Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Toplenka Net — Томлёный VPN-прокси [browser-hijack] + malext.io malicious_extension_sentry (+2.5, capped).
• proxy permission gives full control to reroute all browser traffic through attacker-controlled servers
• Privacy policy is Google's generic policy — not scoped to this extension; admits data collection and 3rd-party sharing
• Developer is anonymous (no name, free Gmail, no verified publisher) with only 4 installs
• install_url_hijack: extension opens an external URL on install (t.me contact likely)

Evidence

• proxy_permission manifest proxy declared — can redirect all browser traffic to any SOCKS5 server operated by developer
• generic_privacy_policy store PP URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0
• free_webmail_dev_no_name store Developer email vale99505@gmail.com, no developer name, not verified publisher → reputation elevated
• install_url_hijack manifest install_url_hijack=true, external host t.me in js_external_hosts; opens 3rd-party on install
• install_perm_anomaly api Only 4 installs with HIGH-tier proxy permission: small_install_high_perm=true
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit policy declared
• no_code_findings crx code_findings_raw empty, obfuscation_score=0.0; 5 JS files scanned with no detected signals
• no_cve_findings crx cve_findings_raw empty; no known vulnerable libraries detected
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Toplenka Net — Томлёный VPN-прокси [browser-hijack] + malext.io malicious_extension_sentry; score 5.78 -> 8.28 (+2.5 cap 2.5).
