Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Pochacco Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search permission: classic ad-monetization shell replacing every new tab page.
• Uninstall URL hijack to owhit.com: tracks uninstalls via third-party domain.
• Install URL hijack to owhit.com: opens third-party page on install, monetization funnel.
• Privacy policy is generic Google account policy — not scoped to this extension, admits data collection and third-party sharing.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html — replaces every new tab with extension-controlled page.
• uninstall_url_hijack crx setUninstallURL targets https://owhit.com/uninstall — third-party tracking on uninstall.
• install_url_hijack crx onInstalled opens https://owhit.com/pochacco-live-wallpaper/ — third-party monetization funnel.
• privacy_policy_generic store Policy URL is Google's own account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_developer store Developer email tekbatuhan64@gmail.com — free webmail, no verified publisher badge.
• js_external_hosts crx Extension references 8 external hosts including owhit.com, chat.openai.com, major social/media platforms.
• search_permission_newtab_combo manifest search permission + newtab override without broad host_permissions is standard NewTab monetization pattern.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no custom hardening declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Pochacco Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.57 -> 8.07 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; paired with newtab override amplifies monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab with extension page; primary vector for traffic/ad monetization.
