Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Jimin 지민 Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com — classic low-quality NewTab monetization shell pattern (+3.0 Webstore).
• Install URL hijack to owhit.com — redirects users on install to third-party site (+2.0 Webstore).
• Privacy policy is Google's own generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) → +10.0 Privacy.
• Free-webmail developer (gmail) with no verified business identity, no featured badge → Reputation floor 7.5.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL points to https://owhit.com/uninstall — third-party monetization shell.
• install_url_hijack crx onInstalled opens https://owhit.com/jimin--wallpaper — redirects user on install to third party.
• newtab_override manifest chrome_url_overrides.newtab=index.html replaces every new-tab page for all users.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_dev store Developer email canb08898@gmail.com — free webmail, no verified business, no featured badge.
• js_external_hosts crx Extension references owhit.com alongside chatgpt.com, instagram.com, youtube.com, x.com — broad external reach.
• search_permission_newtab manifest search permission combined with newtab override enables search-provider manipulation.
• no_csp crx content_security_policy is null (csp_present=false); MV3 default mitigates eval but not all injection risks.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Jimin 지민 Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding or querying the browser search provider; medium risk for a NewTab extension.
• chrome_url_overrides.newtab medium Replaces every new-tab page with extension content; classic monetization/tracking vector.
