And the various options required for the testing :D

Installation

Homebrew (macOS/Linux)

brew install dalfox

# https://formulae.brew.sh/formula/dalfox

Snapcraft (Ubuntu)

sudo snap install dalfox

Arch Linux (AUR)

yay -S dalfox
# or
paru -S dalfox

Chocolatey (Windows)

choco install dalfox

See the Installation guide for manual build instructions.

Nixpkgs (NixOS)

A package is available for Nix or NixOS users. Keep in mind that the latest releases might only be present in the unstable channel.

nix-shell -p dalfox

Nix Flakes

For Nix users with flakes enabled:

# Run directly
nix run github:hahwul/dalfox -- scan https://example.com

# Install
nix profile install github:hahwul/dalfox

# Development environment for hacking on Dalfox itself
git clone https://github.com/hahwul/dalfox && cd dalfox && nix develop

The flake also exposes overlays.default, so NixOS and home-manager users can build Dalfox against their own nixpkgs. See the Installation guide for that module snippet and the rest of the details.

Prebuilt binaries (including statically-linked musl variants for Linux) are available on the GitHub Releases page.

Usage

dalfox [mode] [target] [flags]

Single URL: dalfox scan http://example.com -b https://callback
File Mode: dalfox scan urls.txt --custom-payload mypayloads.txt
Pipeline: cat urls.txt | dalfox scan --headers "AuthToken: xxx"
Custom injection point (query): dalfox scan 'https://example.com/?q=FUZZ&page=1' --inject-marker FUZZ
Custom injection point (header): dalfox scan https://example.com -H 'X-Search: FUZZ' --inject-marker FUZZ

Check the CLI reference and Quick start documents for more examples.

V2

Looking for the Go (v2.x) version? Dalfox v3 is a complete rewrite in Rust. The Go codebase is preserved on the v2 branch and continues to receive security backports. See SECURITY.md for the support policy, and the migration guide for what changed in v3.
