Sniffing is a method of monitoring and capturing data packets that pass through a network. It's also known as "wiretapping" for computer networks. Sniffing can be used by network administrators to monitor and troubleshoot network traffic. However, attackers can also use sniffers to capture data packets that contain sensitive information, such as passwords and account information. Sniffing can be done using software or hardware devices. The most common type of sniffing is done with a packet analyzer, which is a software program that can capture and decode the data. Sniffing attacks focus on stealing customer information. Attackers exploit this by injecting traffic into the Local Area Network (LAN) to enable sniffing. Common examples of active sniffing include MAC flooding, DNS (Domain Name Servers) spoofing, and ARP (address resolution protocol) spoofing.
