Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Радмин VPN [browser-hijack] + malext.io malicious_extension_sentry (+2.5, capped).
• proxy permission routes ALL browser traffic through developer-controlled usachvpn.su (RU-hosted); full MITM capability.
• Privacy policy is Google's generic policy — not scoped to this extension, admits data collection and third-party sharing.
• Developer is anonymous (no name, free-webmail Gmail, no verified publisher), raising accountability risk.
• install_url_hijack=true: extension opens a third-party URL on install without user consent.

Evidence

• proxy_permission manifest proxy declared — can silently redirect all HTTP/S traffic through usachvpn.su (Russia).
• external_host_ru crx js_external_hosts: [usachvpn.su]; host_geo_diversity country_count=1 (RU only).
• install_url_hijack store install_url_hijack=true; extension navigates user to third-party URL on installation.
• generic_privacy_policy api Privacy policy is Google account policy (479 KB); scope_extension=false, data_collection=true, third_party_sharing=true.
• anonymous_developer store developer_name empty, free-webmail Gmail, no verified publisher, no business domain.
• small_install_high_perm api install_perm_anomaly: 135 installs, has_high_tier_permission=true, small_install_high_perm=true.
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension.
• no_code_findings crx code_findings_raw empty, obfuscation_score=0.0; JS surface clean but proxy capability is inherent risk.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Радмин VPN [browser-hijack] + malext.io malicious_extension_sentry; score 5.89 -> 8.39 (+2.5 cap 2.5).

Permissions Breakdown

• proxy high Can redirect all browser traffic through arbitrary SOCKS5/HTTP proxies; full network interception capability.
