The attack takes place in between two legitimately communicating hosts, allowing the attacker to “listen” to a conversation they should normally not be able to listen to, hence the name “man-in-the-middle.” There are a number of ways that an attacker can carry out a MitM attack. One common method is to use a fake Wi-Fi hotspot. When a victim connects to the fake hotspot, the attacker can intercept all of the victim's traffic. Another method is to use a malicious proxy server. When a victim's browser sends a request to a website, the request is first sent to the proxy server. The proxy server can then modify the request before sending it on to the website. MitM attacks can be used to steal sensitive information, such as passwords, credit card numbers, and other personal information. They can also be used to inject malicious code into a victim's computer. There are a number of techniques that can be used to prevent MitM attacks. One common technique is to use a Virtual Private Network (VPN). A VPN encrypts all of a user's traffic, making it much more difficult for an attacker to intercept. Another technique is to use a security suite that includes a firewall and antivirus software. A firewall can help to block unauthorized access to a computer, and antivirus software can help to detect and remove malicious code. Here are some additional tips to help prevent MitM attacks: - **Be careful about which Wi-Fi networks you connect to.** If you're not sure whether a Wi-Fi network is secure, don't connect to it. - **Use a VPN when connecting to public Wi-Fi networks.** A VPN will encrypt your traffic, making it much more difficult for an attacker to intercept. - **Keep your software up to date.** Software updates often include security patches that can help to protect your computer from attack. - **Be careful about what information you share online.** Don't share your passwords, credit card numbers, or other sensitive information with anyone you don't know and trust. By following these tips, you can help to protect yourself from MitM attacks. --- Original Source: https://www.mindstick.com/forum/158548/how-does-a-man-in-the-middle-mitm-attack-work-and-what-are-the-techniques-to-prevent-it Copyright © MindStick Software Pvt.
