Unfiltered: Here, the sniffer tool will capture all possible packets and put them in the local hard drive for evaluation Sniffer tools can be largely configured in two ways:įiltered: In this configuration, the sniffer tool captures packets that contain explicitly mentioned data elements The name comes from their dedicated purpose to explore or 'sniff' streams of data packets flowing between the sender and the receiver. The attacker does not need to send any special packets or exploit any vulnerabilitiesĪny hardware or software monitoring network traffic is a packet sniffer. Passive sniffing: Passive sniffing involves monitoring traffic that is already passing through a network device such as a switch or router. IP sniffing is divided into two categories:Īctive sniffing: In active sniffing, the attacker injects address resolution protocols (ARPs) into a network to redirect traffic to the attacker's machine Network administrators and monitoring teams can use it to monitor and validate network traffic. However, the technique has advantages as well. Using this technique, cybercriminals 'sniff' for unencrypted information such as credentials, passwords, or confidential data over an unsecured network. IP sniffing can be used to track the activities of users on a network or to steal information from communications. The traffic is captured in packets, which are small chunks of data that are sent between devices on a network.

IP sniffing is a technique used to intercept, monitor and log traffic over a TCP/IP network. This article will discuss what IP sniffing is, how it works and how to protect your organization from this type of attack. Secure your industrial networks, devices, and production linesĬybercriminals are always looking for new strategies to hack corporate employee credentials and IP sniffing has become a popular method for stealing sensitive data.
