ansible-role-cobalt-strike

An Ansible role for installing Cobalt Strike.

Pre-requisites

In order to execute the Molecule tests for this Ansible role in GitHub Actions, a build user must exist in AWS. The accompanying Terraform code will create the user with the appropriate name and permissions. This only needs to be run once per project, per AWS account. This user can also be used to run the Molecule tests on your local machine.

Before the build user can be created, you will need a profile in your AWS credentials file that allows you to read and write your remote Terraform state. (You almost certainly do not want to use local Terraform state for this long-lived build user.) If the build user is to be created in the CISA COOL environment, for example, then you will need the cool-terraform-backend profile.

The easiest way to set up the Terraform remote state profile is to make use of our aws-profile-sync utility. Follow the usage instructions in that repository before continuing with the next steps, and note that you will need to know where your team stores their remote profile data in order to use aws-profile-sync.

To create the build user, follow these instructions:

cd terraform
terraform init --upgrade=true
terraform apply

Once the user is created you will need to update the repository's secrets with the new encrypted environment variables. This should be done using the terraform-to-secrets tool available in the development guide. Instructions for how to use this tool can be found in the "Terraform IAM Credentials to GitHub Secrets" section. of the Project Setup README.

If you have appropriate permissions for the repository you can view existing secrets on the appropriate page in the repository's settings.
