgpt.com, owhit.com, x.com, instagram.com, youtube.com among 7 external hosts.
• search_permission_newtab_combo manifest 'search' permission + newtab override = standard pattern for covert search-engine monetization.
• no_csp manifest content_security_policy is null; no CSP hardening despite MV3 (MV3 default applies but no explicit policy).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Gorillaz Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.27 -> 7.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser's search engine; newtab override amplifies monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab; prime surface for ad injection and search monetization.
