Some Practical ARP Poisoning with Scapy, IPTables, and BurpAll the computers on my environment are using windows 7 and some use windows 8. But as for the backup drive, it is just that. Can anyone give me a hand please. When an attack is detected, you should be able to open a dialog allowing you to stop blocking attacks from the particular trusted IP address as follows:. I mean, you will not see this opportunity if the firewall is set to automatic filtering? If I have understood it correctly, you could swift to interactive firewall to resolve a situationregarding a poisoning attack, and in those cases, where it is a know and trusted ip, for then to set your firewall in automatic mode with exceptions, if necessary. No, the option to set an IP address as trusted upon attack detection shows up regardless of what firewall mode is used. TomFace and Marcos, thanks for the feedback on my post.

How to Build an ARP Spoofer in Python using Scapy
In a switched network environment, packets are sent to their destination port by MAC address. This process requires that the systems on the network maintain a table associating MAC addresses to ports. In a switched environment, packets are only sent to devices that they are meant for. Even in this switched environment, there are ways to sniff other devices' packets. One such way is to spoof your MAC address and poison the arp table. Since arp keeps no state information, the arp cache can be overwritten unless an entry is explicitly marked as permanent. Arp cache poisoning puts the attacker in position to intercept communications between the two computers. Computer A believes it is communicating with Computer B, but because of the poisoned arp table, the communication actually goes to the attacker's computer. The attacker can then either respond to Computer A pretending to be Computer Bor simply forward the packets to its intended destination, but only after the packet information is captured and logged for later use by the attacker. Likewise, the response from Computer B can be captured and logged by the attacker, who has also used Arp poisoning to make Computer B think the attacker's computer is Computer A. This type of attack is known as Man in the Middle attack. This article covers a number of tools used in arp cache poisoning attacks, including ettercap, arpspoof, nemesis, p0f, dsniff, and scapy. For arp cache poisoning to take place, the attacker needs to be in the same network segment as the systems under attack. Ettercap is a suite for man in the middle attacks on a local LAN. It features sniffing of live connections, content filtering on the fly, and more. Ettercap supports active and passive dissection of many protocols some of several protocols. The following command:. The dsniff suite includes tools such as dsniff, filesnarf, mailsnarf, nsgsnarf, urlsnard, and webspy, which passively monitor a network for interesting data. Arpspoof, dnsspoof, and macof tools facilitate the interception of network traffic normally unavailable to an attacker due to layer-2 switching. Specifying the interface is optional but required if more than one interface is present. The -t option specifies the particular host to arp poison; if the host is not specified, all hosts on the LAN will be poisoned. The host can be the default gateway, and this will keep the target from communicating beyond the local segment. Libnet is a generic networking API that provides access to several protocols. To better understand the arp cache poisoning process, consider an alternative tool called Nemesis. By crafting your own packet using Nemesis, you can see how the arp cache poisoning works:.
ARP poisoning using Python and Scapy
How to perform ARP Cache Poisoning with Scapy
Well, in brief, it is a method of gaining a man-in-the-middle situation. Technically speaking, it is a technique by which an attack sends a spoofed ARP packets false packets onto the network or specific hostsenabling the attacker to intercept, change or modify network traffic on the fly. Once you as an attacker are a man in the middle, you can literally intercept or change everything passes in or out of the victim's device. So, in this tutorial, we will write a Python script to do just that. In a regular network, all devices communicate normally to the gateway and then to the internet as shown in the following image:. Now the attacker needs to send ARP responses to both hosts:. Alright enough theory! Let's get started. Before anything else, we need to import the necessary modules:. Note: You need to have scapy library installed in your machine, head to this postor the official scapy website. At the beginning, I need to mention that we need to have IP routing i. There are many ways to enable IP route in various platforms, however, I made a python module here for you to enable IP routing in Windows, without worrying about anything. The function below handles enabling IP routing in all platforms:. Now, let's get into the cool stuff. First, we need a utility function that enables us to get the MAC address of any machine in the network:. We use Scapy's srp function that sends requests as packets and keep listening for responses, in this case, we're sending ARP requests and listening for any ARP responses. Second, we gonna create a function that does the core work of this tutorial, given a target IP address and a host IP addressit changes the ARP cache of the target IP address saying that we have the host's IP address :. Once we want to stop the attack, we need to re-assign the real addresses to target device as well as the gatewayif we don't do that, the victim will loose internet connection and it will be obvious that something happened, we don't wanna do that, we will send seven legitimate ARP reply packets common practice sequentially:. This was similar to the spoof function, the only difference is that it is sending few legitimate packets. In other words, it is sending true information. I ran the script on a linux machine, here is a screenshot of my result:. In this example, I have used my personal computer as a victim, if you try to check your ARP cache :. You will see that the attacker's MAC address in this case "
