| Factor | Detail | |--------|--------| | | VPNBook claims “no logs,” but free VPNs lack third-party audits. | | Encryption | Uses AES-256-CBC + SHA512, which is strong. | | Authentication | Shared username/password (rotated every few hours). Weak — no per-user identity. | | Malware risk | ZIP files from free VPN sites could be tampered with. Always verify hashes. | | Traffic monitoring | Free VPNs may inject ads or sell aggregated data. | | Server location spoofing | Some servers may be honeypots or compromised. |
