Website banned ? Try the encrypted url

There are many ways to ban a website from a network. You can ban its domain name, the IP address where it is hosted, or through a keyword check might check the content in real time and decide not to display it. This makes it extremely hard to show how to bypass the ban and access the website that you want to access. It is however still usual to only ban the domain name - the url - of a website which leaves us some outs to access it without using proxies and the like.

There are actually several ways to replace a url with a encrypted one. The result in the end will be the same but it might be possible to bypass the ban using the encrypted url. A fine tool that displays all variants of encrypted urls is url encryptor. Just enter a url that you want to visit and it displays all encrypted forms (and others) on its page. You can then try and access the website that is banned using those urls and you will be surprised how often this actually works.

I think an example would be fine. Let us take myspace.com for example. If myspace is banned you could use the following urls to access it anyway:

  • Base64 (works in Firefox and Opera)
  • Hex (works in IE and Opera)
  • IP (works in Firefox, IE and Opera)
  • Dword (works in Firefox, IE and Opera)
  • Octal (works in Firefox, IE and Opera)
  • HexDec (works in Firefox and IE)
  • Mixed 1 (works in Firefox and IE)
  • Mixed 2 (works in IE and Opera)

Another method that could work would be to access http://myspace.com/ instead of http://www.myspace.com/

This wont work for any company that does website filtering correctly. For places like Myspace, almost every url on the site looks like: http://www.myspace.com/Content Where I work, we block anything that “Myspace” in the url. This means that you might be able to get to the login page but when it goes to the next page it will be blocked.

The most any of these will do will let you get to the home page. Not any pages below them unless they use absolute url’s in their site/

How about this then.. http://0xd8b22674/secretshowsde

It takes some time but you can simply replace myspace.com everytime by copying & pasting the links and every site will load.

My school is using this new blocking system that is able to block websites by category so since all proxy sites are placed in the security.proxy category they are ALL banned, I have a list of over 700 proxys and they are all banned, can someone tell me a way around it? the sites I try to get to are blocked wether use IP or even if I encrypt it, they are useing lightspeed systems to block it

try this site. http://www.eoinmcgrath.com. see if works for the school. try to use encryting in the proxy website.
could you let me know if it works for that system

anonymous person says, July 2nd, 2007   

to kugyo, you can allso try a proxy that is a secure site (it will have https:// instead of http:// in the url, 1 in example is {https://www.kproxy.com/} and another that might work is http://www.the-cloak.com/login.html, the-cloak will let you choose https(secure) surfing and other options about java and cookies

brilliant, is there any way to access http://www.youtube.com as it’s banned here. I’ve used some anonymous proxy websites. they accessed the website, but it won’t load the video. at the place of video. it just stops and Loadin, Loadin and Loadin … I’ve waited a lot but it resulted in nothing.

so, can anybody tell me any way through.

farley and norton says, July 11th, 2007   

yea… we have expierience with lightspeed… IT SUX BALLS!!!!!!!!!!!!!!! as soon as you find a proxy… it flippin blocks it….. i understand your pain. i just read about a great idea though… download a proxy program onto a USB flash drive, at home, and run it on the schools computers through the flash drive. or…. download a program that lets you “use” your home comp at school….. it’s like a window…. but so much better. gotomypc.com has one…. not sure if it’s free though….. but it will have info on the name of that type of program….

I would have never thought of this. That’s a great trick. Of course there’s about a quadrillion web proxies, but I’ve found most of them to be fairly buggy. Many also don’t support POST data, etc.

Arcan3 says, January 18th, 2008   

None work for me… for some reason firefox gives me a Connection timeouts on alsmost all of them except those that are forbidden

HI! My school blocked all proxies and any other website that is not “educational”, I tried the encryppted URL but it won’t let me get to another page even if i tried to change the next url shown. ANY other website that doesnt use proxies i could use?! I need to check my yahoo email and myspace and facebook!!! Grrrr! THANKS TO ANYONE WHO CAN HELP.
(note: can not use proxies or anonymizers)

If the browser decrypt the domain name before sending the dns query it could not work.

So why is it browser dependent if the encrypted domain name is sent as is to the dns ?

Just asking myself if someone could write or modify a local dns forwarder to encrypt domain names sent to real nameservers.

Hm. It doesn’t work.

the filter my school uses (fortiguard) is really good. It blocks proxy sites and when i tried to encrypt the url it blocked it anyway. it even blocks anything with the word Naruto in it.

I’ve used some proxy servers before (like vvd1.net) but that got blocked too. Though I have found this one page about the filtering system, and it says it “caches” things…

-sigh- If anyone’s got a solution I’d love to hear from you. (proxy me plz at hotmail dot com)
