Atomic Operator

atomic-operator can be used on the command line or via your own scripts. This page shows how the options available within atomic-operator.

Command Line

You can access the general help for atomic-operator by simplying typing the following in your shell.

atomic-operator

Retrieving Atomic Tests

In order to use atomic-operator you must have one or more atomic-red-team tests (Atomics) on your local system. atomic-operator provides you with the ability to download the Atomic Red Team repository. You can do so by running the following at the command line:

atomic-operator get_atomics 
# You can specify the destination directory by using the --destination flag
atomic-operator get_atomics --destination "/tmp/some_directory"

Running Tests

In order to run a test you must provide some additional properties (and options if desired). The main method to run tests is named run.

# This will run ALL tests compatiable with your local operating system
atomic-operator run --atomics-path "/tmp/some_directory/redcanaryco-atomic-red-team-3700624"

The run command has several mandatory and optional parameters that can be used. You can see these by running the help for this command:

atomic-operator run --help

It will return the following:

NAME
    atomic-operator run - The main method in which we run Atomic Red Team tests.

SYNOPSIS
    atomic-operator run <flags>

DESCRIPTION
    config_file definition:
        atomic-operator's run method can be supplied with a path to a configuration file (config_file) which defines 
        specific tests and/or values for input parameters to facilitate automation of said tests.
        An example of this config_file can be seen below:

            inventory:
              windows1:
                executor: powershell # or cmd
                input:
                  username: username
                  password: some_passowrd!
                  verify_ssl: false
                hosts:

                  # etc
              linux1:

Running atomic-operator using a config_file

In addition to the ability to pass in parameters with atomic-operator you can also pass in a path to a config_file that contains all the atomic tests and their potential inputs. You can find more information about the Configuration File here

Package

In additional to using atomic-operator on the command line you can import it into your own scripts/code and build further automation as needed.

from atomic_operator import AtomicOperator

operator = AtomicOperator()

# This will download a local copy of the atomic-red-team repository

print(operator.get_atomics('/tmp/some_directory'))

# this will run tests on your local system
operator.run(
    technique: str='All', 
    test_guids: list=[],
    atomics_path=os.getcwd(), 
    check_dependencies=False, 
    get_prereqs=False, 
    cleanup=False, 
    command_timeout=20, 
    debug=False,
    prompt_for_input_args=False,
    config_file="some_path.yaml"
    **kwargs
)
