The Open Web Application Security Project (OWASP) Amass project was originally created when the project lead was showing organizations what they look like on the Internet. During this process, he noticed that the tools available were returning incomplete results relative to what could be discovered manually. With the identification of this gap in capabilities for security experts, the Amass project was born. The OWASP Amass project is focused on DNS enumeration and automated network infrastructure mapping techniques. This presentation will discuss a variety of the techniques utilized by Amass.
