Top Risks

• Uninstall URL hijack to yowgames.com and install URL hijack — classic monetization shell pattern.
• New-tab override (chrome_url_overrides.newtab) replaces every new tab; combined with 'search' permission creates search-hijack vector.
• Privacy policy is Google's own generic policy (scope_extension=false, admits data collection + third-party sharing) — worst-case privacy disclosure.
• Free-webmail developer (gmail) with no verified publisher status and no business domain; low accountability.
• Extension contacts 8 external hosts (yowgames.com, social platforms, OpenAI) with no CSP, expanding network attack surface.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL targets https://yowgames.com/uninstall — 3rd-party monetization domain.
• install_url_hijack manifest onInstalled opens https://yowgames.com/nyan-cat-live-wallpaper — 3rd-party redirect on install.
• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab controlled by extension.
• generic_privacy_policy store Policy is Google's account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_developer store Developer email poyrazolcay62@gmail.com; no verified publisher, no business domain.
• js_external_hosts crx 8 external hosts referenced including yowgames.com, chat.openai.com, instagram.com, netflix.com, x.com.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit restriction on network calls.
• search_permission_plus_newtab manifest 'search' permission combined with newtab override; functional search-hijack capability present.

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with newtab override creates search-hijack surface.
• chrome_url_overrides.newtab medium Replaces every new-tab page with extension-controlled HTML; core of monetization shell pattern.
