Workflow A Binary Ninja Workflow is an abstraction of a computational binary analysis pipeline and it provides the extensibility mechanism needed for tailored binary analysis and decompilation. More specifically, a Workflow is a repository of activities along with a unique strategy to execute them. Binary Ninja provides two Workflows named core.module.defaultAnalysis and core.function.defaultAnalysis which expose the core analysis.

A Workflow starts in the unregistered state from either creating a new empty Workflow, or cloning an existing Workflow. While unregistered it’s possible to add and remove activities, as well as change the execution strategy. In order to use the Workflow on a binary it must be registered. Once registered the Workflow is immutable and available for use.

Currently, Workflows is disabled by default and can be enabled via Settings:

>>> Settings().set_bool('workflows.enable', True)

Retrieve the default Workflow by creating a Workflow object:

>>> Workflow()
<Workflow: core.module.defaultAnalysis>

Retrieve any registered Workflow by name:

>>> list(Workflow)
[<Workflow: core.function.defaultAnalysis>, <Workflow: core.module.defaultAnalysis>]
>>> Workflow('core.module.defaultAnalysis')
<Workflow: core.module.defaultAnalysis>
>>> Workflow('core.function.defaultAnalysis')
<Workflow: core.function.defaultAnalysis>

Create a new Workflow, show it in the UI, modify and then register it. Try it via Open with Options and selecting the new Workflow:

>>> pwf = Workflow().clone("PythonLogWarnWorkflow")
>>> pwf.show_topology()
>>> pwf.register_activity(Activity("PythonLogWarn", action=lambda analysis_context: log_warn("PythonLogWarn Called!")))
>>> pwf.insert("core.function.basicBlockAnalysis", ["PythonLogWarn"])
>>> pwf.register()
