Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Аво Proxy [browser-hijack] + malext.io malicious_extension_sentry (+2.5, capped).
• proxy permission allows complete rerouting of all browser traffic to usachvpn.su (RU-hosted).
• Free-webmail Gmail developer, no name, no business identity — extremely low accountability.
• Privacy policy is Google's generic account policy — does NOT scope to this extension at all.
• install_url_hijack: extension opens a URL on installation, a monetization/tracking signal.

Evidence

• proxy_permission manifest proxy declared — can intercept and redirect all browser network traffic.
• js_external_host_ru crx External JS host usachvpn.su is Russia-geolocated; traffic routing destination unknown.
• install_url_hijack store install_url_hijack=true: extension opens third-party URL on install.
• privacy_policy_generic store Privacy URL is Google account policy; scope_extension=false, data_collection=true, 3rd_party_sharing=true.
• free_webmail_no_dev_name store Developer email ekugabezu505@gmail.com, no developer name — zero business accountability.
• small_install_high_perm api Only 6 installs with proxy (HIGH-tier) permission — tail attack surface anomaly confirmed.
• no_verified_publisher store Not verified, not featured; no developer domain to evaluate.
• csp_absent_mv3 manifest No CSP declared; MV3 provides some default protection but no explicit policy.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Аво Proxy [browser-hijack] + malext.io malicious_extension_sentry; score 5.61 -> 8.11 (+2.5 cap 2.5).

Permissions Breakdown
