Getting Started

Welcome to Binary Ninja! This introduction document is meant to quickly guide you over some of the most common uses of Binary Ninja. If you're interested in more detailed information, check out the User Guide.

Installing Binary Ninja

The download links you receive after purchasing expire after 72 hours but as long as you have active support you can request download links any time.

Linux

Because Linux install locations can vary widely, we do not assume that Binary Ninja has been installed in any particular folder on Linux. Instead, first unzip the installation zip wherever you wish to install Binary Ninja. Next, for paid versions, run ./binaryninja/scripts/linux-setup.sh. This sets up file associations, icons, and adds Binary Ninja's Python library to your Python path. Adding the library to your path is most helpful for headless functionality in the Commercial and Ultimate editions, but even on the Non-Commercial edition it can help your IDE find the api sources to make plugin development easier. Run the script with -h to see customization options.

macOS

To install on macOS, simply drag-and-drop the app bundle from the DMG to the desired location.

Windows

To install on Windows, use the installer linked from the email you received after purchase. During the install process, you'll need to choose whether to install globally or to your local user path.

License

When you first run Binary Ninja, it will prompt you for your license key. You should have received your license key via the same email that included your download links. If not, please contact support.

Opening Files

While there are more ways than shown here, the most common ways to open a file are:

  • Drag-and-drop
  • File Open
  • Run via CLI

You can change analysis settings by using Open with Options.

UI Basics

Overview ><

By default, you'll see four main areas in Binary Ninja:

  1. Symbol List (one of many sidebar panels)
  2. Cross References
  3. Main View (defaults to High Level IL and can have many panes)
  4. Feature Map

Not enabled by default but can be made visible is the bottom bar which includes the scripting console and log window.

Make sure to check out the many view options available in the various ☰ ("hamburger") menus. Many configuration settings are also available in the Settings menu (hotkey: [CMD/CTRL] ,).

Interacting

command palette ><

One of the most useful features of Binary Ninja is that everything can be quickly and easily accessed through the command palette ([CMD/CTRL] p). You'll be surprised how often it saves you from looking through menus to find out just what you need. Any action in the command palette can be assigned to a custom hotkey. Here are a few of the more useful ones:

  • [ESC] : Navigate backward
  • [SPACE] : Toggle between Linear View and Graph View
  • [F5], [TAB] : Toggle between Pseudo C and Disassembly in the current view
  • g : Go to an address or symbol
  • n : Name a symbol
  • ; : Add a comment
  • i : Cycle between disassembly, LLIL, MLIL and HLIL
  • y : Change type of the currently selected element
  • a : Create a C String at the currently selected address
  • 1, 2, 4, 8 : Change type of a data variable to the indicated width in bytes (creates a variable if none exists)
  • d : Switch between data variables of various widths
  • r : Change the data type to single ASCII character

For more hotkeys, see the User Guide.

Intermediate Languages

Binary Ninja is one of the most advanced binary analysis platforms, and it has a unique stack of related intermediate languages. If that gets you excited, you'll surely want to check out the developer guide for more information. If it doesn't mean anything to you, no worries, here's a few tips to make your life easier. The default view is "High Level IL". It looks and reads almost like pseudo code. There are a few extra annotations that make it more expressive, like how comparisons show whether they are signed or not, and when data is moved the size of the operation is indicated.

Many of the IL behaviors and views are customizable via settings. If you prefer disassembly or even Pseudo C as your default view, no worries, just check out the UI/view.graph and view.linear settings. Likewise, there are several settings available under the "hlil" heading.

Using Plugins

Plugins can be installed by one of two methods, either automatically by using the Plugin Manager, or manually by copying the plugin to the appropriate folder.

Debugger

Binary Ninja includes a debugger that can debug executables on Windows, Linux, and macOS.

For more detailed information, see the debugger guide.

Updates

By default, Binary Ninja is configured to automatically update itself to any new stable releases. However, there are much more frequent updates with fixes and new features available by switching to the Development Branch using the update channel dialog.
