Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kaiju No.8 Mission Recon Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new tab; paired with 'search' permission enables search traffic monetization via gameograf.com.
• Uninstall and install URL both redirect to gameograf.com with tracking UTM params — confirmed monetization shell pattern.
• Privacy policy is Google's generic account policy: scope_extension=false, data_collection=true, third_party_sharing=true — worst-case classification.
• Free-webmail developer (gmail), no developer name, no business website — unverifiable identity with verified_publisher badge.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → gameograf.com with ovkas UTM params; classic monetization shell.
• install_url_hijack manifest onInstalled opens gameograf.com with same ovkas UTM params — double URL hijack confirmed.
• newtab_override manifest chrome_url_overrides.newtab=index.html; every new tab replaced for traffic monetization.
• privacy_policy_generic store Policy is Google account policy: scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_no_devname store Developer email halilseker3455@gmail.com, developer_name empty, no business domain.
• js_external_hosts_anomalous crx Extension contacts Netflix, Instagram, YouTube, X, Google — broad platform reach beyond wallpaper function.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
• verified_publisher_free_webmail store verified_publisher=true but developer domain is gmail.com; discount capped per invariant 0c/0e rules.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kaiju No.8 Mission Recon Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 6.24 -> 8.74 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search provider interaction; paired with newtab override elevates search hijack risk.
• chrome_url_overrides.newtab high Replaces new-tab page; core mechanism for traffic monetization and search redirect.
