Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Tanjiro Crimson Nichirin Kimetsu No Yaiba Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall and install URL hijack both redirect to gameograf.com — clear monetization shell pattern.
• New-tab override with free-webmail dev account and no verified publisher identity.

• Free-webmail developer (gmail) with no business website; reputation floor triggered.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL points to gameograf.com with UTM tracking params tied to 'ovkas'.
• install_url_hijack manifest onInstalled opens gameograf.com with same UTM params — dual hijack monetization pattern.
• newtab_override manifest chrome_url_overrides.newtab set to index.html; replaces every new-tab page for monetization.
• privacy_policy_generic store Policy URL is Google Account privacy page (scope_extension=false, data_collection=true, third_party_sharing=true) — D rule: +10.0.
• free_webmail_dev store Developer email aliolga956@gmail.com — free webmail, no business domain, reputation floor >= 7.5.
• js_external_hosts crx 6 external hosts including gameograf.com, Netflix, Instagram, YouTube, X — broad reach for 61-install extension.
• game_portal_shell store gameograf.com is a game portal; uninstall+install hijack to same domain confirms monetization shell pattern (+2.0+3.0+3.0).
• no_csp manifest content_security_policy is null on MV3 extension with external JS hosts — no script execution guardrails.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Tanjiro Crimson Nichirin Kimetsu No Yaiba Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.24 -> 7.74 (+2.5 cap 2.5).
