Top Risks

• Brand impersonation of Surfshark VPN by free-webmail gmail dev with no publisher verification
• proxy permission enables full browser traffic interception/MITM via attacker-controlled servers
• install_url_hijack redirects to neoncloak.space — unknown third-party infrastructure on install
• JS contacts app.myxavpn.pro and neoncloak.space (NL+RU geo) — no relation to real Surfshark
• Privacy policy is Google's generic account policy — not scoped to this extension at all

Evidence

• brand_impersonation store Title 'Surfshark VPN' with dev email kameqoko032@gmail.com; not verified publisher; confirmed_owner=false.
• install_url_hijack crx onInstalled opens https://neoncloak.space/ — same domain as external JS host, unknown third party.
• external_js_hosts crx JS contacts app.myxavpn.pro, neoncloak.space, t.me — none are surfshark.com; NL+RU geo.
• proxy_permission manifest proxy declared — routes all browser traffic; MITM capability with no verified operator.
• generic_privacy_policy store Privacy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• free_webmail_no_dev_name store developer_name empty, developer_email is gmail — no business identity verifiable.
• small_install_high_perm api 91 installs with HIGH-tier proxy permission — tail-attack-surface anomaly.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening declared.

Permissions Breakdown

• proxy high Routes all browser traffic through attacker-controlled proxy; full MITM capability.
