How to Hack ADSL Router?

hacking-routers_main

Almostleft half of the Internet users across the globe use ADSL routers/modems to connect to the Internet. However, most of them are unaware of the fact that it has a serious vulnerability in it which can easily be exploited by anyone with a basic knowledge of computer. I will show you how to hack an Ethernet ADSL router by exploiting the common vulnerability that lies in it.

Every router comes with a username and password using which it is possible to gain access to the router settings and configure the device. The vulnerability actually lies in the Default username and password that comes with the factory settings. Usually the routers come preconfigured from the Internet Service provider and hence the users do not bother to change the password later.

This makes it possible for the attackers to gain unauthorized access to the router and modify its settings using a common set of default usernames and passwords. Here is how you can do it. Before you proceed, you need the following tool in the process:

Hacking the ADSL Router:

Here is a detailed information on how to exploit the vulnerability of an ADSL router:

  1. Go to whatismyipaddress.com. Once the page is loaded, you will find your IP address. Note it down.
  2. Open Angry IP Scanner, here you will see an option called IP Range: where you need to enter the range of IP address to scan for.

“Suppose your IP is 192.167.195.101, you can set the range something as 192.167.194.0 to 192.167.200.255 so that there exists at least 200-300 IP addresses in the range.”

3. Go to Tools->Preferences and select the Ports tab. Under Port selection enter 80 (we need to scan for port 80). Now switch to the Display tab, select the option “Hosts with open ports only” and click on OK.

4. Now click on Start. After a few minutes, the IP scanner will show a list of IPs with Port 80 open.

      5. Now copy any of the IP from the list, paste it in your browser’s address bar and hit enter. A window will popup asking for username and password. Since most users do not change the passwords, it should most likely work with the default username and password. For most routers the default username-password pair will be admin-admin or admin-password.
