A Go-based crash analysis tool that processes and reproduces crash files from fuzzing tools like AFL with multiple debugging engines and output formats.
Checked October 2026.
Crashwalk is a Go-based tool designed for analyzing crash files generated by fuzzing tools like AFL (American Fuzzy Lop). The tool consists of both a Go library and a standalone command-line utility called cwtriage.
The cwtriage component runs crash files with instrumentation to reproduce crashes and analyze their characteristics. It supports multiple debugging engines including GDB and LLDB for crash analysis. The tool can process crash files from AFL directories and provides pattern matching capabilities to filter specific files or directories.
Key features include configurable timeout and memory limits for target processes, multiple output formats (JSON, Protocol Buffers, text), and database integration using BoltDB to track previously analyzed crashes. The tool can run continuously at specified intervals and includes options for strict mode operation that aborts if crashes fail to reproduce.
Crashwalk integrates with fuzzing workflows by automatically processing crash files and generating detailed reports about crash reproducibility and characteristics. It supports template-based crash file handling and can move processed crashes for organization purposes.
