Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Monster Hulk (Marvel Rivals) Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall AND install URL hijack both redirect to gameograf.com with UTM tracking — clear monetization shell.
• New-tab override combined with 'search' permission enables search monetization on every new tab.
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing.
• Free-webmail Gmail developer with no verified publisher badge; gameograf.com UTM fingerprint indicates fan-content churn operation.

Evidence

• install_url_hijack manifest onInstalled opens gameograf.com with utm_source=ovkas — affiliate/monetization redirect on install.
• uninstall_url_hijack manifest setUninstallURL points to gameograf.com with UTM params — traffic monetization on uninstall.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab silently.
• generic_privacy_policy store Policy URL is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• free_webmail_developer store Developer email halilseker3455@gmail.com — numbered alias on free webmail, no business domain.
• js_external_hosts_broad crx Contacts gameograf.com + Instagram + Netflix + YouTube + X.com — far beyond wallpaper function.
• fan_content_shell store Title references Marvel Rivals IP; dev domain gameograf.com is a game-portal shell pattern.
• no_rating_low_installs store 414 installs, 0 rating — no trust signals; tail-install monetization shell profile.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Monster Hulk (Marvel Rivals) Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.25 -> 7.75 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows interaction with Chrome search functionality; paired with newtab override raises monetization concern.
• chrome_url_overrides.newtab medium Replaces new-tab page; core mechanism for search monetization in wallpaper/fan-content shells.
