HostileSubBruteforcer - Pure Subdomain Bruteforce.

HostileSubBruteforcer – Pure Subdomain Bruteforce.

This app will bruteforce for exisiting subdomains and provide the following information:
+ IP address
+ Host
+ if the 3rd party host has been properly setup. (for example if site.example.com is poiting to a nonexisiting Heroku subdomain, it’ll alert you) -> Currently only works with AWS, Github, Heroku, shopify, tumblr, blogspot/blogger and squarespace.
There may be some false positives depending on the host configurations.
