4. First Step Towards hacking of wifi (Modes of wireless cards)

Hello friends, This post is going to be more interesting because we are going to see everything practically from now. For hacking or performing penetration testing on the wifi networks we does not require much more things. We need these three things for attacking on any wifi network.

1. MAC(Media Access Control)  Address of the router
2. Channel on which wifi is operating
3. Name of the wifi

We are going to perform all our practicals using kali linux Operating System which we have installed on our VM Ware. We need a wireless adapter or wifi card which is supported or capable of packet injection for doing these practicals.

Modes of wireless card 
Generally, there are two modes present in the wifi card.
The first one is Managed mode and the second one is monitor mode.
In managed mode, we can simply connect to a wifi network if we know the password of that wifi, while in Monitor mode we can perform penetration testing and different kinds of attacks on the wifi network like bruteforce or dictionary attack.
For checking in which mode your wifi card is open your terminal and the command is:  "iwconfig" without semicolon as shown below.

You can simply put your wifi card in monitor mode as:
airmon-ng start wlan0

In our next post we wil know how to find out MAC Address, channel and essid of any access point which is present nearby us.
Thank yuh.. have a nice day...
