I am working on reversing a closed source project that uses a well known open source framework.

I am thinking that theoretically, by diffing the program and the framework, I should at least get a few matches that could aid me in cleaning up and understanding more of what I'm doing.

Is there something that does this for me?

If you have the exact copy of the open-source library binary used in the project (the .a or .lib file), you can use Flair to generate FLIRT signatures for it and then load and apply these signatures in your closed-source IDA project.

  • I do not, I have only the source code. I'm also expecting that the source code of this library will be slightly altered in some points, so I'd want to import only whatever matches completely. Commented Mar 29, 2019 at 14:16
