Installation

Install release binaries (Without Go Installed)

Visit the releases page and find the appropriate archive for your operating system and architecture. Download the archive from your browser or copy its URL and retrieve it with wget or curl:

• ...with wget:

   wget https://github.com/hueristiq/xurlfind3r/releases/download/v<version>/xurlfind3r-<version>-linux-amd64.tar.gz

• ...or, with curl:

   curl -OL https://github.com/hueristiq/xurlfind3r/releases/download/v<version>/xurlfind3r-<version>-linux-amd64.tar.gz

...then, extract the binary:

tar xf xurlfind3r-<version>-linux-amd64.tar.gz

TIP: The above steps, download and extract, can be combined into a single step with this onliner

curl -sL https://github.com/hueristiq/xurlfind3r/releases/download/v<version>/xurlfind3r-<version>-linux-amd64.tar.gz | tar -xzv

NOTE: On Windows systems, you should be able to double-click the zip archive to extract the xurlfind3r executable.

...move the xurlfind3r binary to somewhere in your PATH. For example, on GNU/Linux and OS X systems:

sudo mv xurlfind3r /usr/local/bin/

NOTE: Windows users can follow How to: Add Tool Locations to the PATH Environment Variable in order to add xurlfind3r to their PATH.

Install source (With Go Installed)

Before you install from source, you need to make sure that Go is installed on your system. You can install Go by following the official instructions for your operating system. For this, we will assume that Go is already installed.

go install ...

go install -v github.com/hueristiq/xurlfind3r/cmd/xurlfind3r@latest

go build ... the development Version

• Clone the repository

   git clone https://github.com/hueristiq/xurlfind3r.git 

• Build the utility

   cd xurlfind3r/cmd/xurlfind3r && \
   go build .

• Move the xurlfind3r binary to somewhere in your PATH. For example, on GNU/Linux and OS X systems:

   sudo mv xurlfind3r /usr/local/bin/

  NOTE: Windows users can follow How to: Add Tool Locations to the PATH Environment Variable in order to add xurlfind3r to their PATH.

NOTE: While the development version is a good way to take a peek at xurlfind3r's latest features before they get released, be aware that it may have bugs. Officially released versions will generally be more stable.

Post Installation

xurlfind3r will work right after installation. However, BeVigil, Github and Intelligence X require API keys to work, URLScan supports API key but not required. The API keys are stored in the $HOME/.hueristiq/xurlfind3r/config.yaml file - created upon first run - and uses the YAML format. Multiple API keys can be specified for each of these source from which one of them will be used.

Example config.yaml:
