FAQPage Schema
How do I identify high-value fuzz targets in a codebase?

To identify high-value fuzz targets, analyze function boundaries, input surfaces, and potential failure points within the codebase. This process ranks important functions and parsing logic to guide fuzzing priorities and produce a shortlist of actionable targets.

What is the best way to select functions for fuzzing?

Selecting functions for fuzzing involves analyzing repository structure, tests, and documentation to map inputs, outputs, and edge cases. This yields a prioritized FUT shortlist with notes on harnessing and seed corpus decisions.

How do I rank parsing boundaries for fuzzing readiness?

Rank parsing boundaries for fuzzing readiness by summarizing input types, decoding steps, and potential failure points. The workflow evaluates existing test coverage to guide seed corpus decisions and target prioritization.

Can I use this fuzz target discovery workflow for Python projects?

Yes, you can apply this fuzz target discovery workflow to Python projects and other languages. It analyzes the repository structure and existing tests to map inputs and outputs, producing a ranked target list regardless of language.

Does code analysis for fuzzing require existing tests and documentation?

Code analysis for fuzzing relies on existing tests, repository structure, and documentation to map inputs, outputs, and edge cases. These elements are crucial for accurately ranking important functions and guiding seed corpus decisions.

When should I not use automated function discovery for fuzzing?

Automated function discovery for fuzzing may be less effective when a repository lacks sufficient structure, tests, or documentation to map inputs and outputs. The process depends on these elements to identify boundaries and generate an actionable FUT shortlist.
