Ghidra

Ghidra (pronounced Gee-druh;[3] /ˈɡiːdrə/[4]) is a free and open source reverse engineering tool developed by the National Security Agency (NSA). 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++. Ghidra plugins can be developed in Java or in Python (provided via Jython).[7]

History

Ghidra's existence was originally revealed to the public via WikiLeaks in March 2017,[8] 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.[9]

Supported architectures

The following architectures or binary formats are supported:[10]

gollark: Oh hey, they're switching to RISC-V?
gollark: MIPS is cool due to being elegant and actually consistent.
gollark: MIPS is truly a great ISA, and an inspiration for PotatoASM™1.
gollark: The browser version is more RAM-efficient, allows "tab" technology for multiple discords at once, and better-sandboxed.
gollark: Imagine using the Discord desktop app. As opposed to the browser version.
