Reverse engineering is the process of taking apart and analyzing an existing product, system, or software to understand how it works and to gain detailed information about its design and structure. It involves breaking down the object into its component parts, extracting design information, and often recreating or improving the original product. This technique is used across various fields, including software, mechanical, electrical, and architectural engineering, to learn from existing designs, adapt technologies, or create replacements when original parts are no longer available.

Network reverse engineering

For this, Wireshark is very useful. It is a GUI tool that can capture and display network traffic. It also has a lot of decoders for different network protocols.
