Preperation Create Airolib Database (Optional)Īirolib-ng is designed to store and manage ESSID and password lists.

In the event of not successfully capturing in, we can either re-run the deauthentication attack against the same client or we can run the attack against a different client. However, we could use a deauthentication attack on a connected client to speed up the process, which is what we will do aireplay-ng -0 1 -a 34:08:04:09:3D:38 -c 00:18:4D:1D:A8:1F mon0Īfter conducting the attack, you can look in the upper right hand corner of the airodump-ng output and should see the we hopefully captured the complete 4-way handshake. We could passively capture the WPA handshake by allowing airodump-ng to run until a new wireless client connects and authenticates to our target network. Our goal is to capture the WPA 4-way handshake, which takes place when a wireless client connects and authenticates to the access point. This will start airodump-ng, listening on Channel 3 and filtering on the BSSID and saving the output to wep1. Now, an Airodump sniffing session needs to be started and write the capture file to the disk for usage by Aircrack-ng for breaking the WEP airodump-ng -c 3 –bssid 34:08:04:09:3D:38 -w wpa-psk mon0 This will set wlan0 into monitor mode as mon0 on channel 3 Recon

The first step in every attack scenario is to place the wireless interface in monitor mode on the same channel as the access airmon-ng start wlan0 3 A large dictionary can to hours to days to process due to the computational intensity of brute forcing. The impact of having to use the brute force approach is a substantial impact to efficiency. OverviewĪlthough WPA-encrypted networks do not suffer from the same cryptographic vulnerabilities as WEP networks, they can still sometimes be easier to crack due to users picking weak passwords. The primary difference between cracking WEP and WPA/WPA2 is that while statistical methods can be used for speeding up the cracking of WEP pre-shared keys, only brute force can be used for WPA/WPA2 PSK. We will show you how to use aircrack-ng by itself, with an airolib-ng database and with John the Ripper to crack WPA/WPA2 passwords In this post we are are going to move on to cracking WPA/WPA2 Pre-shared keys using aircrack-ng.
