DarkFlare : Bypassing Censorship With TCP-Over-CDN Technology

A stealthy command line tool to create TCP-over-CDN(http) tunnels that keep your connections cozy and comfortable. Now with public test relay servers!

What Is This Sorcery?

DarkFlare is a clever little tool that disguises your TCP traffic as innocent HTTPS requests, letting them pass through corporate firewalls like a VIP at a nightclub. It’s like a tunnel, but with more style and less dirt.

It has two parts: a client-side proxy (darkflare-client) that encodes TCP data into HTTPS requests and sends it to a Cloudflare-protected domain, and a server-side proxy (darkflare-server) that decodes the requests and forwards the data to a local service (like SSH on port 22).

It’s protocol-agnostic, secure, and uses Cloudflare’s encrypted infrastructure, making it stealthy and scalable for accessing internal resources or bypassing network restrictions.

When using this remember the traffic over the tunnel is only as secure as the Cloudflare protection. Use your own encryption.

Why CDNs?

Services like Cloudflare, Akamai Technologies, Fastly, and Amazon CloudFront are not only widely accessible but also integral to the global internet infrastructure.

In regions with restrictive networks, alternatives such as CDNetworks in Russia, ArvanCloud in Iran, or ChinaCache in China may serve as viable proxies.

These CDNs support millions of websites across critical sectors, including government and healthcare, making them indispensable.

Blocking them risks significant collateral damage, which inadvertently makes them reliable pathways for bypassing restrictions.

Stop Network Censorship

Internet censorship is a significant issue in many countries, where governments restrict access to information by blocking websites and services.

For instance, China employs the “Great Firewall” to block platforms like Facebook and Twitter, while Iran restricts access to social media and messaging apps.

In Russia, authorities have intensified efforts to control information flow by blocking virtual private networks (VPNs) and other tools that citizens use to bypass censorship.

AP NEWS In such environments, a tool that tunnels TCP traffic over HTTP(S) through a Content Delivery Network (CDN) like Cloudflare can be invaluable.

By disguising restricted traffic as regular web traffic, this method can effectively circumvent censorship measures, granting users access to blocked content and preserving the free flow of information.
