Brief Tour of OFRAK 2.2.1

We published OFRAK 2.2.1 to PyPI on March 8, 2023. As always, a detailed list of changes can be viewed in the OFRAK Changelog. There have been several notable improvements since the first PyPI OFRAK release that are worth highlighting below.

Easy PyPI Install

Getting started with ofrak is now as easy as running: pip install ofrak. This will give you a minimal OFRAK install that includes a handy command-line tool and the OFRAK GUI, in addition to the OFRAK Python library.

To immediately launch the OFRAK GUI and start exploring binaries, run:

				
					% ofrak gui
				
			

The quickest, pure-Python way to start exploring OFRAK’s disassembler backends is to pip install ofrak-angr ofrak-capstone and then use the OFRAK angr backend:

				
					% ofrak gui --backend angr

				
			

(For other backend options, see the Binary Ninja Backend or Ghidra Backend guides.)

Run ofrak --help to explore all of the available commands.

This release also includes some changes that address pip-install issues on Ubuntu and macOS, and adds baseline support for pip-installing OFRAK on Windows. Please continue to upstream these issues to us so that we can continue to improve the OFRAK install experience!

New GUI Features

The latest OFRAK includes the following improvements to the GUI tool:

  • The GUI is now bundled with the ofrak package and can be run with the ofrak gui command
  • Keybindings!
  • A new “Tag” button to allow users to manually tag a resource (See #215)
  • A “jump to offset” feature to quickly move to a specific offset in the GUI’s hexdump/minimap view

New & Updated Components

Support improved or added since OFRAK version 2.0.0:

Performance Improvements

OFRAK 2.1.1 is faster. Here are some highlights:

  • GUI is much faster, especially for resources with hundreds of thousands of children (#191)
  • Remove unneeded and slow .save() when unpacking filesystems (#171)
  • A change to how resources are stored makes deleting (and thus packing) much faster (#201)

As always, we are eager to hear any feedback from OFRAK users! This feedback not only makes us feel warm and fuzzy, it helps prioritize us what we work on next. Feel free to open an issue in the OFRAK GitHub or email us directly at [email protected].
