Packet sniffing is a technique of identifying and monitoring packet data as they travel through a network. Although packet sniffing technologies are used by network administrators to monitor and verify network traffic, hackers may employ similar tools for unethical objectives. A WIFI adapter with monitor mode and packet sniffing capability is the most crucial item for packet sniffing. It is recommended to use a guest operating system, such as Kali Linux, to carry out packet sniffing, and a person must be familiar not only with using terminals and sniffer tools such as Wireshark, Ettercap, Driftnet, etc. but also with network layer protocols. There are both ethical and unethical uses for packet sniffing. Network vulnerabilities, for instance, can be found by both monitoring network traffic and detecting network problems. For unethical purposes, this could allow the theft of sensitive data, including login information, the list of websites visited, and the information accessed. A sniffer can be detected on a network by looking for unusual traffic patterns, a high rate of activity, and a network that is unprotected by firewalls or passwords and is located in public areas or by using a straightforward method such as building a Nmap sniffer script for a specific gateway.
