How do you bypass school/corporate internate filters
 

After reading the dig article "Kids Outsmart Web Filters" which links to a CNet News Article. I was wondering what measures you have used or know that have been used to bypass internet filters. I have the sole interest of securing internet access in my schools.
Thanks guys!

Ever heard of anonymous proxies?

Re: How do you bypass school/corporate internate filters
 

I've heard of lots of different ways. Proxies being the easiest and most prevelent way to do it. But it is simple to ban all proxies from being accessed. I read through all of the replys to the dig article and there are lots of ingenous responses, but i was wondering if there were any others that daniweb's people know about that not many others do.

Re: How do you bypass school/corporate internate filters
 

Doesn't matter if they ban proxies. Chances are they already have. If you access it via a secure connection then there's nothing they can do about it.

www.proxify.com will be blocked by the filter, but if you type:

https://proxify.com then it will work perfectly.

When I was in the army, they had filters. The problem I had wasn't that I wanted to look at porn or anything silly, but that even legit e-mail sites were locked out. Being a programmer, with access to a linux box that was outside of the network, I wrote a perl script that allowed me to type in the URL, and it used the LWP module to retrieve the HTML, added a base tag to the HTML (to expand all relative paths) and modified the links so that it referenced my perl program, so that it could get the HTML for the HREF'd page, and saved the HTML file on to the server (the linux box running perl, which was also a web-server). I suppose the concept is a proxy, but when someone can program, you have just lost over half of your power to lock them out of things.

hehe...in my school the internet security was simple (that was long time ago, like 5 years). We were not allowed to use forums, look at porn, write email, and go to controversial websites, and play games. Security? Two old ladies ran around the computer lab looking over everybody's shoulder trying to see if they were doing anything wrong. Given their illiteracy, I was caught and warned many times for programming in C++, and VB (they did not even know what it was, but if they dont know, its illegal). Having a DOS window (to run some program), got me yelled at many times. Ahh...the good old days.

I save all my flash games to my account's document folder.

Re: How do you bypass school/corporate internate filters
 

yep proxies thats how we do it. We set up a php proxy and someone hosted it. Are school blocked stuff randomly like CNN. Then they made it so you couldn't change the proxy but we went into the registry and edited the actual value or ran live linux and changed the proxy in there. You can also use firefox.

Watch out at my school people get banned for that usb flash drives are better. We ran Quake III off of a cd. We took the installed files and copyed em to a cd

for IE go to tools->internet options->connections->lan settings-> x the box to use a proxy and enter the ip for that proxy and port prob. 8080 or 80 for http

Re: How do you bypass school/corporate internate filters
 

Ehhh. I, an 8th grader, used www.proxify.com and www.surfatwork.com

But that got blocked. So now we go into the cmd and type ping www.myspace.com and insert the ip address into the address bar. So this gets past all of our blocks. O yea I need to try server crash's way. I loved usuing proxify.

Re: How do you bypass school/corporate internate filters
 

You can also set proxy options in the tools/option menu to some ip address that allows it. That way you don't have to constantly go through proxify. There is also a way to edit the URL to include a specific port number or something, but I don't remember how to do it.

Re: How do you bypass school/corporate internate filters
 

Your way didn't work for proxify.

Re: How do you bypass school/corporate internate filters
 

they blocked the use of proxies and our school. Basically any unkownd ip address is blocked and they block all but non essential ports. I don't really use proxies at school becasue the main thing I used them for was games but now that we run live versions of quake off of cds I don't care.

Re: How do you bypass school/corporate internate filters
 

Yea I tried to change the proxy by going into lan setting and putting in a proxy, but it didn't work. Our Computer Specialist is really cool and he teaches us a lot about computers and he told me that our school(s) in our city disable the changing of the proxy. But he said I could use one in there. He mentioned something about the web interface I need to ask him more, but does anyone know how i could do this? He said that there we are bunch of them. He wants to see if I can figure it out.

Re: How do you bypass school/corporate internate filters
 

I acually set up my own cgi proxy on my computer and am using it.

If you allow traffic out on TCP 443, here's one way of bypassing your proxy. I've been doing this for awhile now. Of course, it's just a matter of finding out which ports are blocked from the inside and finding one that's open in the event 443 is closed, but you get the idea.

I could also do ARP spoofing, IP spoofing, or a number of different things to get around it, depending on how you've implemented it.

Re: How do you bypass school/corporate internate filters
 

Well I'm sure ya all kno how to bypass the Google Images filter and such without using a proxy.

1) Google.de

2) Now, go to advanced settings, and set the main language back to english

3) search pictures away :)

Then again, our WebSense filter's pretty lax anyways...

Re: How do you bypass school/corporate internate filters
 

I think that is pretty sad that schools block google images. They did at our school too. They blocked the homepage of wikipedia once! It is pretty sad, but I guess you have to block the retarded kids from looking at pron at school. The school also gets money from the government if they put filters in.

