Top Risks

• proxy permission allows full traffic interception/redirection through developer-controlled servers (app.myxavpn.pro, skyproxy.space).
• Free-webmail developer (norkienej@gmail.com), no developer name, no verified publisher — unaccountable operator.
• Privacy policy is Google's own policy (not scoped to this extension); admits data collection and third-party sharing — D(generic+worst-case) clause applies.
• Install URL hijack opens https://skyproxy.space on install; external JS hosts include t.me and app.myxavpn.pro.
• Geo-diversity: JS hosts span CA, NL, RU, US (4 countries) — traffic routed through Russian-geolocated infrastructure.

Evidence

• proxy_permission manifest proxy declared — can reroute all browser traffic to skyproxy.space / app.myxavpn.pro with no accountability.
• free_webmail_no_devname store Developer email norkienej@gmail.com; developer_name empty; no verified publisher badge.
• generic_google_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension; scope_extension=false, data_collection=true, third_party_sharing=true.
• install_url_hijack crx onInstalled opens https://skyproxy.space — third-party URL hijack on install.
• external_js_hosts crx JS contacts: app.myxavpn.pro, skyproxy.space, t.me — unverified third-party endpoints including Telegram.
• geo_diversity_ru api JS host countries: CA, NL, RU, US — Russian-geolocated infrastructure present for a VPN proxy extension.
• small_install_high_perm store 181 installs with HIGH-tier proxy permission — tail attack surface anomaly flagged.
• no_csp manifest content_security_policy is null; MV3 provides strict default but extension has no explicit CSP declared.

Permissions Breakdown

• proxy high Can redirect all browser traffic through attacker-controlled servers; full network interception capability.
• host: https://cloudflare-dns.com/* low Legitimate DNS-over-HTTPS endpoint; consistent with VPN/proxy function.
• host: https://dns.google/* low Legitimate DNS-over-HTTPS endpoint; consistent with VPN/proxy function.
