The National Security Agency (NSA) has open sourced its Ghidra software reverse engineering (SRE) framework. The agency announced the availability of Ghidra 9.0.2 at the annual RSA Security Conference, which wrapped up on Monday, and NSA senior advisor Robert Joyce demo'd it during a conference session.

Written in Java, Ghidra (pronounced GEE-druh) was developed by the NSA's Research Directorate for the agency's cybersecurity mission, and it has been used to support that mission for more than a decade. It was created to "solve scaling and teaming problems on complex SRE efforts," the agency explained, "and to provide a customizable and extensible SRE research platform. NSA has applied Ghidra SRE capabilities to a variety of problems that involve analyzing malicious code and generating deep insights for SRE analysts who seek a better understanding of potential vulnerabilities in networks and systems."
