SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Fuzzing dictionaries provide domain-specific tokens and payloads to steer mutation-based fuzzers toward deeper, meaningful code paths, reducing random exploration and increasing coverage of edge cases.

Core Features & Use Cases

  • Generates dictionaries containing quoted strings, magic bytes, protocol keywords, and format-specific tokens for libFuzzer (-dict=), AFL++ (-x), and cargo-fuzz.
  • Derives dictionary content from headers, binary strings, man pages, and LLM prompts to broaden surface area and improve failure discovery.
  • Applies to fuzzing parsers (JSON, XML, config), protocol handlers (HTTP, DNS), and file format processors (PNG, PDF, media codecs) to reveal subtle vulnerabilities and robustness issues.

Quick Start

Create a dictionary file of tokens and hex-escaped values and pass it to your fuzzer with the appropriate -dict or -x option to start guided mutation.

FAQPage Schema
How do I create a fuzzing dictionary for parsing protocols like HTTP or DNS?▼

Fuzzing dictionaries reduce random exploration by providing domain-specific tokens and payloads to mutation-based fuzzers. This targeted approach increases coverage of edge cases and steers fuzzers toward meaningful code paths in parsers and file format processors.

How do I use a fuzzing dictionary with libFuzzer or AFL++?▼

Deriving dictionary content from headers, binary strings, man pages, and LLM prompts broadens the attack surface area. Extracting format-specific tokens and quoted strings from these sources improves failure discovery during fuzzing.

Can I use a single fuzzing dictionary across different fuzzing tools?▼

Dictionaries apply to fuzzing parsers like JSON and XML, protocol handlers like HTTP and DNS, and file format processors like PNG and PDF. They provide format-specific tokens and magic bytes to reveal subtle robustness issues.

What is the best way to improve fuzzer coverage for file format processors?▼

You can start guided mutation by creating a dictionary file of tokens and hex-escaped values. Pass this file to your fuzzer using the appropriate -dict or -x option to begin testing parsers, protocols, or file formats.
