Originally written to enumerate Azure cloud domains, although the domains and permutations arguments could be applied to any dns enumeration.

Based on MicroBurst from NetSPI - https://github.com/netspi/microburst Swiped the permutations.txt and the list of subdomains from there.

Wrote my own because the ps1 file was super slow in my Windows VM and it's quicker for me to write python than to understand powershell.

(.env) danny@Dannys-MBP subdomain_enum % python ./subdomain_enum.py -h
usage: subdomain_enum.py [-h] [--base BASE] [--permutations PERMUTATIONS] [--domains DOMAINS] [--outfile OUTFILE]

Enumerate Azure Cloud resources

optional arguments:
  -h, --help            show this help message and exit
  --base BASE           Base word
  --permutations PERMUTATIONS
                        File containing permutations
  --domains DOMAINS     File containing domains
  --outfile OUTFILE     Output file

  (.env) danny@Dannys-MBP subdomain_enum % python ./subdomain_enum.py --base test --outfile out.txt
