NSBrute is a Python utility designed to identify and exploit domains vulnerable to AWS NS (Name Server) takeover attacks. The tool automates the process of discovering misconfigured DNS settings where domain name servers point to AWS resources that are no longer active or properly configured. This creates an opportunity for attackers to register the abandoned AWS resources and gain control over the domain's DNS resolution. NSBrute operates by scanning target domains and checking for vulnerable NS configurations that could allow unauthorized takeover of DNS control. The utility focuses specifically on AWS-hosted name servers that may have been decommissioned or improperly configured, leaving domains susceptible to subdomain takeover attacks. The tool is implemented in Python and provides functionality for security researchers and penetration testers to assess domain configurations for potential NS takeover vulnerabilities in AWS environments.
