Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Donald Duck Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic adware telemetry/tracking pattern.
• Install URL hijack to owhit.com — captures install events on third-party domain.
• Privacy policy is Google's own policy, not scoped to this extension; data collection and 3rd-party sharing admitted without extension-specific disclosure.
• NewTab override with search permission and 8 external JS hosts including social/streaming platforms — monetization shell pattern.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL -> https://owhit.com/uninstall; third-party operator tracking on uninstall.
• install_url_hijack crx onInstalled opens https://owhit.com/donald-duck-wallpaper; third-party install capture.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab for all users.
• external_js_hosts crx 8 external hosts: owhit.com, chatgpt.com, google.com, instagram.com, netflix.com, youtube.com, x.com, chrome.google.com.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true — admits collection without scoping.
• free_webmail_developer store Developer email yusufkerem050@gmail.com; no verified publisher, no business domain.
• new_tab_monetization_pattern crx NewTab + search permission + install/uninstall hijack to owhit.com matches ad-monetization shell fingerprint.
• no_csp manifest content_security_policy is null; MV3 provides default but no explicit CSP declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Donald Duck Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.34 -> 7.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding default search engine behavior; combined with newtab override raises hijack risk.
• chrome_url_overrides.newtab medium Replaces every new tab page; primary vector for ad-monetization and search hijacking.
