This configuration is what is known as promiscuous mode, at least for most network adapters. A software packet sniffer configures the network interface so that is passes all network traffic. It is possible for any network interface attached to a network to receive every piece of network traffic that flows by, however, most are not configured to do so. Software packet sniffers are more common these days as they are open source. Ideally, a hardware packet analyzer stores the collected packets or forwards them on to a collector that logs the data collected by the hardware packet sniffer for further examination. A hardware packet sniffer can ensure that there is no packet loss due to cause like filtering and routing. A hardware packet sniffer comes in handy when trying to examine traffic of a specific network segment. How Do Packet Sniffers Work? There are two main types of packet sniffers: Hardware Packet SniffersĪ hardware packet sniffer is designed to be plugged into a network and analyze it. Doing this requires that an attacker has the right privileges, of course, but these can often be obtained using a variety of other hacking tools, such as a man in the middle attack. This includes the contents of emails, passwords, and potentially even financial information. With the help of a Packet analyzer, an attacker can (potentially) read all of the information being passed across a network. The two types of packet sniffers are filtered and unfiltered, where filtered is the one where only specific data packets are collected leaving out some information and the unfiltered being where all the data packets are collected. Packet Sniffers, also known as a packet analyzer, are the tools used to perform packet sniffing. Because the technique is such a powerful way of accessing network traffic, including sensitive and confidential data, it has also become part of the hacker’s standard toolkit. However, Packet Sniffing also has less innocent uses. With the right privileges, it also gives them a detailed view of how devices connected to a network are communicating with each other, and so is invaluable when it comes to setting up strong security and encryption protocols in corporate environments. Network engineers can use it to diagnose and troubleshoot network problems or to gather statistics about the performance of a given network. Packet sniffing has many legitimate uses. Just like eavesdropping, during this process, data packets may be compromised by a third-party. These data packets travel along the network path and reach the receiver in its’ original form. When you transfer data to someone, it is broken down into small units called data packets.
