Common Techniques Used in Man in the Middle Attacks

Man in the Middle (MitM) attacks involve various techniques to intercept and manipulate communications between two parties without their knowledge. Here are some of the common techniques used by attackers:

1. ARP Spoofing

In an ARP spoofing attack, the attacker manipulates the Address Resolution Protocol (ARP) on a local network to associate their MAC address with the IP address of the targeted device. This allows them to intercept and redirect network traffic.

2. DNS Spoofing

DNS spoofing involves manipulating the Domain Name System (DNS) to redirect the victim's requests to a fraudulent website controlled by the attacker. This allows the attacker to intercept and alter the communication between the victim and the intended server.

3. SSL Stripping

SSL stripping is a technique where the attacker downgrades a secure connection (HTTPS) to an unsecured connection (HTTP), making it vulnerable to interception. The attacker can then capture sensitive information exchanged between the victim and the server.

4. Wi-Fi Eavesdropping

Attackers can set up rogue Wi-Fi access points or join insecure public Wi-Fi networks to intercept and monitor communications. This allows them to capture sensitive data transmitted over the network.

5. Session Hijacking

In a session hijacking attack, the attacker steals the session cookie or session ID of a user and uses it to impersonate their identity. This allows the attacker to gain unauthorised access to the user's accounts and perform malicious activities.

6. Malware Injection

Attackers can infect a victim's device with malware, such as keyloggers or spyware, to capture sensitive information, including login credentials and financial data. This malware can be delivered through malicious email attachments, infected websites, or compromised software.

These are just a few of the common techniques used in Man in the Middle attacks. Attackers are constantly developing new methods to exploit vulnerabilities and intercept communications, highlighting the importance of staying informed and taking necessary precautions.
