Top Risks

• Uninstall URL hijack to chromewallpaper.com — classic monetization-shell pattern.
• Install URL hijack opens 3rd-party domain on every install.
• Privacy policy is Google's generic account policy — does not cover this extension at all.
• NewTab override with free-webmail dev, no developer name, no verified publisher — low accountability.
• No CSP on MV3 extension contacting 8 external hosts including Netflix, YouTube, Instagram.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://chromewallpaper.com/uninstall; textbook monetization-shell exfil hook.
• install_url_hijack manifest onInstalled opens https://chromewallpaper.com/jude-bellingham-wallpaper-football-star-backgrounds.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab for ad/search monetization.
• privacy_policy_generic store PP is Google's own account policy (scope_extension=false, data_collection=true, third_party_sharing=true). +10 privacy.
• free_webmail_no_devname store Developer email cananayartis@gmail.com, developer_name empty, no verified publisher badge.
• js_external_hosts_broad crx 8 external JS hosts: chatgpt.com, chrome.google.com, chromewallpaper.com, google.com, instagram.com, netflix.com, youtube.com, x.com.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit policy hardening.
• new_tab_monetization_override store NewTab override + uninstall hijack + install hijack + chromewallpaper.com operator = monetization shell pattern.

Permissions Breakdown

• search medium Allows reading/modifying search queries; paired with NewTab override raises search-monetization concern.
• chrome_url_overrides.newtab high Replaces every new tab; primary surface for ad-monetization and user tracking in wallpaper shells.
