Top Risks

  • Brand impersonation of TunnelBear VPN — free-webmail dev with 145 installs, no verified publisher status.
  • Install URL hijack opens skorostvpn.space on install — classic drop-traffic monetization shell.
  • proxy permission routes ALL browser traffic through developer-controlled infrastructure.
  • Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and third-party sharing.
  • No developer name and free-webmail (gmail) developer with no business domain adds accountability risk.

Evidence

  • install_url_hijack crx onInstalled opens https://skorostvpn.space/ — monetization/tracking redirect on install.
  • brand_impersonation_name store Extension named 'Tunnel-Bear VPN' mimicking TunnelBear brand; developer is free-webmail gmail account, not McAfee/TunnelBear.
  • free_webmail_no_dev_name store Developer email namikkm13@gmail.com, developer_name empty — no accountable identity.
  • generic_privacy_policy api Privacy policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true — not scoped to extension.
  • proxy_permission manifest proxy declared — allows full rerouting of browser network traffic, highest-impact VPN capability.
  • external_host_skorostvpn crx js_external_hosts includes skorostvpn.space — unknown third-party domain, also install hijack target.
  • small_install_high_perm store 145 installs with HIGH-tier proxy permission — install_perm_anomaly.small_install_high_perm=true.
  • host_geo_diversity api JS hosts span CA, RU, US — includes Russian-geolocated host (skorostvpn.space), 3 countries.

Permissions Breakdown

  • proxy high Allows rerouting all browser traffic through an arbitrary proxy — maximum network interception capability.
  • https://cloudflare-dns.com/* medium DNS-over-HTTPS host access; necessary for a VPN/proxy tool but still a sensitive network endpoint.
  • https://dns.google/* medium DNS-over-HTTPS host access; same rationale as cloudflare-dns.
