How to hack ADSL modems ??? (Prank)

Half of the Internet users are using ADSL modems for there internet connections , So many of them are not aware of serious vulnerability which exits in these ADSL modems . Today i will try to explain this Prank in this post .

We will use only one tool for this prank and that is Angry IP Scanner .

Step-1: Go to www.cmyip.com. Once the page is loaded you will find your IP address. Note it down.

Step-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 117.195.231.132, you can set the range something as117.195.231.0 to 117.191.255.255 so that there exists atleast 200-300 IP addresses in the range.

Step-3: Go to Tools->Preferences and select the Ports tab. Under Port selectionenter 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. 

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

 

Step-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.

Just enter the username-password as specified above and hit enter. If you are lucky you should gain access to the router settings page where you can modify any of the router settings. A sample router settings page is shown below.

What can Attacker do with your username and password of ADSL??

By gaining access to your router an attacker can change your ADSL settings , can disconnect you from internet and attacker can play some pranks with your ADSL modems .
