Users who enter a website affected by DNS spoofing might think that they landed on a legitimate site unfortunately, they end up on a faux website often designed to steal login credentials. However, instead of altering the IP address, attackers modify domain names to redirect traffic to fake websites. Consequently, this makes unsuspecting users believe that they are communicating with a legitimate website or device while in reality, all of the data that they share during the interaction is gathered by cyber crooks.ĭNS spoofing is, in essence, quite similar to IP spoofing. IP spoofing occurs when cybercriminals alter the source IP address of a website or device to mask it. Here are a few examples of different MITM attack types. However, all types of MITM attacks include interception and decryption phases. Get NordPass Premium Types of man-in-the-middle attacksīad actors can launch a MITM attack in a variety of ways. In this instance, the attacker changed the domain name to from. More recently, on September 21, 2017, Equifax found that users were being redirected to a fake phishing site, another result of a MITM attack. In 2011, the Dutch certificate authority DigiNotar became a victim of fraudulent certificates used to break down the security walls of a site, with customers being none the wiser. In 2013, Nokia's Xpress Browser was discovered to be decrypting HTTPS traffic, which gave clear text access to its customers' encrypted traffic. During the decryption phase, hackers use various techniques to decrypt data, but more on those later. Decryptionīecause all two-way online traffic is SSL encrypted, bad actors need to decrypt it otherwise, the intercepted data remains unreadable, making it worthless. As soon as the victim connects to a malicious Wi-Fi network, the attacker gains a complete view of all the data exchange. In most cases, hackers can intercept communication by gaining control of a public Wi-Fi network or creating faux Wi-Fi hotspots. Interceptionĭuring the first stage of the MITM attack, a bad actor first has to intercept communications. How does a man-in-the-middle attack work?Ī MITM attack comprises two phases known as interception and decryption. Usually, the goal of the MITM is to steal sensitive data such as usernames, passwords, credit card numbers, email addresses, and other pieces of information that attackers can use to profit. However, in essence, a MITM attack can be defined as a malicious interception of communications. MITM attacks can take a variety of shapes and forms. What is a man-in-the-middle attack?Ī man-in-the-middle (MITM) attack is a type of cyberattack during which bad actors eavesdrop on a conversation between a user and an application. One such threat is known as a man-in-the-middle attack - a type of attack where a bad actor secretly intercepts online communications between two people. The online world is full of security threats.
