Top Risks

• NewTab override hijacks every new tab via yowgames.com shell pattern with uninstall URL redirect.
• Install URL hijack opens yowgames.com on install — third-party traffic monetization indicator.
• Privacy policy is generic Google account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Free-webmail developer (ersanahmet83@gmail.com) with no verified business identity.
• New-tab override with monetization shape: 8 hardcoded external hosts including social/streaming platforms.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html replaces every new tab page.
• generic_privacy_policy store Policy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_dev store Developer email ersanahmet83@gmail.com; no business domain or verified publisher badge.
• external_hosts crx 8 JS external hosts including yowgames.com, chat.openai.com, instagram, netflix, youtube, x.com.
• game_portal_shell crx yowgames.com appears in install/uninstall URLs and JS hosts — game-portal shell pattern.
