Assetfinder

Assetfinder is a subdomain enumeration tool that can be used to find subdomains for a given domain. To install Assetfinder, you need to have a basic understanding of the command line and some experience with using a terminal or command prompt.

Here are the steps to install Assetfinder on a Linux or macOS system:

1. Install Go, if you don't have it already installed:

sudo apt-get install golang-go

2. Set up the GOPATH environment variable:

export GOPATH=$HOME/go

3. Install Assetfinder:

go get -u github.com/tomnomnom/assetfinder

4. Once the installation is complete, you can run Assetfinder from the terminal by typing:

assetfinder

To install Assetfinder on a Windows system, you will need to follow a similar process, but some of the commands and steps may be different.

Once Assetfinder is installed, you can use it to perform subdomain enumeration on a target domain. For example, to enumerate subdomains for the domain "example.com", you can run the following command:

assetfinder example.com

This will enumerate subdomains for the domain "example.com" using the sources specified in the tool's configuration file.

You can also combine the results of Assetfinder with other subdomain enumeration tools to get a more comprehensive list of subdomains. For example, you can pipe the output of Assetfinder into another tool, such as Aquatone, to perform screenshotting and HTML content analysis:

assetfinder example.com | aquatone

These are the basic steps for installing and using Assetfinder for subdomain enumeration. You can find more information on the options available with Assetfinder by running the following command:

assetfinder -h

This will display the help information for the tool, which includes a description of each option and how to use it.
