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.

[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] Ghidra's existence was originally revealed to the public via Vault 7 in March 2017,[12] but the software itself remained unavailable until its declassification and official release two years later.
