5 Steps to Secure your home Wireless Network

Posted in Articles, Networking, Security • 7 months ago • Written by Shais • 7 Comments
Almost all houses are equipped with Wireless Network equipment nowadays, but most users are do not know enough about the security of Wireless Network. If we search around a bit carefully we find many Wifi Network with default name. When the SSID (Service Set Identifier) is by default or factory name, maybe the password is also.
So lets see some steps of securing a home Wireless network to protect our network from being hacked by hackers or neighbor kids;).

1. Find a Qualified Wireless Access Point for Wireless Network 

Buying a good branded Wireless Access Point (AP) which support newly strong wireless security protocols with flexible features and try to install and configure it correctly. If you don’t know how to install, configure and secure the WAP, ask  someone expert or read the guide Notes. Be careful, don’t used it by default.

2. Change the Default SSID of Access Point

Change the default name and hide it by turning off SSID broadcasting and connect all wireless devices manually. When a Wireless Network SSID is hidden the wireless access point doesn’t broadcast it’s name around and no one can find and guess it simply. But it’s possible to find with wireless Hacking tools.

3. Enable Security with WPA2 and Strong Password

Enable Security options of  Wireless Access Point with most strong wireless security protocol like WPA2 (Wi-Fi Protected Access II) and set a complex Password. A complex password is contain Number, Symbols, lower case letter and upper case letter.

4. Enable MAC Address Filtering

MAC Filtering (Media Access Controller) prevent unknown devices from being connect to WAP without your permission. You see tow option, Deny and Allow, the deny option will deny the clients specified by any enabled entries in the list to access. Allow option will permit the clients specified by any enabled entries in the list to access the WAP.

Note: You can find MAC address of your connected devices from DHCP section of WAP and get the others from it’s network settings or using soft tools to find them. The easiest way to get MAC address of all devices, first connect them to WAP and then check the DHCP Clients List.

5. Change the Interface default user name and password

Change the factory default user name and password of web-based interface of Wireless Access Point and set different user name and strong password. Each manufacturer Wireless Routers has a simple user name and password like Admin, pass or 12345 to ease access for first time.

Optionally, you can configure DHCP (Dynamic Host Configuration Protocol) to limit the range of IP address from DHCP scope.

Finally you must keep Wireless Access Point in a secure area or in a box and locked to prevent from being reset to factory settings. Don’t forget to check it up sometime and update your knowledge about Information Security.
So it is enough for Securing a SOHO (small office or home) network. If you don’t know the basic Wireless Access point configuration, I recommand you to read the How to Setup My Home Wireless Network? article.

Posted in Articles, Linux, Security • 7 months ago • Written by Shais • 18 Comments
In previews article about securing  or Hack Wireless Network “5 Steps to Secure your home Wireless Network” we understand pretty enough for securing home Wireless Network. But now it’s time to know how the hackers break and get access to your Wireless Access Point WAP?
In this article I’m gonna to Show you 5 ways to pen test a wireless network. It’s all for educational purpose only and don’t use in wrong way.
The Tools we need is Kali Linux or Backtrack. Download the latest Kali Linux from here.
First one is using Wifite to capture Wireless traffic and save it as a file, and next crack the saved Client handshake in the file with aircrack and creating word list with Crunch.
In order to do this, open terminal and type wifite and hit enter.
Wifite Result

Let the Wifite search and find all Wireless SSIDs.
When you find them press Ctrl+C to stop searching and select the number of network you want to hack it.

In the point of WPS Attack, press Ctrl+C to reject the WPS Attack.

Wifite forced the clients to authenticate with WAP by sending de-authenticate request.

Authentication is the process of sending user name and password from client to WAP. When the clients send request, the packet will captured by Wifite. It continue lessening for handshake…

Now it found, captured and saved a handshake packets.

Now try to crack the captured files with Aircrack and Crunch. To do this type the commands like the screenshot and press enter.
Create Wordlist and Cracking

Wile the Crunch create password list and the aircrack check them to find the password.
Cracking Process

It takes time too much just for numbers but be patent, and if you try to crack alphabets it’s possible but need more time and a strong processor.
The Second way: Using airmon-ng to set the wireless card to monitoring mode and airodump-ng for capturing clients handshake. For cracking again you must use aircrack with a password list.

      Hi dear Raza.
      It’s not work if you just copy the Kali image file to a USB flash.
      Create a bootable USB according to this topic “How to Create a Kali Linux Live and Bootable USB?“.
      If you have any question let us know.
      Good luck.

          Just enable legacy boot option and disable UEFI boot option. This will let you boot the system with USB.
          If you can’t do that, tell the model of you laptop and we will show you in details.
