DNS Zone Transfer
About this tool
Check if the name servers of the target domain are vulnerable to DNS Zone Transfer and attempt to retrieve the full DNS Zone file.
DNS servers should not permit zone transfers towards any IP address from the Internet.
Since zone files contain complete information about domain names, subdomains, and IP addresses configured on the target name server, finding this information is useful for increasing your attack surface and for better understanding the internal structure of the target company (ex. find test servers, development servers, hidden domains, internal ip addresses, etc)
Information gathered from zone files can be useful for attackers to implement various attacks against the target company, like targeting test or development servers that are less secure.
Parameters
Target domain name: This is the base domain name for which you want to try zone transfer
How it works
The tool first discovers all the name servers associated with your target domain. Then, to each name server, it sends a Zone Transfer (AXFR) DNS request and sees if it is successful or not. In case of success, the full zone file will be displayed.
