Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Amazon Weight Converter [divergent] + malext.io malicious_extension_sentry (+2.5, capped).
• Brand impersonation: dev is Gmail-only, confirmed_owner=false, uses Amazon brand without authorization.
• Privacy policy admits data collection + third-party sharing but is NOT scoped to this extension — worst-case privacy posture.
• Free-webmail developer (Gmail) with no verified business identity; 10xprofit.io domain not validated.
• innerHTML DOM-XSS sink in content.js with no CSP — any data Amazon pages expose could be misused.

Evidence

• brand_impersonation store brand_mention.is_impersonation=true; developer_domain=gmail.com; confirmed_owner=false for Amazon brand.
• privacy_policy_d_clause api Policy fetched; scope_extension=false, data_collection=true, third_party_sharing=true → D-clause: score +10.0.
• free_webmail_developer store Developer email 10xprofitio@gmail.com; no verified publisher badge; no featured badge.
• dom_xss_sink_no_csp crx innerHTML user-controlled in content.js; csp_present=false raises XSS risk per FIX B.
• install_url_hijack manifest install_url_hijack=true targeting welcome.html; opens page on install.
• external_js_host crx js_external_hosts=[app.10xprofit.io]; unverified third-party domain contacts extension.
• maintenance_stale store months_since_update=7; falls in 3-6 month band (+1.5) or 6-12 band (+3.5); using 7mo → +3.5.
• very_low_install_count store Only 6 installs; near-zero community validation; tail-attack-surface anomaly noted.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Amazon Weight Converter [divergent] + malext.io malicious_extension_sentry; score 4.66 -> 7.16 (+2.5 cap 2.5).
