Top Risks

• Uninstall URL hijack to owhit.com — classic monetization shell pattern used to track churn and serve ads.
• Install URL hijack to owhit.com — opens 3rd-party page on install, fingerprinting and ad-delivery risk.
• Privacy policy is Google's generic account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• NewTab override + search permission with gmail dev and no verified publisher — search-hijacking monetization pattern.
• Developer email is free webmail (gmail), dev name 'playgames' with no business website; no accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab with extension content.
• search_permission manifest search permission declared alongside newtab override — search hijack capability.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.

• js_external_hosts crx References chatgpt.com, instagram.com, x.com, youtube.com, owhit.com — multi-origin link farm in newtab.
• csp_absent_mv3 manifest content_security_policy is null; no explicit CSP declared despite external host references.

Permissions Breakdown
