ASNRECON

A tool to perform reconaissance using autonomous system number (ASN) lookups combined with SSL cert scanning 📡

Usage

usage: python asnrecon.py

Select an option:
	[1] Full ASN scan
	[2] Specific IPv4 range scan

• Full ASN scan

Using this option, the script will take a single domain/hostname which it will then perform a lookup against the local ASN database and select a list of IP ranges associated with that ASN.

Note: The script can take an input file main.config which can be used to prevent scanning specific IP ranges. IP addresses to be avoided should be supplied in a comma delimited format.

• Specific IPv4 range scan

This option accepts an IP address range 0.0.0.0/0 and attempt to perform SSL connections while printing any identified certs
