Ultraviolet Proxy 【LIMITED】

Write-Up: Ultraviolet Proxy

Ultraviolet Proxy vs. Light Speed vs. Other Proxies

The proxy landscape is crowded. Here is how Ultraviolet stacks up against its cousins:

  • Holy Unblocker: Good for Discord, but uses older rewriting techniques. Ultraviolet is faster.
  • Rhodium: Lightweight but breaks modern React websites. UV handles SPAs (Single Page Applications) better.
  • Stomp: Simple HTTP proxy; no WebSocket support. Ultraviolet is superior for streaming.

7. Conclusion

Ultraviolet is a powerful tool for circumventing web censorship, leveraging modern web technologies to remain stealthy and functional. While not bulletproof against determined network filters, it represents the current state-of-the-art in client-side proxy design. Use responsibly and only on networks where you have explicit permission.

3. Features

| Feature | Description | |-----------------------|-----------------------------------------------------------------------------| | Bare server support | Works with lightweight backend servers (e.g., bare-server-node) for scalability. | | No installation required | Runs entirely in a modern browser after the proxy URL is accessed. | | TLS/HTTPS support | Can proxy HTTPS sites without certificate errors (rewrites encrypted traffic). | | Customizable UI | Many deployments include a clean landing page with a URL bar. | | Tabbed browsing | Some implementations support multiple tabs within the proxy interface. | | Cookie persistence | Maintains logins and sessions across proxied sites. |

Legal and Ethical Considerations

The legality of using an Ultraviolet Proxy depends entirely on jurisdiction and intent.

  • In the US and EU: Using a proxy to bypass geoblocking (e.g., watching iPlayer in New York) is a violation of terms of service, not criminal law. However, using one to bypass corporate security policies can be grounds for termination.
  • In Restricted Regimes (China, Russia, Iran): Operating or using any obfuscation proxy can lead to severe penalties, including fines or imprisonment. The UV proxy's "stealth" feature does not make it legal; it only makes it harder to catch.
  • Corporate Policies: Most employment contracts include an "Acceptable Use Policy" that explicitly forbids tunneling or obfuscation tools. Using a UV proxy at work is grounds for immediate dismissal, even if you are not doing anything malicious.

💡 Tips before you post:

  • Visuals: If you have a screenshot of a modern site (like YouTube or a dashboard) loading perfectly inside the Ultraviolet proxy frame, include it. It proves the point better than text.
  • Links: If you are linking to a GitHub repo (like titaniumnetwork-dev/Ultraviolet), make sure to include it so people can actually try it.
  • Safety Warning: If targeting students, keep it semi-responsible (e.g., "Use for research/breaks, don't do anything that gets your school's IT department called").

Here’s a clear breakdown of the proper features for an ultraviolet proxy (a web proxy designed to bypass internet restrictions, often used in school or workplace environments). Holy Unblocker: Good for Discord, but uses older

1. Core Technical Features

  • HTTP/HTTPS Tunneling – Supports both standard and encrypted traffic, including TLS/SSL.
  • WebSocket & Server-Sent Events – Essential for modern real-time apps (e.g., Discord, chat widgets).
  • URL & Content Rewriting – Dynamically rewrites links, forms, and absolute paths to keep all traffic inside the proxy.
  • Cookie & Session Persistence – Preserves login sessions and user preferences.
  • CORS Bypass – Adds proper headers to circumvent cross-origin restrictions.

Key Techniques

  • URL encoding – Requests are encoded (e.g., base64, xor) to hide the real destination from simple pattern filters.
  • Dynamic script rewriting – JavaScript, CSS, and HTML are parsed to replace absolute URLs with proxy equivalents.
  • WebSocket & XHR support – Allows real-time applications (e.g., Discord web, chat apps) to work through the proxy.
  • Service worker integration – Enables client-side routing and caching for speed and stealth.

B. Corporate Security Research

Red teams use UV proxies to test a company's DPI capabilities. If a security team claims to block all non-business traffic, the red team deploys a UV proxy to see if the firewall can distinguish it from legitimate HR web traffic.
