Get (rid of) Wildcard Domains

go get github.com/thelikes/gwdomains

This tool takes a list of potential sub domains and filters out only legitimate domains. For use with tools like altdns, dnsgen, and syborg.

1. Brute force sub domains (knock,amass,fierce,subfinder,etc)
2. Run a mutator (dnsgen,syborg,etc)
3. Resolve the mutations
4. Feed gwdomains the mutated sub domains

cat mutated.txt | gwdomains

Verbose output:

cat mutated.txt |MYGODEBUG=true gwdomains
