Falcon is a formal binary analysis framework in Rust. Falcon seeks to implement data-flow analysis, abstract interpretation, and constraint solving over compiled, binary executables.
- Expression-based IL with strong influences from Binary Ninja LLIL and RREIL.
- Semantically-equivalent binary translation.
- IL can be translated to smtlib2 (z3) and solved for. Under-pinnings for symbolic execution provided.
- Fixed-point engine for data-flow analysis and abstract interpretation. Basis analyses provided.
- Lifters for Binary formats (initially Elf). This includes run-time linking, assuming dependencies are provided.
- Documentation is available here.
- I am idling in irc.freenode.net#rust-falcon.
- You can also find me in the Binary Ninja slack under the name "endeavor".
Falcon has hit 0.1.0
. This means:
- "Things are working," but, "Everything has not been flushed out."
- Falcon is capable of producing results for toy binaries.
- I am ready for people to open issues, and receive feedback.
There will most likely be some API changes in the next few releases. If you aren't actively developing on Falcon, I recommend you use a tagged released.
As of 1.18, everything, including docs, builds with rust stable.
You will need the correct dependencies for bindgen to build the capstone bindings, as well as z3
on the commandline. The Dockerfile
has everything required to get you set up.
For OSX (on which I'm developing), brew install z3
seems to be enough to make things work, as well as a typical rust install.
