Fierce Domain Scan


Fierce domain scanner

Fierce Domain Scan was born out of a frustration while performing a web application security audit. It used to be very time-consuming to discover large swaths of a non-contiguous corporate network, but it doesn't have to be. It's terribly easy to run a scanner against an IP range, but if a network's web presence is distributed across multiple ranges, you can miss huge chunks of networks. Fierce helps solve that problem.

Fierce is a reconnaissance tool written in Perl that quickly scans domains (usually in just a few minutes, assuming no network lag) using a variety of techniques to locate undocumented, internal or just hard-to-find resources via the DNS system.
