The purpouse of this tool is helping bug hunters and pentesters during reconnaissance

If you want to know more about the tool you can read my own post in my blog (written in spanish)


It can be used in any system with python3

You can easily install AORT using pip:

:ballot_box_with_check: Domain Zone transfer attack

:ballot_box_with_check: WAF type detection

:ballot_box_with_check: Subdomain Takeover checker

:ballot_box_with_check: Scan common ports

Simple query to find valid subdomains

Third part

The tool uses different services to get subdomains in different ways

The WAF detector was modified and addapted from CRLFSuite concept

All DNS queries are scripted in python at 100%

Email harvesting using Proxycrawl API with personal token (you can register a free account with 100 uses)
