We all know signature scanning can be extremely useful. Sadly, the two public offerings for Binja are either very slow, or crash extremely often.
This is why I wrote this plugin. It's a signature scanning and creating plugin for x86 (more archs are planned!), written in Rust. It's extremely fast, supports multiple signature styles, and works like a charm.
It supports 3 styles of signatures. Or 4, if you want to be specific.
To create a signature, select the instruction you want the signature to point to, then go to Plugins->CSM - Create Signature.
The signature is checked for uniqueness within all executable segments of the binary. .data is not considered, so make sure your signature scanning implementation also ignores non-code sections.
To find a signature, copy the signature to your clipboard in the format you selected in the configuration, and go to Plugins->CSM - Find Signature. All occurrences will be in your log.
These are the settings:
This is how it looks to create a signature, then scan for it:
How to install
- Download the platform-appropriate binary from release section
- Place the binary in your Binary Ninja installation's plugin folder
Once GitHub Actions are set up and a loader plugin has been written, you will be able to install the plugin via the official plugin manager.
Compiling yourself
This project requires the nightly channel of Rust.
Check the blog post above for a step-by-step.
Check the Cargo.toml file and adjust the binaryninja dependency so it points to whatever Binja update channel you want to compile for. !MAKE SURE! Cargo caught your change of branch. It sometimes doesn't realize you changed it. Delete Cargo.lock to make Cargo realize you did. Otherwise, it'll keep using whatever version was selected when you built or rust-analyzer ran.
