How to Crack Wi-Fi WPA and WPA2 and PSK passwords

The wireless networks are being deployed extensively these days. Both home and office wired networks are now being upgraded to Wi-Fi zones so that many users can connect simultaneously in a wire free environment. With comfort your security is being compromised. The WiFi networks makes use of wireless encryption like WEP, WPA, WPA 2 PSK etc. All these encryption algorithms provides security to IEEE 802.11 wireless networks.


Though WEP algorithm was introduced to provide privacy equivalent to wired networks its the most un secure and easily susceptible algorithm. The Wifi networks secured using WEP can be cracked within minutes with readily available software or hardware. Check this hardware for an example. That explains how insecure WEP algorithm is. Then came the WPA and WPA 2  that promised a secure connection via a stronger algoritm. Though these 2 algoritms are recommended it is still susceptible via software.

Wireless Security Auditor from Elcomsoft is a premium software that can crack WiFi WAP/WPA2 PSK passwords, intercept data packets and locate wireless networks. This app makes use of dictionary attack by searching lists of dictionary words and common phrases that can be found on the internet. Elcomsoft Wireless Security Auditor is undetectable by the Wi-Fi network being probed and WPA/WPA2-PSK passwords can be retrieved  in plain text.

In order to speed up password recovery/ discovery Wireless Security Auditor harness the power of GPU. This app supports graphics cards like NVIDIA  like GeForce and ATI video cards such as Radeon HD 4800 and 5000 series.
