At Euroinnova, we\u2019d like to explain one of the <strong>major cyber security threats<\/strong> that currently exists. This attack is dangerous because, as a user, you won\u2019t realise that the cybercriminal is gathering information about you. For example, they will be able to see what you are typing at all times, with all the risks that entails.<\/p>\n<p>In this article, we will take a closer look at <strong>What is a man-in-the-middle attack?<\/strong> y <strong>how it works.<\/strong> What\u2019s more, we\u2019ll explore the different types available and give you a range of <strong>Tips for preventing a Man-in-the-Middle (MitM) attack.<\/strong> Are you interested in this topic? Read on, because we\u2019re about to get started.<\/p>\n<h2 id=\"que-es-un-ataque-man-in-the-middle\"><strong>What is a man-in-the-middle attack?<\/strong><\/h2>\n<p>To begin with, we need to know <strong>What does \u2018Man-in-the-Middle\u2019 mean?<\/strong> in Spanish. Well, it can be translated as <strong>\u201cthe man in the middle\u201d<\/strong>, which gives us a clear idea of what this is all about. It involves an attack in which the hacker intercepts the communication between two devices connected to the network.<\/p>\n<p>Let\u2019s look at an example. If you want to access a website, you need a router to set up your internet connection so that it links your screen to the website\u2019s server. Initially, this is a direct connection, but there may be a cybercriminal who <strong>comes between you and the server<\/strong>, recording all data traffic and stealing your personal information.<\/p>\n<p>In a <strong>Man-in-the-middle attack,<\/strong> The consequences can be very serious, as hackers can eavesdrop on communications and obtain confidential information that may be sensitive. For example, a cybercriminal could gain access to your passwords, log into your online banking account and steal your money. Thus, the danger of a <strong>Man-in-the-middle attack<\/strong> It\u2019s huge.<\/p>\n<h2 id=\"como-funciona-un-ataque-man-in-the-middle\"><strong>How does a man-in-the-middle attack work?<\/strong><\/h2>\n<p>In order to carry out a man-in-the-middle attack, the hacker must choose the medium through which they will operate. For example, they can intercept communications via the <strong>Wi-Fi network<\/strong> the one you\u2019re connected to, especially if it\u2019s a public network. However, it can also <strong>install malware on your computer<\/strong> or mobile phone via phishing.<\/p>\n<p>Once it has selected the necessary technique and is part of your communication flow, it will see all your interactions with the website or between you and the person you are chatting to. How does it do this? Because, by being in the middle of your communication with the server, it can <strong>to redirect traffic<\/strong> so that it also passes through your own device or your own server.<\/p>\n<p>Let\u2019s remember that, in this case, the user does not know they are being hacked \u2013 in other words, they haven\u2019t realised it. That is why they also use methods such as the <strong>pharming,<\/strong> which impersonate a brand or individual by creating a page identical to the original. This technique, carried out via email, is what we call <a href=\"https:\/\/www.euroinnova.com\/curso-ingenieria-social-phishing-hacking\" target=\"_blank\" rel=\"noopener\"><strong>phishing.<\/strong><\/a> And so, the victim falls into the trap without having the slightest idea.<\/p>\n<p>The aim is always to get you to enter your details on the attacker\u2019s website as if you believed it to be the genuine site. That way, they can <strong>save information such as your passwords or payment details.<\/strong> In other words, they will always find a way to get involved without drawing too much attention to themselves, so that you never suspect a thing.<\/p>\n<h2 id=\"tipos-de-ataque-man-in-the-middle\"><strong>Types of man-in-the-middle attacks<\/strong><\/h2>\n<p>It is worth knowing the different <strong>types of man-in-the-middle attacks,<\/strong> as this will enable us to know exactly what we are up against and take steps to avoid them. Knowledge is essential for putting in place the necessary strategies to protect our privacy and security.<\/p>\n<h3 id=\"dns-spoofing\"><strong>DNS spoofing<\/strong><\/h3>\n<p>This <strong>Man-in-the-middle (MitM) attack<\/strong> involves poisoning your cache in the <a href=\"https:\/\/tecnologia.euroinnova.com\/en\/dns\" target=\"_blank\" rel=\"noopener\"><strong>Domain Name System (DNS).<\/strong><\/a> In this way, we would visit a website \u2013 though we wouldn\u2019t actually visit it, as we would be redirected to malicious sites. The worst part is that we wouldn\u2019t notice anything unusual or any different content.<\/p>\n<h3 id=\"https-spoofing\"><strong>HTTPS Spoofing<\/strong><\/h3>\n<p>In this attack, we will be taken to a <strong>unencrypted page.<\/strong> How do they do it? Through a link on a third-party website or in an email. You\u2019ll think you\u2019re accessing an encrypted page, <strong>HTTPS,<\/strong> but in reality you\u2019ll be accessing a copy at <strong>HTTP,<\/strong> unencrypted. You\u2019ll enter your details there and log in, so they\u2019ll already have that information.<\/p>\n<h3 id=\"secuestro-de-correo-electronico\"><strong>Email hijacking<\/strong><\/h3>\n<p>If they manage to <strong>log in to your email<\/strong>, the possibilities will be endless. They\u2019ll be able to read all your messages, but they\u2019ll also have access to your social media passwords and other platforms you\u2019re registered with. So, using your email address, they\u2019ll be able to access your bank accounts, for example.<\/p>\n<h3 id=\"robo-de-cookies-del-navegador\"><strong>Theft of browser cookies<\/strong><\/h3>\n<p>The first thing you need to know is that the <strong>browser cookies<\/strong> They contain a lot of information about you: your login details, websites you\u2019ve visited, purchases you\u2019ve made and products you\u2019ve viewed. This makes them a very powerful tool for hackers, as they can obtain your personal information to sell to third parties and make a profit. Furthermore, they can also use this information to gain access to your accounts.<\/p>\n<h2 id=\"como-evitar-el-ataque-man-in-the-middle\"><strong>How can you prevent a man-in-the-middle attack?<\/strong><\/h2>\n<p>The first piece of advice is clear. If you don\u2019t want to fall victim to phishing, you must <strong>Be very careful when downloading apps<\/strong> or clicking on links you don\u2019t recognise. This tends to happen, above all, in emails. So always check that the sender of the email is genuine.<\/p>\n<p>Another thing you can do is <strong>do not connect to any public Wi-Fi networks,<\/strong> as anyone can gain access. Anything that is easy to access inevitably becomes easy for many cybercriminals too, who see these networks as the perfect breeding ground for carrying out such attacks.<\/p>\n<p>We are often tempted to download programmes onto our computers or apps onto our mobiles from websites that are neither well-known nor trustworthy. Enticed by the fact that these sites offer free downloads, we end up giving in to the temptation to download malicious files onto our devices. These files then allow them to gain access to our devices.<\/p>\n<p>Another aspect you might not realise is the <strong>HTTPS security protocol<\/strong> found on the web. This indicates that the website has a security certificate and encryption, which HTTP websites, by contrast, do not have. When you come across a website like this, do not hesitate to leave it immediately and treat it with the utmost suspicion, as they could steal a great deal of your personal information.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u00bfNo sabes qu\u00e9 es un ataque Man-in-the-Middle?
