ÜberDig - dig on steroids

Simple GoLang tool for domain recon.

The purpose of this tool is to provide fast overview of a target domain setup. Several active scanning techniques are employed for this purpose like DNS ping-pong, TLS certificate scraping, WHOIS banner parsing and more. Some tools on the other hand are not - intentionally (e.g. nmap, brute-force, search engines etc.). This is not a full-blown DNS enumerator, but rather something more unobtrusive and fast which can be deployed in long-term experiments with lots of targets.

Feature set:

• Resolves a given domain to all DNS records of interest
• Resolves a given domain to a set of WHOIS contacts (selected properties only)
• Resolves a given domain to a TLS certificate chain
• Supports automatic NS discovery with custom override
• Dissects domains from resolutions and resolves them recursively
• Unobtrusive human-readable CLI output as well as machine readable JSON
• Supports multiple domains on the input
• Colorized output
• Parses domains in HTTP headers
• Parses domains in Certificate Transparency logs
• Parses IPs found in SPF record
• Looks up BGP AS for each discovered IP
• Looks up GeoIP record for each discovered IP
• Attempts to detect DNS wildcards
• Supports graph output
