A man-in-the-middle (MITM) attack is a type of cyber attack in which an attacker intercepts communications between two parties in order to gain access to sensitive information or to alter the content of the communication. This can be done through a variety of means, such as intercepting and manipulating traffic on a public WiFi network, or by installing malicious software on a device that allows the attacker to monitor and control the device's network traffic.
MITM attacks can be particularly dangerous because they often go undetected, as the parties involved in the communication are not aware that their communication has been intercepted. This can lead to sensitive information being compromised, or to the parties involved in the communication being misled or manipulated.
There are a number of ways to protect against MITM attacks, including using encrypted communications, implementing strong passwords and authentication measures, and regularly updating and patching software and devices. It is also important to be cautious when using public WiFi networks, as these can be more vulnerable to MITM attacks.
In summary, MITM attacks are a serious threat to the security and privacy of online communication. It is important to take steps to protect against these attacks in order to keep sensitive information safe and to ensure that your online activities are not compromised.
