It's September and many students are going back to school. One burning technology question has left students flabbergasted for the past decade. The age old question, "How do I get around my school's web filter?", has been answered in a number of ways. Some out rightly condemn the student for asking the question, and tell him to pay more attention to his school work. This answer troubles me the most because it is entirely contrary to the hacker ethic. The student has asked a question, and therefore deserves to know the right answer. Telling him that the filter cannot be circumvented is censorship.
More noble users have cited web proxies as an easy way to thwart the school's web filter. The proxy acts as a buffer allowing the user to gain access to blocked web pages quickly and easily. This method is preferred because it only requires the typing in of a URL into a browser window. Unfortunately, once the proxy is found by the filtering company it will be blocked and no longer allow access by the user.
Students often feel suppressed and stumped by the elusive filtering technology. This should not be the case, as all good hackers know that the human mind is far more powerful than that of a machine. Therefore, this same mind should be able to break away from the chains of censorship by exploiting technology to his advantage. I will show you how to do this.
Problem: Students use web proxies to gain access to blocked sites. As soon as the filtering company or school administration detects them they become blocked and no longer usable. The student needs a way to get passed the filter.

Google is said to be a hacker's
favorite weapon. It is no different in this case. By using Boolean searches you
can find TONS of new web-based proxies. Googlebot updates its list daily and it
is constantly expanding. Use this search term:
+"include form"
+"remove scripts" +"accept cookies" +"show
images"
This search will look for all
CgiProxy/PhpProxy web sites that have been set to default or have not been
drastically altered. There are thousands of these sites out there on the
Internet, and many new ones that come online each day. The filtering companies
use search terms like these to find new proxy sites and block them. Now the student
can fight fire with fire.
Here is a typical web proxy page:
See why the above search term
worked? It looked for the specific key terms that are on a CgiProxy/PhpProxy
page. By using all of those key words in one long Boolean term, we can
eliminate approximately 20,000 web pages from Google's list and get better
results.
+"Include Form"
+"Remove Scripts" +"Accept Cookies" +"Show
Images" +"Show Referer" +"Rotate13"
+"Base64" +"Strip Meta" +"Strip Title"
+"Session Cookies" +"New Window"
The flaw in using these search terms
is that there may be some duplicate proxy pages.
Testing proved that the proxies higher up on Google's list (pages 1-30) had
fewer broken links than those in the back. Here is a table showing the number
of results given by various search engines using the string above:
The good search engines to find web
proxies on are Google, Yahoo, AltaVista, AllTheWeb,
and MSN. I would not recommend using any of the others.
I am going to switch focus now from
the technical means of circumventing censorship and look into the controversy
surrounding internet filtering in
America
.
Internet
Censorship in the
U.S.
The
United States of America
is supposedly a country that bathes
in democracy and is the decapitator of censorship. Our nation is widely known
for criticizing totalitarian regimes that utilize web censorship as a means for
oppressing their people. Countries like
China
,
North Korea
,
Saudi Arabia
,
Cuba
, and
Iran
are among the worst offenders. It
is cynical to think that the
U.S.
would use internet censorship in
its schools and libraries much in the same way as these dictatorships. The sad
part is that we do.
The Here and Now
Since 2001, the
United States
has required all schools and
libraries that receive federal funding (which is most of them) to install web
filtering software. The Child Internet Protection Act is flawed in that the
blocking software that it requires does a poor job of filtering out illicit
content and instead blocks legitimate web pages. Prominent web sites such as
Amnesty International, the National Organization for Women, various educational
blogs, and even sites that innocently promoting Islam and Buddhism have been
blocked. The blocking of legitimate information in the
United States
is called censorship. There is no
other word for it.
School administrators have left the
responsibility of blocking web pages to companies that seek to turn a profit.
Among them are Websense and N2H2, both of whom have long histories of dislike
from students and teachers across the country. This discontent has arisen
because the filter blocks many quintessential youth and educational sites. The
cyber generation has been hog-tied from learning by corporations, flawed
politics, and media hysteria.
The Future
The situation will only get worse.
On July 26, 2006, by a vote of 410 to 15, the House of Representatives
passed the Deleting Online Predators Act. This bill states that all sites on
the Internet that "allow communication between users" must be blocked
in schools and libraries. The legislation arose after the deaths of several
teenagers that had met strangers on the social networking site Myspace.com.
Critics point out that the majority of stalking is done from a computer within
a child's home, and more often than not the child actually knows the predator.
Despite these warnings, elected officials have bowed to parental hysteria in
hopes of keeping votes for the upcoming election.
This table clearly shows the
ignorance of our legislative branch. Usually there is a severe partisan split
among Republicans and Democrats on almost all issues. They were tricked into
voting for this bill: who does not want to delete online predators? I ask the
question "Who wants to delete the Internet?"
That decision will have a
devastating effect on research and general activities on the Internet. All
blogs that allow comments would need to be blocked in
U.S.
public schools and libraries. The
number of sites that would fit into this broad definition are enormous. If this bill passes the Senate and is signed into law by the
President, the
United States
will officially become a nation of
censorship.
Even if the Deleting Online Predators
Act does pass and the Internet becomes severely restricted, there will always
be those that believe in freedom and will work tirelessly to circumvent
censorship.
