Why this tool?
Altdns is a security tool to discover subdomains. It generates permutations, alterations, and mutations of subdomains. The generated names can also be tested by performing DNS lookups. An enumeration tool like Altdns is useful during penetrating testing assignments.
How it works
Altdns works with two lists to generate the subdomains. The first one is a list of known subdomains. The second list includes possible words that might be used as a subdomain (e.g. testing, status, backup). The resolving of the generated names can be done using the -r option.
Background information
During our review, we noticed that the tool only works with Python 2.
Usage and audience
altdns is commonly used for reconnaissance, subdomain discovery, or subdomain enumeration. Target users for this tool are pentesters and security professionals.
