How to Hack Wi Fi Using Android

Do you want to test your network security? It used to be that you needed a desktop OS such as Windows or Linux installed on a computer with a specific wireless network card. Now, however, you can also use certain Android devices to scan and crack wireless networks. These tools are available for free as long as your device is compatible. Hacking routers without permission is illegal. These steps are provided to test the security of your own network.

1. Root a compatible device. Not every Android phone or tablet will be able to crack a WPS PIN. The device must have a Broadcom bcm4329 or bcm4330 wireless chipset, and must be rooted. The Cyanogen ROM will provide the best chance of success. Some of the known supported devices include:

•  Nexus 7
•  Galaxy Ace/S1/S2/S3
•  Nexus One
•  Desire HD

Download and install bcmon. This tool enables Monitor Mode on your Broadcom chipset, which is essential for being able to crack the PIN. The bcmon APK file is available for free from the bcmon page on the Google Code website. 

• To install an APK file, you will need to allow installation from unknown sources in your Security menu.

    3.Run bcmon. After installing the APK file, run the app. If prompted, install the firmware and tools. Tap the "Enable Monitor Mode" option. If the app crashes, open it and try again. If it fails for a third time, your device is most likely not supported. 

• Your device must be rooted in order to run bcmon.

4. Download and install Reaver. Reaver is a program developed to crack the WPS PIN in order to retrieve the WPA2 passphrase. The Reaver APK can be downloaded from the developers' thread on the XDA-developers forums.

5. Launch Reaver. Tap the Reaver for Android icon in your App drawer. After confirming that you are not using it for illegal purposes, Reaver will scan for available access points. Tap the access point you want to crack to continue. 

• You may need to verify Monitor Mode before proceeding. If this is the case, bcmon will open again.

• The access point you select must accept WPS authentication. Not all routers support this.

6. Verify your settings. In most cases you can leave the settings that appear at their default. Make sure that the "Automatic advanced settings" box is checked.

7. Start the cracking process. Tap the "Start attack" button at the bottom of the Reaver Settings menu. The monitor will open and you will see the results of the ongoing crack displayed. 

• Cracking WPS can take anywhere from 2-10+ hours to complete, and it is not always successful.

How to Hack Wireless Router Passwords & Networks Using Hydra

Today i am going to post how to hack wifi using hydra password cracker by the requesting on our user Leaving your wireless router at its default settings is a bad idea. The sad thing is, most people still do it. Once they've penetrated your network, hackers will change your router settings so they'll have an easy way back in. This allows them to change your network into a shell or proxy so they can forward their traffic anonymously through you when committing other dirty deeds.

If you keep your wireless router at the defaults, then hackers can control your firewalls, what ports are forwarded, and more.

But never mind the hackers, what about your kids?

In this Null Byte, we're going to take a hack at our own wireless routers to see just how secure they really are. We'll be using Arch Linux and THC Hydra, a brute-forcing tool. Windows users, you can follow along if you use Cygwin.

Step 1 Download & Install Hydra
First we need to go to the Hydra website, download Hyrda, and get everything configured. In this article, a "cmd" refers to a command that has to be entered into a terminal emulator.

Download Hydra from THC's website.

Tips for WiFi security

Every technological platform is evolving with time, with portability and security emerging as the major areas of concern. This trend has been affirmed with the advent of WiFi networks in recent years. WiFi networks have become so prevalent nowadays that be it may be any locality, either urban or suburban, you are bound to find one or more networks. Hence WiFi security has become a very important issue nowadays.

WiFi networks offer portability, which is a very essential factor in various circumstances, some of them would be like the following:-

·        With WiFi tethering integrated in most smartphones, one can share their internet connection with another authorized user by creating a new WiFi network and allowing the user to connect and use the WiFi network.

·        Files can be transferred over an Adhoc (Temporary) WiFi network.

·         Communicate over a WiFi network through messages

·        Using  a WiFi network to propagate an internet connection across a particular area

WiFi networks offer a lot of convenience to its users, and are really easy to set up, but they are not without their drawbacks. I shall proceed to explain a major security concern of WiFi networks by an example. For a WiFi network setup at home, the range of the WiFi network extends well beyond the premises. So all an attacker needs to do is to bring his or her device in range of the WiFi network, run a software and voila!!! Within a few minutes the password of the WiFi network is known to that person. Hence our WiFi network, and consequently our personal network, in case of multiple systems running on the WiFi network, are prone to compromise.

So it is important to implement WiFi security in our networks. Wouldn’t it be a nuisance if someone else accessed your WiFi and logged on to the internet without your knowledge?! Fortunately, WiFi security requires just a few basic steps, and preferably should be employed at the time of setting up the WiFi network.

    1.    Set the WiFi security type to WPA2-PSK and encryption to AES

Quite a few WiFi networks run on WEP, which can be hacked pretty easily using basic tools. WPA2-PSK is till date the hardest to crack, and should be used on all WiFi networks. This can be configured at the WiFi access point. A standard procedure is hard to define as the device may differ as per the user.

    2.    WPS function should be switch off

Many WiFi access points have this feature switched on by default. This should be turned off as it is another very common compromise point in WiFi security.

    3.    Set a very strong password

As with all security procedures, setting a strong password goes a long way towards implementing WiFi security. A good password policy would include atleast 10 characters, with numbers, digits and special characters. This would make the password harder to guess, and thus would be the most important way to secure for WiFi security.

Please note that these parameters can be configured only at the WiFi access point, and the process for the same would depend on the person’s WiFi device. In other words, WiFi security would depend on the user's scenario. Ensuring that these three factors are met would make your WiFi network a lot more secure than before.

How to Hack an Ethernet ADSL Router

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 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.
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 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 theDisplay 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 as shown in the below image:
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 defaultusername-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. 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 mode
