Green Tunnel

What is Green Tunnel?

GreenTunnel is a powerful tool designed to bypass Deep Packet Inspection (DPI) systems employed by many Internet Service Providers (ISPs) to restrict access to certain websites. These DPI systems often rely on techniques like DNS spoofing and SNI (Server Name Indication) monitoring to identify and block targeted content

Highlights

• Bypasses DNS-based censorship by using DNS over HTTPS and DNS over TLS to obtain the correct IP addresses
• Circumvents HTTP-based blocking by strategically splitting HTTP requests into multiple TCP segments, preventing the DPI system from identifying the blocked content
• Defeats HTTPS-based filtering by fragmenting the initial TLS handshake (CLIENT-HELLO packet) to conceal the SNI information, which is typically used to identify and block specific hostnames
