What Is Man-In-The-Middle Attack (Mitm)

Attackers can use a MITM attack to steal credentials and personal information, spy on the victim, sabotage communications and damage data. It is important to take precautions to prevent MITM attacks before they occur and to try to detect them as soon as they occur. Knowing the tell-tale signs of a MitM attack and introducing detection methods can help you spot the attack before it does any harm.

A man-in-the-middle attack (MITM) is a form of cyberattack in which important data is intercepted by an attacker with a technique that interferes with the communication process. Since the early 1980s, computer scientists have been looking for ways to prevent threat actors from manipulating or eavesdropping on communications. Because MITM is protected by encryption if successful an attacker can redirect traffic through phishing sites that are designed to appear legitimate, redirect it to its intended destination, and collect records, which means that detection of such attacks is difficult.

An attacker can be a passive listener who steals your secrets in your conversation or an active participant who changes the content of your messages to embody the person or system you think you are talking to. If an attacker steals session cookies, malware, browser hijacking, cross-site scripting (XSS) attacks on popular web applications or executes malicious JavaScript, he or she can log in to your account, listen to the conversation and pretend to be you. An attacker can intercept traffic on a public, unsecured Wi-Fi network or he can create a Wi-Fi network with a shared name to get people to connect to it and steal credentials, credit card numbers and other information that users send over the network.

An attacker gains access to a user’s e-mail account and observes the transactions on the account. This is used to redirect traffic from the local network to the attacker’s system. This method is the most common form of MITM- attack but it is also the most dangerous because the attackers have intimate knowledge of company security systems, policies and procedures which means that it is easier to infiltrate the infrastructure to falsify communications.

Sophisticated tools to perform successful man-in-the-middle attacks are available to hackers through penetration tests. For example, Metasploit is a penetration testing tool that supports many types of MITM attacks immediately and tools like Armitage offer an easy-to-use graphical user interface for carrying out such attacks. Depending on the vulnerability used, the existing IT security infrastructure and users “knowledge of potential threats to IT security detecting man-in-the-mid lot attacks can be difficult, but prevention is better than cure.

Man-in-the-mid-range (MITM) attacks pose a serious threat to application security. If there are no safeguards, these attacks are easy to carry out, difficult to detect and reward attackers with access to a wealth of sensitive user and business information. Given the extent of the damage these attacks can cause, it will be crucial for economic actors to understand and identify their underlying vulnerabilities and to take preventive measures to protect their infrastructure from these attacks.

In this tutorial, we explain the basic idea of Man-in-the-Middle attacks (MITM) and demonstrate some examples of mitigation techniques. A man-in-the-middle attack is a type of eavesdropping attack in which an attacker interrupts an existing conversation or data transmission. In a man-in-the-middle attack, an attacker intercepts a message between two parties who believe they communicate with each other.

A man-in-the-middle attack ( MAEM) is a type of eavesdropping attack in which the entire conversation is controlled by the attacker. In a MITM attack, a third party gain access to communications between two other parties without any notice to either of them. MITM, also called a session hijacking attack has a great chance of success because the attacker can represent one of the two parties to the satisfaction of the other.

For example, when Gerald sends a message to Leila and intends it to be private, Max intercepts the message, reads and passes it on through a MITM attack to Leila. If Gerald wishes to transfer PS100 to Leila’s bank account, Max can intercept the transaction and replace Leila with his own account number and thus intercept the attack. In this case, he stands in the middle of Gerald and Leila’s bank accounts.

The attacker sends you a fake message that appears to be from your colleague, including the attacker’s public key. The attacker intercepts the message with his private key and decrypts it, modifies the message, encrypts it again with the public key and intercepts your colleague, who then forwards the message to you. You believe that the attacker has the public key of your colleagues and encrypt the message with it and send it to your colleague.

A man in the middle attack (MITM) is a general term for when the perpetrator places himself in a conversation between a user and an application, eavesdrops on one or both parties, and pretends a normal exchange of information is underway. As the name implies, the attacker sits in the middle of an attack on a cryptographic protocol and negotiates various cryptographic parameters between client and server.

Man-in-the-middle attacks can take two forms, one physical proximity to the target and the other malicious software (malware). The latter is referred to in the browser attacks as a man. The target is usually a user of a financial application, a SaaS business, an e-commerce website, or any other website where log in is required.
