Hack an Ethernet Router(ADSL)

Hack an Ethernet Router(ADSL)

ADSL(Asymmetric Digital Subscriber Line) ethernet routers are used by many people across the world because it is efficient in many ways,But it is also the more vulnerable to the network,The most serious vulnerability which can easily be exploited by an hacker(a beginner also ) is……..

In first every ADSL Ethernet 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 and modify the router settings using a common set of default usernames and passwords. Here is how you can do it.

U need some tools like PORT SCANNER which you can download here

1.You need some ip address (usually called ip range),to do so first know your IP address

2.Suppose your IP is 117.192.198.123, you can set the range something as 117.192.198.0 to 117.192.200.255 so that there exists atleast 200-300 IP addresses in the range.

3.In the Angre ip scanner you should set the port to 80(Go to Tools->Preferences and select the Ports tab. Under Port selection enter 80)

4.Now switch to the Display tab, select the option “Hosts with open ports only” and click on OK.

5.Now click start and wait for few moments till the list is ready for u.

6.Now check the results for which ip address port 80 is open.

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. The settings page can vary from router to router. A sample router settings page is shown below.

If you do not succeed to gain access, select another IP from the list and repeat the step-5. Atleast 1 out of 5 IPs will have a default password and hence you will surely be able to gain access.

What will a hacker will do with this……For the most crazy he can change your password and make it in-useble for u an all so change the settings of your router……..

As a result the target user’s computer will be disconnected from the Internet. In the worst case the attacker can copy the ISP login details from the router to steal the Internet connection or play any kind of prank with the router settings.

So the victim has to reconfigure the router in order to bring it back to action.

PROTECTION:

change your username and password as soon as possiable