Re: How do you bypass school/corporate internate filters
 

They dont get money for filtering it, they are protecting their asses by doing it. If a parent decides to sue a school becasue their child looked at porn there, they would win. This is why filters are used. Its just to protect them from lawsuits.

Re: How do you bypass school/corporate internate filters
 

Yes, true.

Roger that nizzy.

Re: How do you bypass school/corporate internate filters
 

Hmmm, actually I thought they got some E-rate funding or something to help pay for internet and computers, but maybe I am wrong.

Re: How do you bypass school/corporate internate filters
 

Actually only some school districts can get government funding for technology. Most, have to supply most of it on their own from towns taxes.

Re: How do you bypass school/corporate internate filters
 

I see. Thanks for clearing that up.

Re: How do you bypass school/corporate internate filters
 

i had a nice system hardware lockout's that you cannot change anything proxy's and software firewalls and content protection systems download restritions checkpoint firewalls you think of it we had it and i got arround it! using these steps!

1.Got a CGI proxy that was using SSL which the content filter didn't see as well as the download filter!
2.Downloaded portable firefox now i had the web unlocked for me!
3.i was a restriced user and there were no cd drives and floppy's were locked!
4.i broke the SAM for the ADMIN by grabbing it and the syskey in the repair DIR!
5. It took a while even with ranbow tables but i cracked it!
that was level one
Now i hacked into the webserver's password! and from there it's another very long story but in short i got the sql records for all the accounts.......... and found the admin...... and broke free!

Re: How do you bypass school/corporate internate filters
 

I guess we won't be hearing from you in a while. I hope you like the pen.

Re: How do you bypass school/corporate internate filters
 

Oh, as for students like us. Who are not so well versed with technologies. We usually get the IP address of the website and paste it into the browser to surf. It works almost all the time.

Web URLs and their names don't change. IP might change although rare. So proxies block the names rather than their IPs!

Re: How do you bypass school/corporate internate filters
 

right, but aren't the hyperlinks jacked? Like if the link references the same domain, but a different page?

Re: How do you bypass school/corporate internate filters
 

I think they are sometimes, but it depends on the filters.

Re: How do you bypass school/corporate internate filters
 

They did that at our college. As they only block the proxy changing on IE, we downloaded portable firefox (download here), and could then change the proxy settings through that. (And browsing with firefox is so much nicer ;) ) This an be run from your user space, or from a USB drive.

Remember - The simplist method is often the easiest.

Re: How do you bypass school/corporate internate filters
 

Yea I already figured out that way and many more ways of doing it. Plus school is out and I am going to a new school next year in a different city. YEAY I can figure out different ways to bypass it!

Re: How do you bypass school/corporate internate filters
 

hehe just remember to be careful in what you do. We had someone who very luckily escaped a jail sentence from our college due to hacking past the network ;)

Re: How do you bypass school/corporate internate filters
 

Ya but that is college. I am only in Middle School. I don't think I could get into that much trouble and plus I am not an adult yet. We aren't really doing anything that illegal. Just trying to look at wikipedia because the homepage is blocked.

Re: How do you bypass school/corporate internate filters
 

Its still against the computer misuse act, and could also breach on the data protection act as well which makes it illegal.

And also, even if your not an adult yet, anything you do at your age could stop you getting a job when your older, among many other things.

But hey, im not here to judge.. just to point out the facts. :)

Re: How do you bypass school/corporate internate filters
 

Well actually they erase your record as a juvenile and it doesn't show up as an adult, so no it wouldn't prevent me from getting a job. But you must be careful when you are doing it.

Re: How do you bypass school/corporate internate filters
 

I cant believe no one has said to connect to a remote linux box through xserver and view websites from there.

xserver ports are blocked you say? change the config on your linux server to run xserver on port 80 :-).

Even the admins asked me how i did this, so they could check on their email from home.

EVEN BETTER: turn ssh tunneling on your xserver and now not only have you got out of the proxy problem, but they cant read ANY of the tcp/ip or udp traffic you send to that server because its all encrypted.

Re: How do you bypass school/corporate internate filters
 

what we did for google images was simple, search for lets say jennifer aniston, wait for the results, then click images, that got us passed ranger from sentinel software. :cheesy:

Re: How do you bypass school/corporate internate filters
 

geeze you guys all went to strict schools, it guys knew i was hacking the network (after they relised i had more network rights than the admins) didnt get a detention let alone banned from computers lmao

Re: How do you bypass school/corporate internate filters
 

I go to a public school and i don't think this quote works well.
It seems that our computer technicians already bypassed that fact. tried to do something similar to that but however, it was a waste of time. Our computer technician seems to be a very smart guy. I think he even has a log that keeps tracks of what each user does. But i don't know for sure. the guys is quite the smart one to figure out this stuff as well.

Also another thing to add, he has blocked "non-administrator" users from accessing C: and many menus from the computer. Therefore reg edit is out of the question. Can't change the internet options and can't access command prompt to ping my way in.

Also another thing to add, can't download files from school, it is also blocked. This computer technician is very smart in regards to computer security
