Advisory Infrastructure Setup Scripts

About

Have you ever been bothered with setting up your C2 infrastructure on AWS prior to/during a red team engagement? Having to deal with logging in, configuring security groups, going through the process of creating DNS record sets and such?

If you hate doing this time after time and just wanna have a script that does everything for you - you've come to the right place.

AWS Kommandos automates the process of creating cloud instances for various purposes - as C2 servers, for example. It also helps you to manage your AWS console - from changing firewall rules and managing your SSH access keys to adjusting the DNS record sets. All in one damn script.

You're only expected to create an AWS account and configure the access keys for running Kommandos locally.

See the Usage section for getting an idea how to use it.

Kommandos automatically creates its directory under the ~/.aws-kommandos path to store SSH private keys it creates.

Installation

Install the toolset

apt install python3 python3-pip
pip3 install aws-kommandos

Configure the AWS credentials

The first option is to use the awscli client to configure your AWS credentials used by Kommandos. aws configure

The second options is to export the AWS credentials as environment variables

export AWS_ACCESS_KEY_ID=key_id
export AWS_ACCESS_KEY_SECRET=secret
export AWS_REGION=region

The third option is to use the command-line arguments to pass credentials to Kommandos aws-kommandos --access-key-id <key_id> --access-key-secret <secret> --region-name <region>

Usage

Print Kommandos options

aws-kommandos --help

aws-kommandos -h

Print AWS stats (instances, security groups, ssh keys, DNS hosted zones)

aws-kommandos --stats

Print detailed AWS stats

aws-kommandos --stats --verbose

aws-kommandos --stats -v

Terminate all running EC2 instances

Oh, and did I mention that if you don't have an SSH access key the script automatically creates one for you? Use --force-recreate-key to force the script into creating a new key even if one with the same name exists.

Start a new instance and autoconfigure the DNS record sets

This command starts a new instance and uses the domain name supplied with the --fqdn argument to create A and MX record sets pointing to the IP address of the newly created EC2 instance.
