domain (setup script for Recon-ng and altdns)

subdomain enumeration

Domain is a Python script written by Jason Haddix to combine the tools Recon-ng and altdns. It allows to use the two tool one multiple domains within the same session.

RTA (vulnerability scanner)

information gathering, penetration testing, security assessment, system enumeration

RTA is helpful to automate scanning public resources of a company. As the project name implies, this may be used during red teaming, like a penetration test. That obviously does not limit its use, as it is similarly useful by the blue team.

With its integration with Nessus and other tools, RTA is more of a toolkit. This can be seen in its functionality, like subdomain enumeration and information gathering capabilities.

SubFinder (subdomain scanner)

discovery of sensitive information, information gathering, penetration testing, reconnaissance, security assessment

SubFinder is a tool to scan domains and discover subdomains. This may be useful during the reconnaissance phase of penetration testing where information is collected. Some subdomains may reveal sensitive data or point to interesting targets such as a backup location.

Sublist3r (subdomains enumeration tool)

Sublist3r helps penetration testers and bug hunters collect and gather subdomains for the domain they are targeting.
