Top Risks

• Uninstall URL hijack to owhit.com — classic monetization shell pattern with persistent tracking on removal.
• Install URL hijack to owhit.com — opens 3rd-party page on install; affiliate/ad-tech fingerprinting.
• New-tab override with free-webmail developer and no verifiable identity — every new tab is under attacker control.
• Privacy policy is Google's own policy, not scoped to this extension, while data_collection and third_party_sharing are true — effectively no disclosure.
• Free-webmail developer (gmail), no verified publisher, no business domain — low accountability, easy abandonment or sale.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — 3rd-party tracking on removal.
• install_url_hijack crx onInstalled opens https://owhit.com/ariana-grande-wallpaper — affiliate/ad-tech redirect at install time.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab served by this extension.
• privacy_policy_generic store Policy URL is Google's account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email yusufkerem050@gmail.com with no business domain; domain_age_ct not queried (free webmail).
• new_tab_monetization_shape crx NewTab + search override + owhit.com install/uninstall hooks = textbook ad-monetization shell.
• js_external_hosts_broad crx JS contacts chatgpt.com, instagram.com, netflix.com, youtube.com, x.com — 8 external hosts, 2 countries.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.

Permissions Breakdown

• search medium Allows manipulation of browser search; medium risk on its own but combined with newtab override raises concern.
• chrome_url_overrides.newtab high Replaces every new tab — prime monetization surface and persistent user reach.
