Ghidra: A software reverse engineering suite of tools developed by the NSA
It is open source software and it can reverse engineer programs from a lot of different systems.<p>Some people may be worried about installing a piece of software on their computer that comes from the NSA. I don't think that there are real reasons to worry. One of the tasks of the NSA is defending against cyber attacks. Having more people with good tools helps the defense. Also, you can be pretty certain that some security people have been closely looking at the sources to see if it contains any suspicious features. Besides, if the NSA really wants to install some software on your computer, they can probably do it themselves without your involvement.
