how to crack wifi passwords you never connected to

We wouldn't want to crack the encryption on anyone's personal device. Before you begin cracking make sure to find out if this is a company hotspot and get permission from the hiring company to try and break the password. Just as an example let's say the model has a default 8 digit pin. Since you read this how to you know that this hotspot could potentially have a default password. You notice an AP in your vicinity with SSID 'So-and-so's Hotspot'.

This will start up the wireless card in monitor mode so you can see what AP's are near without broadcasting any packets. Follow that command with airmon-ng start wlan0 followed by airodump-ng mon0. You need to kill any processes that may interfere with the wireless card. You first boot up Backtrack and plug your Alfa AWUS036H wireless card in. Say you have been hired by a company to do a penetration test on their wireless infrastructure. Quicker as you may crack the password by brute force. Instead using John the Ripper to compute on the fly will will be It doesn't make much sense to use rainbow tables with this attackīecause you will still need to compute the tables based on SSID. My laptop can crank outĪbout 2,000 password attempts per second so that equals out to aroundġ4 hours of cracking time to go through every possible combination.

Total of 100,000,000 possible combinations. For example lets say we know there are only eight digits in the password. Once one has the handshake they just need to be able toĬrack it.
