Aircrack-ng cracking Summary

Method:

1. Make sure that your wireless connection is Enabled: ifconfig checks whether wlan0 is enabled or other wireless adapters are enabled. If not, the subsequent steps cannot be performed.

You can use ifconfig-a to check whether there is a wireless adapter, and then run the ifconfig wlan0 up command to start the wireless adapter (wlan0 is the name of the wireless adapter found in ifconfig-)

2. Enable the NIC to be in the listening mode:

sudo airmon-ng start wlan0

3. view the wireless network and capture wireless data packets.

sudo airodump-ng mon0 

The wireless signal that you can search for is displayed. PWR indicates the signal value. A larger value indicates the stronger the signal, and ESSID indicates the signal name. ENC is the encryption method (WEP is the easiest way to crack, wpa and wpa2 can only crack brute force)

Find an essid you want to crack

4. After determining the target

sudo airodump-ng -c 6 --bssid target's MAC -w file mon0

-C 6 refers to the channel of this signal.

5. After receiving enough packets (that is, data), start cracking.

sudo aircrack-ng file-01.cap

If it is a wep-type password, it can be cracked directly after receiving enough packets (1 w)

For wpa/wpa2 type encryption, you must receive the handshake packet before you can start brute force cracking and use the password file (given an address: http://static.hackersgarage.com/darkc0de.lst.gz) if the password is complex enough, such a password file is not enough. You need to encrypt the file more complex by yourself.

sudo aircrack-ng -w dic file-01.cap

The password can be obtained after successful cracking.

Solution to mon0 is on channel-1, but the AP uses channel 1 during Ubuntu cracking

The last driver-name is The sudo modprobe iwlwifi corresponding to your NIC (you can find it using./scripts/driver-select)

If it is an intel 5100 wireless network card, use the 13.5 driver. A driver version that is too high may not be used.
