The Man in the Middle attack is an offensive cyber approach that consists of intercepting a communication between web connection points to open strategic windows that allow the attacker to operate fraud. Ivan de Souza May 2, 20 | 7 min read man in the middle attack Different walks of life carry risks, and the digital world is no exception. In this modern universe, it is likely at some point you will have to face the dreaded hackers , South Africa Phone Number List which could cause unfortunate damage to your website, including the loss of information. The practices and techniques of these contemporary pirates are numerous and diverse. One of these is called Man in the Midle , which consists of an attack through an intermediary, which explains the reason for its name. When a hacker wants to steal information from a site, he steals what he needs through this system at the time of a data exchange or a link. The Man in the Middle is a usurper, since he impersonates any of the parties that legally receives any file .

In this way, it appropriates data that it was not authorized to access, such as bank accesses and passwords, for example. Yes, it is a great danger. Luckily, it is possible to deal with this threat by having a very good understanding of what it is about in the first place, as well as by applying certain effective methods. That said, in the next few lines we will delve into the characteristics of this cyber-hacking practice and we will give you the advice that you should follow so as not to be a victim of it. Take note! How does the Man in the Middle attack operate and how does it harm a website? The attack could be carried out in different ways, and so it is worth being prepared for each one.

The serious thing, in the first instance, is that it interferes from the DNS server , and if it has the opportunity, it will manipulate all the cache that is in the entries. If a website is not protected, everything inside it is vulnerable . This includes the IP address from where you operate to the servers and logs that generate the entries. The fraud tries to enter without being detected, thus obtaining the ability to bend the allowed accesses. Thanks to its deceptive methods, the scammer makes you believe that it is a regular user, even a regular customer who leaves complete data and fills out forms. The objective of all this is to observe the operation and get hold of useful information.

It is not difficult for a Man in the Middle to find passwords for banking pages, steal users and emails linked to the records and even modify the messages that a user sends to the page in question. It is also common for him to use emails, a common form of scam, in which both parties unconsciously provide a lot of data and could be being observed by the usurper, who waits for the right moment to break into the conversation. The way in which it does it is quite simple, since it is enough to impersonate a user, and for that it uses the data that it has been stealing previously . Another worrying aspect is that those records it steals are not only used illegally, they could also be distributed . Normally, the usurped is the provider. The hacker should convince the client that he has to put his money in an account that is not the official one. The fraud is carried out because this person will not suspect anything, since in theory they have contacted an official account. In these moments, communication becomes a double-edged sword, as it goes from being a useful and manageable tool to acquire goods and services to being an element that would make you lose money. All this tells us that the attack, in addition to the data theft itself, can affect the positioning of a website and its conversions . A page that is violated also loses its reputation and reliability, at least moderately, which would affect its SEO positioning . At the same time, as it is less secure, it is also less attractive to users, thus losing the ability to generate business opportunities. In what situations can a Man in the Middle attack be generated? Next, we will review the different ways this scam can occur: Man in the Browser Attack In this case, the attacker places a malware on the browser in order to get hold of all the valuable data of the users. This occurs in browsers that have not been properly updated, making them vulnerable to infiltrations .

Generally, a Trojan horse, also called a Trojan virus or simply Trojan, is used to intercept and manipulate on the fly the calls between the main application executable (such as the browser) and its security mechanisms or libraries. The most frequent goal of this onslaught is to cause financial fraud. DHCP server attack In a DHCP server attack, the hacker transmits a large number of DHCP request messages (the protocol by which an IP address is assigned) with spoofed source MAC addresses. If the legitimate DHCP server on the network starts responding to all these bogus messages, the available IP addresses in the DHCP server’s range will be exhausted in a very short amount of time. DNS server attack In this mode, hackers manipulate the cache entries of a DNS server to emit false destination addresses. If they are successful, they could send users to any other site without their realizing it. This occurs mainly in those servers with outdated software . ARP cache poisoning With this strategy, attackers intercept communication between network devices, posing as one side of the communication channel: provider or customer. This seriously jeopardizes the information of both parties. If this operation is successful, the attacker will be able to: Track channels and steal data (except if it is transferred through an encrypted channel such as HTTPS);Hijack the session where the user is currently connected Modify communication and send a malicious file to the workstation; Cause Distributed Denial of Service ( DDoS ) ⁠, meaning attackers can provide the MAC address of a server they want to DDoS attack, rather than their own machine. If they do this for a large number of IP addresses, the destination server will be bombarded with traffic.

Wireless Network Simulation In this case, the hacker configures your computer so that other devices perceive it as a Wi-Fi signal, like that of a cafe or an airport. If your device connects to this fraudulent network, you will put all your information in serious danger. How to protect your website from a Man in the Middle attack? If you’ve read all of this information, and you have clients that you normally interact with from your website, you’re probably wondering how you can avoid falling victim to these annoying attacks. First of all, you have to know that protecting yourself goes much further than choosing a good host . The key is to take the necessary steps before you become a victim.
