Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — DanDaDan Takakura Ken Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL both hijack to gameograf.com ad-tech domain — confirmed traffic monetization shell.
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, 3rd-party sharing=true) — worst-case privacy.
• NewTab override combined with 'search' permission routes all new-tab traffic through developer-controlled page.
• No developer name; extension contacts 5 major social/streaming domains (instagram, netflix, youtube, x, google) from newtab.

Evidence

• uninstall_url_hijack manifest setUninstallURL → gameograf.com with utm_source=ovkas; confirmed ad-tech redirect on uninstall.
• install_url_hijack manifest onInstalled opens gameograf.com with utm tracking params; monetization shell pattern confirmed.
• newtab_override manifest chrome_url_overrides.newtab = index.html; replaces every new tab with developer-controlled page.
• privacy_policy_generic store Policy URL is Google's own account policy; scope_extension=false, data_collection=true, 3rd_party_sharing=true.
• js_external_hosts_broad crx JS contacts gameograf.com, instagram.com, netflix.com, youtube.com, x.com — 5 unrelated major domains from newtab.
• no_developer_name store developer_name is empty string; accountability gap despite verified_publisher=true.
• verified_publisher store verified_publisher=true; partial reputation credit but does not offset monetization hooks.
• csp_absent manifest content_security_policy is null; MV3 default CSP applies but no extension-specific policy declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — DanDaDan Takakura Ken Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.41 -> 7.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying and potentially overriding search; paired with newtab override elevates risk.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization vector for gameograf.com traffic.
