airodump-ng
airodump-ng "is used for packet capture, capturing raw 802.11 frames."
Find APs to attack
sudo airodump-ng mon0
tip
Might want to add --band abg
to listen on all bands
Listen for handshake on specific wifi name
sudo airodump-ng wlan0mon --essid "Name of Corp Wifi"
tip
The #Data
field generally indicates how much traffic or activity is happening on that network, so I think it means it's a good target for handshake captures
Start listening for a handshake using specific BSSID and specific channel
sudo airodump-ng -c 1 --bssid 00:11:22:33:44:55 -w name-of-file-to-output mon0 --ignore-negative-one --channel 777
Now that you're taking a good dump (heh), you could speed the handshake-grabbing process along by disassociating clients using aireplay-ng!
