Knockpy is a python tool designed to enumerate subdomains on a target domain through a wordlist. It is designed to scan for DNS zone transfer and to try to bypass the wildcard DNS record automatically if it is enabled. Now knockpy supports queries to VirusTotal subdomains, you can setting the API_KEY within the config.json file.
