SubScraper

SubScraper uses DNS brute force, Google & Bing scraping, and DNSdumpster to enumerate subdomains of a given host. Written in Python3, SubScraper performs HTTP(S) requests and DNS "A" record lookups during the enumeration process to validate discovered subdomains. This provides further information to help prioritize targets and aid in potential next steps. Post-Enumeration, "CNAME" lookups are displayed to identify subdomain takeover opportunities.

Users also have the option of adding their Censys.io API Key & Secret in the command line arguments. This will allow subdomain enumeration using the Censys.io SSL Cert database. Create an account to get a free API key here: https://censys.io/register.
