Working with Fierce Tool on Kali Linux

Example 1: Basic

fierce --domain w3wiki.org --subdomains write admin videos

In this Example, We are performing a simple scan using the subdomain words which include write, admin, videos. We have chosen w3wiki.org as our target.

Example 2: Traverse IPs near discovered domains to search for contiguous blocks with the –traverse flag

fierce --domain w3wiki.org --subdomains videos --traverse 10

In this Example, We are scanning domains near discovered records. Our target domain is w3wiki.org

Example 3: Attempt an HTTP connection on domains discovered with the –connect flag

fierce --domain stackoverflow.com --subdomains mail --connect

In this Example, We are attempting HTTP connection on the domains using the connect flag. We have chosen a different target for this Example, which is stackoverflow.com.

Example 4: Exchange speed for breadth with the –wide flag, which looks for nearby domains on all IPs of the /24 of a discovered domain

fierce --domain w3wiki.org --wide

In this example, We will scan the entire class of discovered records. (Full Detailed Scan)

Example 5: Zone transfers are rare these days, but they give us the keys to the DNS castle.

fierce --domain w3wiki.org

In this Example, We are performing a basic scan without any arguments on w3wiki.org

Understanding the network structure of the organization is very important. So to locate targets both inside and outside a corporate network there is a tool designed in the Python Language known as Fierce. This tool is different from other tools as its main objective is to locate non-contiguous IP spaces and hostnames against specified domains or subdomains. The Fierce tool doesn’t scan the total internet for our results but the results which it finds are really helpful in the process. This tool is open-source and free to use. The Fierce tool is very easier to use due to its tags of flags features.
