Detect and mitigate this attack to surf safely Once we have already learned how we can do this attack with Kali Linux easily and quickly, let’s see how we can mitigate this attack.

If we use these techniques to monitor other people’s systems, we are committing a crime. These techniques are only for private use within our own network, or in a network in which we have permission, logically these techniques can be applied for illegal purposes. For example, we have done the typical ping to Google, the attacking team has captured everything correctly. The next thing we must do is, for example, run Wireshark to capture all network packets and analyze them in search of interesting information or resort to the different plugins that Ettercap offers us, such as, for example, the remote web browser, where it will load us all the websites that the target visits. Next, we will open « Ettercap-graphical » and we will see a window similar to the following one. Sniffing and Spoofing «, since that is where we will find the necessary tools to carry out this computer attack. The first thing we must do, in the list of applications, is look for section « 9. Now the attacker How to do an ARP Poisoning attack with Kali Linux Once both the victim and the router have received the fake ARP packets, they will communicate with the attacker directly instead of with each other, and right now the attacker will be in the middle of the communication. But for the communication to be bidirectional it is also necessary to make the router believe that we are the victim, therefore, we will have to launch two ARP Poisoning attacks, one on the victim and the other on the router. Once the fake ARP packets are sent to the victim, they will believe that we are the router.Two well-known tools to carry out this task are Arpspoof and BetterCap, from the latter you have a complete tutorial in this article. You must make use of different tools, in order to create a fake ARP packet and send it to the victim.You must scan the entire local network in search of the victim’s IP address, to later launch the attack.The attacker must be within the same network as the victim, same wired network or same WiFi network.In order to perform an ARP Poisoning attack, it is necessary to meet certain requirements: The attacker will be able to continue routing all communications and obtain all the information, which is the most normal thing, in fact, he will be able to steal the victim’s cookies and impersonate him without the need to steal user accounts and passwords. Man in the Middle attack : if the attacker forwards the connections to the router to go to the Internet, we will be doing a MitM attack, obtaining all its network traffic for further study, in addition, the information sent or received could also be modified on the fly the victim, in fact, one of the most dangerous attacks is SSL Stripping, whereby an attacker is able to “lift” HTTPS traffic and convert it to HTTP to spy on all communications.DoS attack : if the attacker does not forward the connections to the router to go to the Internet, we will be doing a denial of service to the victim, that is, we will be leaving him without an Internet connection.In this way, a victim device could unknowingly send all its network traffic to this attacker, and carry out two different types of attacks: The ARP Poisoning attack consists of poisoning the ARP table of a victim, making it believe that the router is the attacker, with the aim that the victim forwards all its traffic to this attacker to perform a sniffing of each and every one of the connections that perform. The ARP protocol was not designed with the aim of being secure, so it does not verify at any time that the response to an ARP request really comes from a legitimate host, anyone could impersonate another host easily and quickly, performing an ARP Poisoning attack. ARP Poisoning attacks are specifically focused on this entry, and now we will explain why. One of the most important entries in the ARP table is the one displayed by the router, usually the first IP address on the subnet. In this way, if a certain computer does not know the MAC of an IP address, it will have to send an ARP request packet, requesting the corresponding MAC address from other computers. All computers keep this ARP table as a cache, so it will be temporarily renewed or as new computers appear with which we want to communicate, that is, it is a dynamic table and it changes depending on the communications that we are going to make.
