nationalsecurityagency/ghidra is a software reverse engineering (software reverse engineering, SRE) framework that breaks compiled code apart to read its internal structure. It is a project created and maintained by the National Security Agency Research Directorate, and the latest release published in the repository is Ghidra_12.1.4_build. The given materials do not cover what this release added or fixed. Here we deal only with the repository description and the feature scope listed in the README.
Reverse engineering is the work of taking an executable apart to find out how a program works. The README states that Ghidra analyzes compiled code on Windows, macOS, and Linux, and offers disassembly, assembly, decompilation, graphing, and scripting features. It is a practical reverse engineering tool that handles multiple instruction sets and executable formats, and supports both interactive operation and automation modes. Extension components and scripts can be written in Java or Python. The primary language is Java, the license is Apache-2.0, and the repository has 92396 stars. The repository was created on March 1, 2019.
However, the change list and the performance figures for Ghidra_12.1.4_build are not in the given materials. The only filled-in score is momentum 10.0 (out of 10), and the technical and quality scores have no values. A single score cannot be used to gauge a tool's performance or analytical depth. What these materials confirm is only the scope — a reverse engineering tool dealing with multiple instruction sets and executable formats — and the basic facts about the repository. Until we know what the version improved, it is hard to reach a judgment based on this release.
