This week I got even more familiar with awk. Using Regular expression with awk can be very powerful for parsing command outputs. I also learned how to do DNS enumeration. I see how this can be a very powerful tool for reconnaissance. Organizations will most likley have most of thier servers if not all of them in DNS. Using DNS enumeration you can easily map our a companies infrastructure.

This week I made three scripts dealing with DNS. One is writen in PowerShell the other two were in Bash. The scripts can be seen below.

• dns-resolver.ps1
• dns-resolver.sh
• portscanner2.sh

Git

git clone
git pull
git add *
git commit -m "Message"
git push

DNS Commands

dig axfr @dns-server domain.name
nslookup <IP address> <dns server>
Resolve-DnsName -DnsOnly <IP address> -Server <dns server>
sudo nmap -sL <IP range in cider notation> --dns-servers <dns server>
