Description:
To crack WPA/WPA2 PSK you need to capture a ‘Handshake’ . The best way to this packet the attacker needs to disconnect a connected client currently on the network (if the attacker keeps on repeating this part, it will be a DoS to the user). Once the key packet has been captured, it is time to start an offline dictionary attack. If the network key is in the dictionary, its just a question of waiting to process the dictionary file. From here, the attacker can use that key to decrypt the captured data from before, and now is able to ‘read’ it as well as join the network. If there isn't a connected client - you cant do this. If the network key isn't in the dictionary file - you cant do this. You can speed the the cracking process by creating pre-calculated hash files (see results - for how much faster!).
In this video, g0tmi1k shows us a demo of Aircrack-NG vs coWPAtty.
You can read the full blog post here.Comparing Aircrack-ng versus coWPAtty, in the time it takes to crack a WPA2 PSK key.
It shows 4 different cracks, the time taken and speed of the crack (see results).
> Aircrack-ng (Dictionary)
> Aircrack-ng & airolib-ng (Pre-computed hashes)
> coWPAtty (Dictionary)
> coWPAtty & Genpmk (Pre-computed hashes)
Thanks go out to g0tmi1k for referring this video to us.

Thanx for your hard work. I've got a sandybridge i3 with 8gb ram, would my speed increase if i had the wordlist and cap file on external 7200rpm drive, my internal is same speed, didn't know if another platter would help, i got a gig list of passes, when i run batch, yeah, takes forever, is there a way to not have to run airolib for new essids? each time? i've tried pyrit install few times but always kept getting errors, even when off their site or from synaptic, LTdan or just go hashcat?
Niceeee
you use aircrack and airolib both with a dictionary. What about piping crunch or jtr to get the key? I don't get why everyone post a videos of the simple shit.. yeah if you have the password and cant crack it use a mac lol
