How to Hack an Ethernet ADSL Router

Hack adsl ethernet router

 | 

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. In this post, 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:

Angry IP Scanner

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.

    3. Suppose your IP is 117.192.195.101, you can set the range something as 117.192.194.0 to 117.192.200.255 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. IP Scanner Settings

    I have used Angry IP Scanner v3.0 beta-4. If you are using a different version, you need to Go to Options instead of Tools

  4. Now click on Start. After a few minutes, the IP scanner will show a list of IPs with Port 80 open as shown in the below image:

    5. Angry IP Scanner

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

Router Settings Page Hacked!

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

What can a Hacker do by Gaining Access to the Router Settings?

By gaining access to the router settings, it is possible for an attacker to modify any of the router settings which results in the malfunction of the 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 even hijack the DNS by pointing it at a rouge DNS server. If this happens, the victim will have to reconfigure/reset the router settings in order to bring it back to normal.

The Verdict:

If you are using an ADSL router to connect to the Internet, it is highly recommended that you immediately change your password to prevent any such attacks in the future. Who knows, you may be the next victim of such an attack.

Since the configuration varies from router to router, you need to contact your ISP for details on how to change the password for your model.

  4. MY DOWNLOAD MANAGER AND ANTIVIRUS WARNS ME ABOUT “ANGRY IP SCANNER” THAT ,IT IS POTENTIALLY UNWANTED PROGRAM.ALSO MY ANTIVIRUS NEUTRALISED IT AS VIRUS.

    WHAT CAN I DO NEXT?

    IS IT A VIRUS?

    • @ Muralimohan.A.R

      Angry IP scanner is not a virus. However if you hesitate to use it, you can download any of the other IP scanners. Just try a Google search for “free IP scanners” or “Free port scanners” and you will definitely find an alternative!

    • @ Ashif

      Most ISPs have port binding enabled on their end and hence using the username-password from another line (another phone) will not make you connect to the Internet.

  39. man we know the ip its very easy to findout , but we need user name and password ,,, how we can get that , when password is changed

  40. thanks Srikanth but you dont put full information about this hacking methods

    just a little which not help the majority of us

  42. hello srikanth,
    thanks for the info. Generally, the broadband modems contains linux/mac OS. Those friends who says that they stole passwd and all, I dont think it would work because the MAC address will be different. However, logging into these virtual terminals doesnt suffice the role of a hacker. Hacking is not breaking into a computer or to steal passwds. It is more about how this functions. A few challanges for readers. Even logging into the virtual terminal using public ip how you people can really log into a person’s computer? How you can intrude with a firewall installed in a victim’s computer.

    Secondly, how can you keep yourself in stealth and evade.

    Please remember more knowledge more resposibility. Never harm anyone’s computer. How will you feel if someone does to you… Happy Hacking.

    🙂

  51. hi i am rahul i am using bsnl broadconnection at my home ,but i have my friend bsnl username & password but when i put it on my pc its dont work what should i do i want to use my friend user name & password pls help which tool is use? i really confuse.pls help me.

    • @ rahul

      I think port binding is activated on the ISP end which makes it possible to access the Internet only from your phone line. Request them to remove the port binding; if they do it then you can access your Internet from any other BSNL phone line.

  52. What if the default username and password are different? I would like a tutorial on that 😀

  53. It is great.But how we will find the IP of a remote computer about we know that he has not changed his password of router.e.g a friend etc

  54. @ Srikanth, is there any way to remove port binding? the help would be appreciated.

    • @ yogesh chhabra

      I think you need to give a request for your ISP to remove port binding.

  55. hi srikanth
