AWS Instance Port Scanner

This utility will scan the ports on your AWS instances and report which ports are open to the public.

You will need to ensure you have setup the standard ~/.aws/credentials and ~/.aws/config per the instructions here.

You will also need to install the boto3 python module. This module is included in many distribution repositories or can be installed using pip:

    $ sudo pip3 install boto3

Usage

usage: aws_scanner.py [-h] [-r [REGION_PREFIXES [REGION_PREFIXES ...]]]
                      [-s START_PORT] [-e END_PORT] [-j JOBS] [-t TIMEOUT]

Scan AWS instances for open ports

optional arguments:
  -h, --help            show this help message and exit
  -r [REGION_PREFIXES [REGION_PREFIXES ...]], --region-prefixes [REGION_PREFIXES [REGION_PREFIXES ...]]

                        Timeout in seconds waiting for port to answer
                        (default: 5)
