Top Risks

• Uninstall and install URL hijack both redirect to gameograf.com with UTM tracking — confirmed monetization shell pattern.
• New-tab override replaces every tab with developer-controlled page; paired with search permission for search monetization.
• Privacy policy is Google's own policy (not scoped to this extension) — admits data collection and third-party sharing with no extension-specific disclosure.
• Free-webmail developer (Gmail) with no verified publisher, no business domain, and no business website.
• JS external hosts include Instagram, Netflix, YouTube, X — broad social/media host contact pattern beyond stated wallpaper function.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets gameograf.com with ovkas UTM params — third-party monetization redirect.
• install_url_hijack crx onInstalled opens gameograf.com with same UTM tracking — install-time redirect to monetization site.
• newtab_override manifest chrome_url_overrides.newtab set to index.html — every new tab is developer-controlled.
• generic_privacy_policy store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true — unscoped admission.
• free_webmail_developer store Developer email halilibrahimseker125@gmail.com — no business domain, not verified publisher.
• js_external_hosts_broad crx Extension contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — unrelated to wallpaper function.
• newtab_monetization_shape manifest NewTab + search permission + install/uninstall UTM hijack = classic monetization-shell fingerprint.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension with external host contacts.

Permissions Breakdown

• search medium Allows querying the browser's search engine; combined with newtab override enables search monetization.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page; primary monetization surface for this shell.
