The target server as described below is running a DNS server. DNS zone transfer is enabled on the server. You have to interact with this DNS server and answer the following questions:

Note: Please make sure to specify the target DNS server (192.X.Y.3) while making the DNS queries/requests. This server is NOT configured in the attacker machine. Hence, we need to specify it explicitly. 

Questions:

  1. How many A Records are present for witrap.com and its subdomains?
  2. What is the IP address of machine which support LDAP over TCP on witrap.com?
  3. Can you find the secret flag in TXT record of a subdomain of witrap.com?
  4. What is the subdomain for which only reverse dns entry exists for witrap.com? witrap owns the ip address range: 192.168.*.*
  5. How many records are present in reverse zone for witrap.com (excluding SOA)? witrap owns the ip address range: 192.168.*.*

Instructions: 

  • This lab is dedicated to you! No other users are on this network :) 
  • Once you start the lab, you will have access to a root terminal of a Kali instance
  • Your Kali has an interface with IP address 192.X.Y.Z. Run "ip addr" to know the values of X and Y.
  • The target server should be located at the IP address 192.X.Y.3. 
  • Do not attack the gateway located at IP address 192.X.Y.1 
  • postgresql is not running by default so Metasploit may give you an error about this when starting


Verify:
1. Secret flag in TXT record of a subdomain of witrap.com:
 
2. How many records are present in reverse zone for witrap.com (excluding SOA)? witrap owns the ip address range: 192.168.*.*
