One way to protect your self-evident when surfing the World Wide Web is with a secure proxy server. But just choosing any proxy to use is not advisable, as you may pick one which is not secure and rather than your browsing being anonymous your information could just be sent somewhere else, which may make this a terrible situation for you. More and more the world and especially the internet are filled with individuals that are waiting to steal your identity. These internet pirates are not just a single individual, but they are an entire huge team which has a great deal of resources and they realize the enormous gains which may be gotten, with very limited risks of getting caught for digital fraud and theft.
One of the fundamental and most important issues when surfing the internet is that most information is moved in easily readable format, known as ascidia text. So essentially all information that renders your computer and travels across the net can be immediately intercepted and read by anyone who chooses to do so. One place that all online information is intercepted is the ISP, who logs everything everybody does online, together with a number of other places. So to maintain what you do online personal many people would use a free proxy server list. What this means to you as a user of the world wide web is these internet pirates may either purchase, lease or even hack into a server and then put in their own proxy server and then set them on the world wide web, advertising them as free proxy servers to the general public to use.
Each and every day thousands of people use these proxies and unknowing to them all their information has been intercepted and read. With a server configured to cache mode and allowing software these online pirates can capture everything your usernames, account logins and passwords, your credit card information, social security number, you name it and they have your data. So they not only offer you what you believe will protect you, but they are providing themselves with a means to steal all of your information in the title of anonymity
The answer here is fairly simple, it is one of 2 reasons 1 being that someone, more than likely a business did not close all the ports to their proxy server or 2 it has been done by someone on purpose to make a snare to steal peoples information. You want to be extremely careful when choosing to use a protected Proxy server and it is from a respectable firm that runs a secure expert server. Not a free service which may well be conducted by a group of Eastern European hackers, with just one motive in mind.
