it is able to crack and recover WEP/WPA/WPS keys easily.
It can also run other network based attacks on wireless or Ethernet based networks.
For cracking WPA/WPA2, it uses WPS based on dictionary based attacks.
For WEP cracking, it uses Fragmentation, Chop-Chop, Caffe-Latte, Hirte, ARP Request Replay or WPS attack.
CoWPAtty is another nice wireless password cracking tool.
It is an automated dictionary attack tool for WPA-PSK to crack the passwords.
It runs on Linux OS and offers a less interesting command line interface to work with.
It runs on a word-list containing thousands of password to use in the attack.
If the password is in the password’s word-list, this tool will surely crack the password.
But this tool is slow and speed depends on the word list and password’s strength.
Another reason for slow process is that the hash uses SHA1 with a seed of SSID.
It means the same password will have a different SSIM.
So, you cannot simply use the rainbow table against all access points.
So, the tool uses the password dictionary and generates the hash for each word contained in the dictionary by using the SSID.
This tool is simple to use with available commands.
Airjack is a Wi-Fi 802.11 packet injection tool.
It is used to perform DOS attack and MIM attack.

Limited usability but works awesome on supported WLAN cards.
NetStumbler is another wireless password cracking tool available only for Windows platform.
It helps in finding open wireless access points. This tool is freely available.
Basically NetStumbler is used for wardriving, verifying network configurations, finding locations with a poor network, detecting unauthorized access points, and more.
This tool is not very effective now.
Main reason is that last stable release of the tool was back in April 2004 around 11 years ago.
So, it does not work with 64-bit Windows OS.
It can also be easily detected with most of the wireless intrusion detection systems available.
So, you can use this tool for learning purpose on home network to see how it works.
inSSIDer is one of the most popular Wi-Fi scanner for Microsoft Windows and OS X platforms.
This tool was released under open source license and also awarded as “Best Open Source Software in Networking”.
