Subscraper – Tool That Performs Subdomain Enumeration Through Various Techniques

SubScraper uses DNS brute force, Google & Bing scraping, and Virus Total to enumerate subdomains without an API. 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.
