Curriculum Overview: Detailed Course Breakdown

The "Windows Persistence" course at Boston Cybernetics Institute offers a comprehensive deep dive into the building blocks and advanced components of Windows systems critical for sophisticated Cyber Network Operations (CNO). Over the course of 50 days, participants will engage with a curriculum meticulously designed to elevate their skill set in developing robust and persistent software capabilities. Here’s a closer look at the material we’ll cover:

Build Environment

A robust build environment is the cornerstone of any cyber security-focused development, particularly when crafting persistent systems. In this section, we delve into the specifics of configuring a build environment tailored for the development of cyber security tools. This includes selecting and setting up compilers, debuggers, and other essential tools that are compatible across various versions of Windows. We focus on creating environments that can build both kernel and user-mode utilities, which are often the backbone of persistent mechanisms in CNO operations.

Windows Foundations

Understanding the bedrock of Windows OS is crucial for cyber security professionals aiming to develop or mitigate persistent threats. We provide an extensive overview of Windows internals, including the kernel, system services, the Windows API, and the subsystems that support the OS's graphical user interface. This knowledge is essential for identifying potential security vulnerabilities that can be used for or against persistence mechanisms.

Objects and Handles

In Windows, objects and handles are central to resource management. This section covers how security descriptors and access controls are applied to these objects, imparting an understanding of how to securely manage handles while avoiding leaks that could be exploited by malicious entities to gain persistence or escalate privileges.


Processes are fundamental to the operation of Windows systems. We explore process creation, management, security contexts, and how processes can be manipulated to maintain persistence on a compromised system. Cyber security implications, such as process hollowing and injection techniques, are studied in detail.


Threads are the smallest sequence of programmed instructions that can be managed independently by the scheduler. This module covers thread synchronization, concurrency, and the implications of thread safety in the context of cyber security. We examine how threads can be exploited to execute code within other processes, aiding in the development of stealthy, persistent payloads.

Synchronization Objects

Correct synchronization of concurrent operations is pivotal to maintain system stability and security. We dissect various synchronization primitives offered by Windows, such as mutexes, semaphores, and events, and their role in preventing race conditions and deadlocks, which are often exploited in cyber attacks.

File and Device I/O

File systems and device I/O operations are potential targets for persistent threats. This section covers secure file operations, the role of file permissions, and how device I/O can be monitored or manipulated by malicious software to gain or maintain access to a system.


Networking is a double-edged sword in cyber security: it allows for communication and data transfer, but also for data exfiltration and command and control (C2) operations. Our course covers network stack intricacies, protocol security, and the development of covert channels to evade network defenses.

Memory Management

Robust memory management is key to preventing software vulnerabilities. We look at Windows memory architecture, how memory can be allocated and managed securely, and how mismanagement can lead to security vulnerabilities like buffer overflows, which can be exploited for persistent access.

Libraries (DLL / Static)

Understanding how to properly utilize dynamic and static libraries is essential in CNO tool development. We discuss secure library use, the implications of side-loading vulnerabilities, and how libraries can be a vector for persistent threats.


Windows security features are both an obstacle and an asset in cyber operations. We dissect features like User Account Control (UAC), security tokens, and Windows Defender, teaching students how these can be navigated or leveraged to maintain operational security and persistence.


The Windows Registry acts as the database for the system configuration. We explore how the registry can be safely manipulated for legitimate purposes, and how it can be used by attackers to achieve persistence by running malware at system startup.

Interprocess Communication (IPC) Mechanisms

IPC is crucial for the coordination between processes running on the same machine. This section covers the various IPC mechanisms in Windows, such as pipes and shared memory, and how they can be secured or exploited by cyber threats to maintain persistence.


Windows services run in the background and are often used by software to perform routine tasks. We discuss how services can be created and managed securely, and how malicious services can be used for persistence and privilege escalation.

Component Object Model (COM)

COM is a binary-interface standard for software components. This module covers how COM can be used to extend the functionality of applications and how it can be exploited for persistent access by cyber adversaries.

Crypto Next Generation (CNG) / Bcrypt

Cryptography is essential in securing data and communications. We go over the CNG API in Windows, discussing secure cryptographic practices and how weaknesses in cryptographic implementations can be exploited.

.NET and .NET Framework

The .NET Framework is a popular target for attackers due to its widespread use. We cover secure coding practices in .NET, common vulnerabilities, and how the .NET runtime can be used to create persistent mechanisms in CNO operations.


Debugging skills are vital for both developing secure software and analyzing potential security threats. This section emphasizes the importance of debugging in the cyber security domain, including techniques for reverse engineering and understanding malware operations.

Each of these topics will be examined through the lens of cyber security, with an emphasis on developing a comprehensive understanding of how each can be used to create secure systems, as well as how they can be exploited for persistent access. The course material is designed not just to impart knowledge, but to apply it in practical, hands-on scenarios that reflect real-world cyber security challenges.
