Top Risks

• proxy permission routes ALL browser traffic through attacker-controlled servers (app.myxavpn.pro, nimbusshield.space)
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing
• Install URL hijack opens nimbusshield.space on install — classic monetization/tracking shell pattern
• Developer is anonymous (no name, free Gmail, no verified publisher) with only 10 installs — tail-attack-surface risk
• JS contacts Russian (RU) and Dutch (NL) hosts including Telegram (t.me) with no stated justification

Evidence

• proxy_permission manifest proxy declared — can silently reroute all browser traffic to app.myxavpn.pro / nimbusshield.space.
• install_url_hijack crx onInstalled opens https://nimbusshield.space/ — classic monetization/tracking redirect.
• external_js_hosts crx JS contacts app.myxavpn.pro, nimbusshield.space, t.me — 3 distinct external domains incl. Telegram.
• generic_privacy_policy store Policy is Google account policy (scope_extension=false, data_collection=true, third_party_sharing=true).
• anonymous_developer store No developer name, free Gmail address, no verified publisher badge, 10 installs.
• free_webmail_dev store kristi.tis@gmail.com — free webmail, no business domain, no verified identity.
• small_install_high_perm api install_perm_anomaly: 10 installs + proxy (HIGH) — tail-attack-surface flag raised.
• geo_diversity crx JS hosts span NL and RU — includes Russian-hosted infrastructure for a VPN proxy.

Permissions Breakdown
