So, he started writing Ethereal and released the first version around 1998. The protocol at that time did not complete the primary requirements. In the late 1990s, Gerald Combs, a computer science graduate of the University of Missouri-Kansas City was working for a small ISP (Internet Service Provider). Hence, it’s by far one of the best packet analyzer tools and is utilized as a standard commercial tool by various government agencies, educational institutes, and non-profit organizations. Thanks to the global networking expert’s voluntary contribution, it continues to make updates for new technologies and encryption standards. The Wireshark project was initiated in 1998. Wireshark is the de-facto go-to tool for several network problems that vary from network troubleshooting, security issue examination, inspecting network traffic of a suspicious application, debugging protocol implementations, along with network protocol learning purposes, etc. Integrated decryption tools, such as WEP and WPA/WPA2, display the encrypted packets for a number of popular protocols. Numerous capture and trace file types, including CAP and ERF, are supported by Wireshark. The analysis of data packets might be done offline or in real-time. Wireshark, formerly known as Ethereal, shows information from hundreds of different protocols across all significant network types. It requires some sound knowledge of basic networking and is considered an essential tool for system administrators and network security experts.

It captures and displays packets in real-time for offline analysis in a human-readable format with microscopic details. Wireshark is an open-source and free network traffic inspection tool. Hacking Activity: Sniff network traffic.Below is the list of filters used in Wireshark:.
