Welcome to the cyber-challenger wiki!

This project is written in python and Flask.

The core of the project is a series of modules that are chained together to generate logs that can correlated. That is, events and timing in one log source are consistent and verifiable in other log sources.

How Modules are structured

Each modules consists of a data model + controllers that leverage the data model to generate activity.

Example organization module:

├── email.py
└── email_controller.py

In this example, email.py contains the data model -> class Email:

email_controller.py contains functions that build on the Email class. E.g. gen_inbound_mail():

from app.server.modules.email.email import Email

def gen_inbound_mail(recipient: Employee, actor: Actor, time: float) -> None:
    
    email = Email(
        time=time,
        sender=actor.get_sender_address(),
        recipient=recipient.email_addr,
        subject=actor.get_email_subject(),
        reply_to=reply_to,
        link=link,
        domain=domain,
        actor=actor,
        accepted=random.choices([True, False], weights=(80, 20), k=1)[0],
        authenticity=actor.effectiveness
    )

Curent modules:

Module Name	Description
Clock	Used to compute and manage the "in-game" time. In-game time is an accelerated version of real world time.
Organization	Represents employees who work at the company. Also contains functions used to generate employees
Email	Represents emails sent to and from company employees. Also contains functions for generating email activity.
OutboundBrowsing	Represents web-browsing egressing from the company network. Also contains functions used to generate web-browsing activity.
Endpoint	Represents files and processes running on employee machines. Also contains functions used to generate endpoint activity.
Infrastructure	Represents an internally consistent passiveDNS system (e.g. domain to ip mapping). Also contians functions used to generate dns records.
Logging	Used to send logs to the database in Azure Data Explorer
Trigger	Functions that chain together modules to produce a sequence of events. E.g. Email -> User clicks link -> Filedownload -> C2 beacon
Helpers	Misc helper classes and functions used in the project

How actors are defined

Actors referent to malicious adversaries. These are modeled in a class within the Actors module. However, users can instantiate actors via yaml files in the actor_configs directory
