Hostapd

• A tool that will help us creating and launching and access point.
• To do that we need a file called hostapd.conf
• For this we will require access point mode or AP mode enabled on our adapter which we will check by iw list
  
• From the above screenshot we can see the AP mode is enabled which means we can broadcast via our adapter.

• Here is the hostapd.conf file, containing all details.
  

Explaination of the hostapd.conf file :

1. interface : specifies which interface we are broadcasting on. (wlan0)
2. driver : this specifies the wifi standard we are going to use (nl80211)
3. ssid : name of the wifi
4. channel : the channel on which our wifi will be broadcasted
5. hw_mode : the frequency range of our adapter (g = 2.4GHz)
6. macaddr_acl : (acl = Access control list)
   • 0 : Allow all (any mac addr can join the network)
   • 1 : Use only white list (Only allow mac addresses in the list)
   • 2 : Use only black list (Do not allow mac addresses in the list)
7. auth_algs : (Authentication algorithms)
   • 1 : Open network (wifi without password)
   • 2 : Secure network
   • 3 : Mix of both

• Launched the hostapd.conf using hostapd tool
  

• From the above screenshot we can see different mac addresses our trying to access our AP
• This is the AP we created, we can change this AP into a rogueAP(malicious intent in AP) going further.

dnsmasq :

nano dnsmasq.conf

Explaination :

1. dhcp-range : this range can join out network
2. dhcp-option
   • 3 : configure gateway
   • 6 : configure DNS (we can also keep 8.8.8.8 -> google)

• Mode : Master (which means complete potential of the adapter is being used)
