Man In The Middle Attack: Definition, Types and How to Prevent It

What is Man In The Middle Attack?

Man In The Middle Attack or MITM is a type of cyber attack where an attacker infiltrates between two parties’ communications that should be private. In this attack, attackers can steal sensitive data such as login information, passwords and even credit card information. Man in the Middle Attack is one of the attacks that is often used because it takes advantage of negligence in connections that are considered secure.

Types of Man In The Middle Attack

There are several types of man in the middle attacks that are commonly used by attackers to steal data, including:

1. IP Spoofing

In this method, attackers fake their IP addresses so that they look like real users. That way, attackers can access networks and data that should not be accessed.

2. DNS Spoofing

In this attack, attackers change the DNS address to direct users to a fake site that looks like the real site. On this fake site, attackers can steal information entered by users.

3. HTTPS Spoofing

This attack involves creating a fake HTTPS site that looks like the real site. This fake HTTPS makes users feel safe, even though their data is being stolen.

4. Wi-Fi Eavesdropping

This attack occurs when an attacker takes advantage of an unsecured public Wi-Fi network. The attacker can eavesdrop on data sent over the network.

5. SSL Stripping

SSL Stripping is a method that forces users to use an unsecured HTTP connection instead of HTTPS. That way, data can be stolen without detection.

Purpose of Man In The Middle Attack

The purpose of a Man in the Middle Attack varies widely, but is basically to gain unauthorized access to sensitive data. Some common goals of this attack include:

Stealing Personal Data

Personal data such as credit card numbers, email addresses and passwords are often the main targets.

Accessing Systems

Attackers can also use this attack to break into systems that require authentication.

Changing Data

In addition to stealing data, attackers can also manipulate information sent between two parties.

Extortion and Fraud

The stolen data can be used to blackmail victims or commit fraud.

How Man In The Middle Attack Works

A Man in the Middle Attack is a fairly simple yet highly effective attack. Essentially, the attacker enters as an undetected third party between two communicating parties. Here are the stages of how MITM works:

Infiltration

The attacker first infiltrates the network or connection between two devices. This can be through a public Wi-Fi network or a spoofing method that directs communication to the attacker’s device.

Data Monitoring

Once connected, the attacker will monitor and analyze the data being sent. This allows them to obtain information such as usernames, passwords or even credit card numbers.

Data Manipulation

In addition to stealing, attackers can also change the data being sent to direct victims to fake sites or gain deeper access to accounts or networks.

Attack Completion

After obtaining data or changing information to their liking, attackers usually end the attack by closing the connection, leaving the victim unaware that their data has been stolen.

How to Prevent Man In The Middle Attacks

Preventing man in the middle attacks requires a combination of strong security techniques and user awareness. Here are some steps you can take to prevent MITM:

1. Use HTTPS

Make sure all important internet communications are always conducted over HTTPS, which provides an extra layer of encryption for the data.

2. Use a VPN

A Virtual Private Network (VPN) is one of the best ways to protect online communications from MITM attacks. A VPN encrypts your internet connection, making it difficult to infiltrate.

3. Avoid Public Wi-Fi

When possible, avoid using public Wi-Fi when accessing sensitive information. Public Wi-Fi is particularly vulnerable to MITM attacks.

4. Update SSL Certificates

Make sure your site always has an updated SSL certificate to provide extra security for your visitors.

5. Use Two-Factor Authentication

By using two-factor authentication, users must complete two steps of verification before they can log in to their accounts. This makes it difficult for attackers to steal login information even if they do manage to.

6. Keep Your Security System Updated

Attackers are constantly developing new techniques to steal data. Make sure your systems and devices are always updated with the latest security updates.

Conclusion

Man in the Middle Attack is one of the most dangerous threats in cyberspace. This attack is not only financially detrimental, but can also result in the loss of valuable data. By understanding the types, how it works and prevention of MITM, we can protect ourselves from these increasingly sophisticated cyber attacks.
