      Interesting thread about a reverse engineering IDA-like tool the NSA are apparently planning to open source soon. Fingers crossed this shakes up the RE ecosystem 🤞🏻https://www.reddit.com/r/ReverseEngineering/comments/ace2m3/come_get_your_free_nsa_reverse_engineering_tool/ed7trl2/ …

      Doesn’t seem to be groundbreaking. Probably why they feel comfortable releasing it.

      Even 50% feature parity with IDA and not being IDA would be fantastic and sorely sorely needed imho.

      I don’t think that is a fair criticism of the ecosystem; Binary Ninja, and probably others, is closer to feature parity than that.

      Umm, not even close. They're as far apart as MS Paint and Photoshop.

      A few months ago when Hex Rays stopped selling named licenses. I'd really like to switch and encourage competition, and would be willing to give up a lot of features - but the feature parity is not close enough for my use case.

      Just right off the top, I could live without a decompiler.... but that sure is a big nice-to-have that speeds up my work. Apparently GHIDRA has one, even if it's not great, that sure sounds like a good start.. and being open source at least I could hack it. 🤷‍♂️

          If you're willing to spend a few minutes on it I'd love to hear more about which features were missing that you needed. Best case, some of them are there just not exposed/documented well enough. Worst case, we can make sure they're on our todo list if not already.

          And yeah, decompiler is definitely on the todo list of course but still a ways out. MLIL view with types is much closer than assembly, but not the same as a true decompiler. Current short term priorities are more on UI/workflow improvements.
