Hacking ADSL .. :(

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 theDefault 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.

Almost 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 which can easily be exploited even by a noob hacker just like you. In this post I will show you how to exploit a common vulnerability that lies in most ADSL routers so as to gain complete access to the router settings and ISP login details.

Before you proceed, you need the following tool in the process:-

Angry IP Scanner

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

Step-1: Go to www.whatismyipaddress.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 117.192.195.101, you can set the range something as117.192.194.0 to 117.192.200.255 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.

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

 

Step-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.

 

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. 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 can an Attacker 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 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.

 

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.

Its Over... :)

Its over.. :)

dated 25th july 2011

yesterday was not so great and not it was today, but with the new rays of sun lets hope  tomorrow will be a better day, 


frankly speaking guys writing your thoughts somewhere helps you to be focused and it also helps you to know yourself better, 


i must say if you have a high blood pressure problem then you should try it. write your thoughts somewhere or just write down what you had done today.
because when you write your thoughts somewhere and then you read it, it just clears your doubts if you have any and it also helps you to take some decision on the basis of your thoughts, or if you have some goals then you should also write them and on everyday basis you should check yourself what you had achieved or what you were tomorrow and what were you now..

i know what are you thinking guys, the heading doesnt meet the content :) ..
the beigning lines of this post were just ment to gave you a message that i had experienced form my self so i had shared it with you all..

now the big question ?? what is "over".. :(
hmm..
1.Belief..
2.The track..
3.The way i used to take this life..
4.Always complaining Attitude..
5.The Way i lie with myself..

now as the U.P.T.U always says elaborate :)
1.Belief..
yes never believe that god will gave you what all you want, if you dnt even gave it a try, lets take an example,
Hen gave eggs, now what she do is, she sit upon them warm them and wait till her young one comes out from the shells.
now bring one Hen that have a blind hope on God, she gave eggs then she left those egg at that palce, she didn't sit on them cause i said she believe on god :)
now you all know the result..yeh the chicks came out from those eggs yeh dude dnt have that dream in your mind cause you all know the truth, they will not hatched from there without an effort.
so just dig that belief, and let me remind you one oldy proverb that we all had readed in our moral science book "God help those who help themselves".
:)

2.The Track..
yes the way you choose to solve your problems, some says do it smart way some says hard way, and what i say is there is no smart way without hard way" :)
so work hard and and i promise you that you will get a smart way at the end.

3.The way i used to take this life..
Never have that feeling with your self that you have someone with you, because its a truth no one will always be with you, always take responsibilities for your own, always be dependent on yourself, if you will always be responsible for yourself then dude no one can stop you from achieving what you really wanna be.

4.Always complaining Attitude..
Never complain from others rather then complain with yourself, it will help you to know your mistake better, and also moods of others and you know what you will never let any body know your weaknesses.

5.The Way i lie with myself..
Never do that it will never help you, rather have a view, why this fake dream will not turn into reality, now this view will help you in identifying your weak points about your dreams..and if you know its failure before then you can, and you will turn them in reality someday. :)
