In the current world many companies, offices as well as educational institutes use to block some social networking sites like Facebook, Orkut etc. and also file hosting sites in order to avoid any distraction of its employees. But you know, despite this some people are still willing to access these sites. The best and simple way to do that is of course to use some proxy servers like Ultrasurf etc. that lets you surf those blocked sites secretly. But have you ever thought, is it safe to use password to login various accounts using these proxy servers?
Read below to get insight of on this security issue.
What is the threat actually?
In order to find the answer of this question first you need to know the concept of working and what happens in back-end while you use proxy servers. A proxy server receives a request from user for an Internet service (such as a Web page request). The proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.
If you just want to browse the web without entering passwords and watching YouTube videos, you have no threat and there is nothing to worry about. But as soon as you want to access your accounts which are password protected these proxy servers can very easily monitor your activities and steal your private data like your password and other personal informations. So it is always risky when you are using these free proxy servers for accessing password protected accounts specially banking and other financial information like credit card numbers etc.
