Top Risks

• Uninstall URL hijack to third-party owhit.com — classic traffic-monetization telemetry pattern.
• Install URL hijack to owhit.com — redirects users to operator-controlled page on install.
• NewTab override with 'search' permission: search-monetization shell pattern, 8 external JS hosts including OpenAI, Netflix, YouTube, Instagram.
• Privacy policy is Google's own policy (not scoped to this extension) yet extension contacts owhit.com — collection undisclosed.
• Free-webmail developer with no verified publisher status and no business domain; accountability near-zero.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; sends user to operator monetization page on removal.
• install_url_hijack crx onInstalled opens https://owhit.com/charlie-brown-pumpkin-live-wallpaper; 3rd-party redirect on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; NewTab replaced on every new tab open.
• broad_js_external_hosts crx 8 external hosts: chat.openai.com, netflix.com, instagram.com, youtube.com, x.com, owhit.com, google.com, chrome.google.com.
• privacy_policy_generic store Policy URL is Google Account policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy.
• free_webmail_developer store Developer email yusufkerem050@gmail.com; no verified publisher; no business domain; developer_name 'Chrome New Tab'.
• search_permission_newtab_combo manifest 'search' permission + newtab override = search monetization shell pattern.
• csp_absent_mv3 manifest content_security_policy null; MV3 has strict default but no explicit CSP declared.

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with newtab override, enables search monetization.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-reach surface for ad injection and search hijacking.
