WiFi hacking and security

Netstumbler for wifi hacking and security

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.

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, Channel number,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.
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.

Thats all about scanning the wireless networks,
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
