![]() ![]() If you can’t follow the simple instructions for each system here: To do this we must first have it installed, in distributions such as Kali linux will suffice: Once this redirection is done we can run mitmproxy. Iptables -t nat -A PREROUTING -i wlan0 -p tcp -dport 80 -j REDIRECT -to-port 8080 Iptables -t nat -A PREROUTING -i eth0 -p tcp -dport 80 -j REDIRECT -to-port 8080 We will use the python API so that the modifications are made automatically.Īs we have said we need that the web petitions of the victims arrive to our port 8080 for this we will use iptables. Once we have the petition we will make the necessary changes and we will return it to the victim. In practice, what we will do is receive the requests sent to us by the victims and redirect them to port 8080 which is the one established for mitmproxy. It also has a python API to develop scripts and is well documented. This tool can be used to intercept, inspect, modify and reproduce web traffic. Once the ARP table has been poisoned, we will start to be able to capture requests, that is make our Man in the middle.įor this part we will use the tool mitmproxy. Inside the victim machine we can see how the MAC of the gateway is change by the MAC of our machine.Īrpspoof -r -i wlan0 -t 192.168.1.44 192.168.1.1 The operation of the tool is simple, the -r parameter indicates that it will capture traffic in both directions also needs the -i parameter with the network interface to use and finally the current gateway. As we see gateway of wlan0 is 192.168.43.1įirst make sure that packet forwarding is enabled: To know gateway of our interface we can use our arp table with the arp command. We will use the arpspoof tool installed by default in Kali linux To create the environment we will use a virtual machine as a victim.Īs already said we will use ARP poisoning, we will use it to supplant the gateway and thus receive all the requests of the devices of that network. From here, the attacker can steal data or launch a more sophisticated attack.įrom here we start the attack in a practical way. If the attacker managed to link his MAC address to a genuine IP address, he will start receiving any data that can be accessed via the IP address.These packets contain the MAC address of the attacker and the IP address of the victim in order to change the arp cache of the computers to establish the relationship of that MAC with that address ip. The attacker chooses his destination and starts sending ARP packets over the LAN.The attacker uses the ARP Spoofing tool and scans the MAC and IP addresses of the hosts of the target subnet.We will focus on ARP poisoning, as it is the most common and the one we will use in this example.Īn ARP poisoning attack works as follows: To supplant some communicator are used the techniques of ARP Poisoning, DNS Poisoning, Port Stealing, DHCP Spoofing, etc. Another way to carry out an attack of this type is creating a Wifi access point of our control since we would control the gateway. The way to perform the man in the middle is to supplant one of the communicators or the gateway (router) with which we would receive all requests. In this post we will make modifications to the answers that the victims receive. This allows the theft of data, reading and modification of communications.
