Hack Wifi or Wireless networks-2

Welcome friends, in my previous post i have introduced the topic " How to hack the wifi or wireless Networks" in which i have explained the various wireless scanning tools with their download links. Today i will explain you how to use them. So today we will discuss scanning of wireless networks so that we can get the list of wireless networks around us and we can try our hacks on them. So guys lets continue Hacking Wireless Networks - Part- 2.

in previous post i have given you the list of topics that we cover in hacking wireless networks so lets continue the second topic.

2. Scanning the Wireless Networks or Wifi Networks

What is meant by scanning wireless networks? 

First of all we have to locate all the wireless networks
 around us. For this we have to do the scan for
 wireless networks its pity similar like we scan with
 antivirus for viruses in our system. Similarly we 
look for wireless networks around us with wireless 
scanning tools that i have mentioned in previous post

in this i have mentioned a lot of hack tools to scan
 the wireless networks but as i have said earlier my 
favorite is NetStumbler. Let's discuss now how to use
 NetStumbler?

Download NetStumbler from previous post:http://nishobdoblog.blogspot.com/2012/05/hack-wifi-or-wireless-networks.html

How to use NetStumbler for Scanning Wireless 
Networks?

1. Download the NetStumbler and Install it.

2. Run the NetStumbler. Then it will automatically 
starts scanning the wireless Networks around you.

3. Once its completed, you will see the complete list
 of wireless networks around you as shown in the snapshot below:

List of Wireless Networks Scanned by NetStumbler

 There you will see different columns such as MAC, 
SSID, SPEED, VENDOR, TYPE and much more...

4. Now select anyone of the MAC address that you wish to
 hack and want to explore more about that. If you click on 
the MAC address of one of the discovered wireless networks
 under channels, you will see a graph that shows the
 wireless network’s signal strength. The more green and 
the less spaces are there,it indicates better is signal strength.

5. As you can see NetStumbler provides a lot more than
 just the name (SSID) of the wireless network. It provides
 the MAC address, Channelnumber, encryption type, and
 a bunch more. All of these come in use when we decides
 that we wants to get in the secured network by cracking
 the encryption. 

There are two most common types of Encryption Methods
 used by Wireless Networks:

a. WEP (Wired Equivalent Privacy) – WEP isn’t 
considered safe anymore. Many flaws have been 
discovered that allow hackers to crack a WEP key 
easily. I will explain how to hack the WEP in next 
tutorial so guys keep reading..

b. WAP (Wireless Application Protocol) – WAP is
 the currently the most secure and best option to 
secure your wireless network. It’s not as easily
 cracked as WEP because the only way to retrieve a
 WAP key is
to use a brute-force or dictionary attack. If your 
key is secure enough, a dictionary attack won’t work
 and it could take decades to crack it if you brute-force 
it. This is why most hackers don’t even bother. 
But I will explain you smarter ways to hack WAP 
keys also rather than these noobish methods. I will
 explain this in my next consecutive  tutorials. So 
guys keep visiting.

Thats all about scanning the wireless networks, if
 you want that i should explain the other tools then
 please post in comments. I can explain them in
 future on demand.

Now how can protect our wireless network from
 scanned by NetStumber.

How to Protect yourself from NetStumbler?

1. Don not broadcast your SSID.

2. Always try to use stronger passwords like 
atleast one digit, one special character, uppercase
 letters mixed with lowercase letters.

3. But second point doesn't matter much so try to
 use better encryption method i.e. WAP to password 
protect your wireless Network.

So guys that's all for today , I hope you all have
 liked it. So keep visiting to know more about hacking and Full version software's Bye.
