Top Risks

• Uninstall URL hijack to owhit.com — classic monetization-shell pattern tracking user churn.
• Install URL hijack to owhit.com on every install — exfils install event to third-party domain.
• Privacy policy is Google's own policy (myaccount.google.com) — not scoped to this extension; admits data collection & 3rd-party sharing.
• Gmail developer with no verified publisher, no business domain; free-webmail floor at 7.5 reputation.
• NewTab override + search permission with no CSP; MV3 default CSP applies but extension contacts 8 external hosts via JS.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://owhit.com/uninstall; third-party tracking on uninstall.
• install_url_hijack crx onInstalled opens https://owhit.com/chiikawa-wallpaper; exfils install event to third-party.
• privacy_policy_generic store PP is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — triggers +10.0 privacy.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab with extension-controlled page.
• free_webmail_developer store Developer email yusufkerem050@gmail.com; no verified publisher, no business website; reputation floor 7.5.
• js_external_hosts crx 8 external hosts referenced in JS: owhit.com, chatgpt.com, youtube.com, instagram.com, netflix.com, x.com, google.com, chrome.google.com.
• search_permission_newtab_combo manifest search permission + newtab override = search monetization surface; +2.0 Webstore (search-provider override).
• no_csp manifest content_security_policy is null; MV3 provides defaults but no explicit CSP declared.

Permissions Breakdown

• search medium Allows overriding search provider; medium risk on its own but paired with newtab override amplifies concern.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page; high monetization and surveillance surface.
