Top Risks

• NewTab override hijacks every new tab; paired with uninstall+install URL hijack to owhit.com — classic monetization shell.
• Privacy policy is Google's own account policy — not scoped to this extension; admits data collection and third-party sharing (Privacy pillar = 10.0).
• Uninstall and install URL both redirect to owhit.com third-party domain — monetization/tracking funnel confirmed.
• Free-webmail developer (evrenturhane3@gmail.com), no verified publisher, no business website — unverifiable identity.
• External JS hosts include 7 distinct origins (owhit.com, chatgpt.com, instagram.com, x.com, youtube.com, etc.) with no CSP — broad network surface.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — confirmed 3rd-party hijack.
• install_url_hijack manifest onInstalled opens https://owhit.com/gucci-wallpaper — 3rd-party install redirect.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab hijacked by this extension.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email evrenturhane3@gmail.com; no verified publisher badge; no business domain.
• js_external_hosts_broad crx 7 external JS hosts: owhit.com, chatgpt.com, chrome.google.com, google.com, instagram.com, youtube.com, x.com.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
• search_permission_newtab_combo manifest search permission + newtab override is canonical search-monetization shell fingerprint.

Permissions Breakdown

• search medium Allows reading and modifying search queries; combined with newtab override raises monetization risk.
• chrome_url_overrides.newtab high Replaces every new tab page — primary monetization/tracking surface for shell extensions.
