Backtrack 4: Information Gathering: DNS: Dnsrecon – Target enumeration
The next tool I am going to look at is a really great ruby script written by my friend Carlos (Dark operator) Perez. Its called Dnsrecon and is included in Backtrack 4. This is a simple tool written for target enumeration during authorized penetration test engagements. This tool provides different methods for enumerating targets via DNS service.
