Top Risks

• proxy permission routes ALL browser traffic through shershvpn.space — an unknown Russian-hosted domain controlled by anonymous developer
• Privacy policy is Google's own policy, not scoped to this extension; admits data collection and 3rd-party sharing
• Developer is anonymous (no name, gmail-only), no verified publisher badge, no business presence
• install_url_hijack=true: extension opens 3rd-party URL on install, indicating monetization or tracking behavior
• Only 37 installs with high-impact permission (proxy) — classic tail-attack-surface pattern

Evidence

• proxy_permission manifest proxy declared — can silently reroute all browser HTTP/S traffic to shershvpn.space (RU-hosted)
• install_url_hijack store install_url_hijack=true; extension opens 3rd-party URL on install — monetization/tracking indicator
• generic_privacy_policy store Privacy URL points to Google's account policy (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
• js_external_host_ru crx External JS host shershvpn.space resolves in RU only — single-country, unknown operator
• small_install_high_perm api 37 installs with proxy (HIGH) permission — install_perm_anomaly.small_install_high_perm=true
• no_csp manifest content_security_policy is null on MV3 extension; no CSP protection for popup/background
• wayback_unresolved api Wayback ownership check timed out; cannot confirm domain history or ownership continuity

Permissions Breakdown

• proxy high Allows full rerouting of browser traffic through attacker-controlled servers.
