How to Detect a Web Proxy

How to Detect Web ProxyUsing a web proxy (Anonymous IP) is the simplest and easiest way to conceal the real IP address of an Internet user and maintain the online privacy. However, proxies are more widely used by online fraudsters to hide their actual geolocation such as a city/country through a spoofed IP address.

As the fraudsters are now becoming more sophisticated in bypassing the geolocation controls by using a proxy server, it has become very much necessary to come up with a means for detecting web proxies, so that the authenticity of the users can be verified. Following are some of the examples where the fraudsters use a web proxy to hide their actual IP address:

  • Credit Card Frauds

    For example, say a Nigerian fraudster tries to purchase goods online with a stolen credit card for which the billing address is associated with New York. Most credit card merchants use geolocation to block orders from countries like Nigeria and other high risk countries.

    So, in order to bypass this restriction, the credit card fraudster uses a proxy to spoof his IP address so that, it appears to have come from New York. The IP address location appears to be a legitimate one as it belongs to the the same city as that of the billing address. In this case, a proxy check would be needed to flag this order.

  • Bypass Website Country Restrictions

    Some website services are restricted to users form only a selected list of countries. For example, a paid survey may be restricted only to countries like United States and Canada. So, a user from say China may use a proxy so as to make his IP appear to have come from United States so that he/she can earn from participating in the paid survey.

Proxy Detection Services:

In order to stop such online frauds, Proxy Detection has become a critical component. Today, most of the companies, credit card merchants and websites that deal with e-commerce transactions make use of Proxy Detection Services like MaxMind and FraudLabs to detect the usage of proxy or spoofed IP from users participating online.

Proxy Detection web services allow instant detection of anonymous IP addresses. Even though the use of proxy address by users is not a direct indication of fraudulent behaviour, it can often indicate the intention of the user to hide his or her real IP. In fact, some of the most used ISPs like AOL and MSN are forms of proxies and are used by both good and bad consumers.

How Proxy Detection Works?

Proxy detection services often rely on IP addresses to determine whether or not the IP is a proxy. Merchants can obtain the IP address of the users from the HTTP header on the order that comes into their website. This IP address is sent to the proxy detecting service in real time to confirm its authenticity.

The proxy detection services on the other hand compare this IP against a known list of flagged IPs that belong to proxy services. If the IP is not on the list then it is authenticated and the confirmation is sent back to the merchant. Otherwise it is reported to be a suspected proxy. These proxy detection services work continuously to grab a list or range of IPs that are commonly used for proxy services. With this, it would be possible to tell whether or not a given IP address is a proxy or spoofed IP.

How to Check whether a given IP is Real or a Proxy?

There are a few free sites that help you determine whether or not a given IP is hiding behind a proxy. You can use free services like WhatisMyIPAddress to detect IP addresses that are hiding behind a proxy. Just enter the suspected IP in the field and click on “Lookup IP Address” button to check the IP address. If it is a suspected proxy then you will see the results something as follows.

Detect Anonymous Proxy

So for all those who think that they can escape by using a web proxy, this post is the answer. I hope this information helps. Pass your comments :)

    Srikanth,

    I tried your “How to Send Anonymous Emails – A New Working Way” technique but when i put url as suggested by you then it give me 500 Internet Server Error…

    Internal Server Error

    The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, no-reply@x10hosting.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

    Give the solution for this …..

      It is possible to trace the real Ip, but needs deeper investigation. Nothing is impossible though!

      @ A. Anjani

      Just goto command prompt and type nslookup yahoo.com to find out the IP of yahoo.com. So use “nslookup” command to find out the IP of any domain (website).

    Hello!

    So if I use a proxy (like “smarthide” for example) a website can still track my real IP address? It’s easy to be traced by your real IP address even if you use a proxy?

    Thanks in advance for the answer!


    • Srikanth
      April 4, 2013 at 3:03 PM

      Using a proxy can hide your identity by masking your real IP address and thus in most cases, forms an effective solution to protect the privacy. However, in extreme cases such as an online crime, it is still possible to trace back (or at least detect the usage of proxy). So, the above article gives information on how web proxies can be detected.

    Great Article…But one question still bothers me…

    How can we completely or perfectly remain anonymous online without using any paid VPN…or its not possible??
