sub_sniaX

A tool to do subdomain enumeration using DNS AXFR (zone transfer) and SNI (Server Name Indication) methods.

Features

• DNS AXFR: Attempts DNS zone transfers to find additional subdomains (useful for misconfigured DNS servers).
• CNAME Chaining: Resolves CNAME records and follows chains to discover further subdomains.
• SNI Enumeration: Uses the TLS SNI extension to discover subdomains that are publicly accessible via HTTPS.
• Configurable Delay: Option to add a delay between requests to avoid rate-limiting.

Installation

Ensure that Go is installed and your $GOPATH is set correctly.

go install github.com/noob6t5/sub_sniaX@latest

For a single domain, This is the recommended method.

sub_sniaX -d domain.com -o output.txt -delay 1000

Options

-d: The target domain (e.g., example.com).

-o: Output file where found subdomains will be saved (e.g., output.txt).

-delay: Delay between requests in milliseconds (e.g., 1000 for 1 second).

-f: Input file containing domains, one per line.

Multple Domain : sub_sniaX -f domains.txt -delay 1500

Todo

• Use Stdin Method
• Add more bypasses
• Handle custom input file for SNI from user
