Sudomy Subdomain analysis

Sudomy is a tool for collecting subdomains and domain analysis with automated recognition. This tool can also be used for OSINT activities.


Active Method

Sudomy uses Gobuster tools due to its high speed in executing DNS Subdomain Bruteforce attack (wildcard support). The word list used comes from SecList Combined Lists (Discover / DNS) containing about 3 million entries

Passive Method

Looks for information through top third-party applications to show you the best results. The information pages are as follows:
