Hacking or Getting Around Proxy Servers At work?

SLAG · 09:17 PM

this is in theory

Proxy server called "Blue Coat" - www.bluecoat.com -

How would I go about getting around it?

Now it seems just like an HTTP proxy as i can still run CMD and do an ftp command from the console. Email Ports are working and functional.

How to get around the "Blue Coat"

you're not gonna get around it.

Most organizations block general internet access at the firewall, allowing HTTP connections only from the proxy servers.

There HAS to be a way to hack it, i am already in the network now i just need to get out there is no such thing as 100% secure

Try one of these in front of the site you want to go to:

Do you have local admin rights on the computer?

Local admin rights on the computer won't help.

Their strategy is likely 2-tiered.

1) They configure your browser to use a proxy server.

This is pretty easy to get around if they did it manually. You can just change it. It's a little harder to get around if they do it via group policies, especially if you're not local admin on the machine.

2) They configure the firewall to block all HTTP traffic not coming from the proxy server.

This one is extremely hard to get around. The only way that I know of to do it right now is to have your machine spoof the IP address of the proxy server. Even then, most firewalls can detect and block IP spoofing.

try this link and let me know what happens

You'll probably get fired if they catch you surfing the net after you hack the proxy server.

How to install the Circumventor program, which gets around all Web-blocking software
Bennett Haselton, last modified 6/13/2004

This page describes how to install the "Circumventor" program, which can be used to get around all Web blocking programs.

However, Please Note!! You don't actually install the Circumventor on the computer that is blocked from accessing Web sites. You, or a friend of yours, has to install the Circumventor on some other machine which is not censored.

For example, if you want to get around Web blocking at work, don't install the Circumventor on your work computer. Install the Circumventor on your home computer. When the installer is done, it will give you the URL for your new Circumventor, and then you write that URL down and take it in with you to work, where you can use that URL to bypass the Web blocking there. Similarly, if you're in China and blocked from accessing certain sites, don't install the Circumventor on a machine in China; instead, get a friend to install it outside China, and then they can send you the URL that you can use to access banned sites.

If you want to, please enter your email address below if you would like to receive updates about the Circumventor software. This will include announcements about new versions and improvements. We will never share your email address with any third party.

Enter your email address:

How to install the Circumventor
The machine where you install the Circumventor must have a fast Internet connection (not dial-up), and it must be running Windows XP or 2000 (this includes most computers these days). Also, once you install the Circumventor on your machine, the Circumventor will only work as long as you have your machine turned on and connected to the Internet, so you should only install it on machines that are online more or less all the time.

To install:

Download ActivePerl from this link and install it. It must be installed to C:\Perl (this should be the default). Accept all of the default options.
Download OpenSA 2.0.2 beta from this link and install it. Accept all of the default options. (If you get to a screen titled "Server Information" and it doesn't have values filled in for "Network Domain", "Server Name" and "Administrator's Email Address", just fill in these boxes with made-up random values -- the Circumventor doesn't use them.)
Download the circumventor-setup.exe program from this link and pick "Save" -- then once you have saved it on your computer, run the circumventor-setup.exe file that you saved.

If the circumventor-setup.exe program succeeds, it will display an "It's ready!" page at the end of the install. If it fails, it will create a file circumventor-setup-log.txt -- send that file to bennett@peacefire.org and we will try to figure out what went wrong.

Happy surfing!

All in all I think your best bet is at home do some research on google. something like the above should work for you.

If you happen to have WindowsXP Pro on your home computer, you might be able to set up Remote Desktop on it and then just surf the internet through remote access from work. It's worked for me. Hypothetically.

htismaqe · 04-26-2006, 02:40 PM

None of this will work, I can assure you.

Most firewall admins block RDP protocol, which means remote desktop won't work.
