    Directory/File, DNS and VHost busting tool written in Go

Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). ...
