ziggy

ziggy is a fuzzer manager for Rust projects which is built to:

• launch different fuzzers in parallel with a shared corpus
• create and monitor continuous fuzzing pipelines

Feature set

• 🤹 handling of different fuzzing processes in parallel (honggfuzz, AFL++)
• 🗃️ one shared corpus for all fuzzers
• 🤏 regular corpus minimization
• 📊 insightful monitoring
• 🎯 easy coverage report generation
• 😶‍🌫️ Arbitrary trait support

Features will also include:

• 🐇 LibAFL integration
• 📨 notification of new crashes via a simple email hook (limited to 1/day to avoid spamming)
• ⬇️ auto-pull of latest target project version

Usage example

First, install ziggy and its dependencies by running:

cargo install ziggy afl honggfuzz grcov

Here is the output of the tool's help:

``` $ cargo ziggy A multi-fuzzer management utility for all of your Rust fuzzing needs 🧑‍🎤

Usage: cargo ziggy

Commands: build Build the fuzzer and the runner binaries fuzz Fuzz targets using different fuzzers in parallel run Run a specific input or a directory of inputs to analyze backtrace minimize Minimize the input corpus using the given fuzzing target cover Generate code coverage information using the existing corpus plot Plot AFL++ data using afl-plot help Print this message or the help of the given subcommand(s)

Options: -h, --help Print help information -V, --version Print version information ```

For an example fuzz project, see the url example.

Note about coverage

The cargo cover command will assume two things if you run it without any arguments: - you are working somewhere within your $HOME directory - your $CARGO_HOME is also somewhere within your $HOME directory

If one of these assumptions is incorrect, you can use the following workaround: CARGO_HOME=$PROJECT_DIR/.cargo cargo ziggy cover --source $PROJECT_DIR

where $PROJECT_DIR encapsulates all of the code that you want the fuzzer to cover.
