How to block hotspot shield VPN in network with WFilter NG firewall?

Hotspot shield is a popular VPN service, with free version available.  When launched, it will try to connect a lot TLS sites for traffic relaying. If you do packet sniffer with wireshark, you will see  traffic  from famous sites like “google.com, baidu.com…”. But in fact, it’s hotspot vpn traffic in the camouflage of normal TLS.

Anyway, our team has worked out a protocol pattern to block Hotspot shield traffic completely in your network. WFilter identifies Hotspot via signature matching, so no matter in which transfer type or client version, all Hotspot traffic can be blocked.
