Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Grok AI [divergent] + malext.io malicious_extension_sentry (+2.5, capped).
• Gmail dev (joldeveloply@gmail.com) with no developer name — unverifiable operator identity impersonating 'Grok AI' brand.
• Privacy policy is Google's generic account policy — no scope to this extension; policy admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacks declared — classic traffic-monetization shell pattern.
• 6 external JS hosts on easytool.dev subdomain (chatgpt-5, deepseek-ai, gemini-2, grok-3, grok-ai, perplexity-ai) loaded remotely — supply-chain risk.

Evidence

• free_webmail_dev_no_name store Developer email joldeveloply@gmail.com; developer_name is empty. No verifiable business identity.
• install_uninstall_url_hijack crx Both uninstall_url_hijack and install_url_hijack are true — monetization shell fingerprint.
• external_js_hosts crx 6 easytool.dev subdomains loaded as external JS: chatgpt-5, deepseek-ai, gemini-2, grok-3, grok-ai, perplexity-ai.
• generic_google_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension; collects+shares data.
• no_csp_dom_xss_sink crx csp_present=false AND dom_sink_innerhtml_userctrl in iframe-service-D2VojyOp.js — XSS risk amplified.
• is_featured_by_google store Extension carries Google Featured badge, partially offsetting reputation concern.
• ai_extension_multi_provider_hosts crx Extension hosts content from 6 AI-brand subdomains under single easytool.dev operator — aggregator shell pattern.
• manifest_localized_name_desc crx manifest_name=__MSG_appName__ and manifest_description=__MSG_shortDesc__ — store name relies entirely on locale strings.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Grok AI [divergent] + malext.io malicious_extension_sentry; score 5.30 -> 7.80 (+2.5 cap 2.5).
