Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Love Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijack to gameograf.com — confirmed monetization shell pattern.
• NewTab override replaces every new tab; combined with 'search' permission enables search/ad injection.
• Privacy policy is Google's generic account policy — does not scope to this extension; data collection and 3rd-party sharing admitted.
• Free-webmail dev (halilseker3455@gmail.com), no developer name, no business website — unverifiable identity.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → gameograf.com UTM campaign; classic monetization shell.
• install_url_hijack manifest onInstalled opens gameograf.com with tracking params — ad-tech redirect on install.
• newtab_override manifest chrome_url_overrides.newtab set to index.html — every new tab controlled by extension.
• privacy_policy_generic store Policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_no_dev_name store Developer email gmail.com, developer_name empty — unverifiable identity.
• js_external_hosts_broad crx gameograf.com, instagram.com, netflix.com, youtube.com, x.com — excessive for a wallpaper.
• verified_publisher store Verified publisher badge present but does not override monetization shell signals.
• new_tab_monetization_shape manifest NewTab + search permission + uninstall/install hijack to ad-domain = monetization cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Love Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.44 -> 8.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser search API; combined with newtab override enables search hijack.
• chrome_url_overrides.newtab high Replaces every new tab with extension-controlled page — high monetization/hijack surface.
