Overview of Ghidra

Ghidra is a software reverse engineering (SRE) framework developed by the National Security Agency (NSA). It is designed for analyzing compiled code of various platforms, including Windows, macOS, and Linux, to understand its functionality. Ghidra's primary purpose is to aid in understanding how certain software behaves, which is especially crucial in cybersecurity. It includes features like disassemblers, decompilers, graphing, and scripting capabilities. For instance, a cybersecurity analyst might use Ghidra to disassemble a suspicious executable file to determine if it contains malware. By converting machine code back into a more readable form, it allows analysts to explore and analyze code that isn't accompanied by source files.
