Ghidra

Ghidra (pronounced gee-druh;[3] /ˈɡiːdrə/[4]) is a free and open source reverse engineering tool developed by the National Security Agency (NSA) of the United States. The binaries were released at RSA Conference in March 2019; the sources were published one month later on GitHub.[5] Ghidra is seen by many security researchers as a competitor to IDA Pro.[6] The software is written in Java using the Swing framework for the GUI. The decompiler component is written in C++, and is therefore usable in a stand-alone form.[7]

Scripts to perform automated analysis with Ghidra can be written in Java or Python (via Jython),[8][9] though this feature is extensible and support for other programming languages is available via community plugins.[10] Plugins adding new features to Ghidra itself can be developed using a Java-based extension framework.[11]

History

Ghidra's existence was originally revealed to the public via WikiLeaks in March 2017,[12] but the software itself remained unavailable until its declassification and official release two years later.[5]

In June 2019, Coreboot began to use Ghidra for its reverse engineering efforts on firmware-specific problems following the open source release of the Ghidra software suite.[13]

Ghidra can be used, officially,[14][15] as a debugger since Ghidra 10.0. Ghidra's debugger supports debugging user-mode Windows programs via WinDbg, and Linux programs via GDB.[16]

Supported architectures

The following architectures or binary formats are supported:[17]
