Low-Level and OS Foundations for Windows
Trainees cover core low-level programming concepts, operating system internals, and assembly language fundamentals, building the intuition needed to understand how modern CPUs and operating systems execute code and how vulnerabilities like Spectre and Meltdown arise.
Module Overview

Cover the core concepts underpinning low-level programming, including the stack versus the heap, memory layout, endianness, system calls, and execution flow, building the groundwork for reverse engineering and vulnerability research.
Review the internals that matter for security research, including executable formats (PE, ELF), DLLs and shared libraries, kernel architecture, processes, threads and scheduling, virtual memory management, drivers and the boot process, and security mechanisms such as ASLR.
Get introduced to assembly language and calling conventions for x86 and x64 architectures, with hands-on exercises writing and analyzing basic assembly programs.
Develop an intuition for how modern CPUs and operating systems execute code at runtime, and explore the technical foundations behind modern vulnerability classes such as Spectre and Meltdown.
Over 10 Years of Hands-On Expertise.
Effective security testing comes from the combination of the right tools, deep technical knowledge, and the people who know how to apply them. eShard has spent over 10 years developing all three, and our coaching programs put that same expertise directly in your hands.
Frequently Asked Questions
Most courses can be delivered online. Some modules, particularly those involving lab equipment, require onsite presence. Onsite training can be held at eShard's headquarters in Bordeaux, France, or at your own premises. The delivery format can be discussed and agreed upon before the final proposal.
Prerequisites vary by module. Some courses include introductory content for participants new to a topic, while others assume prior knowledge of cryptography or security testing. Each module page indicates the expected background.
Most programs accommodate 3 trainees per coach. Based on our experience, this ratio ensures everyone progresses at the same pace and gets the most out of the session. Contact us to discuss larger groups or custom arrangements.
Yes. Training programs are tailored to each team's technical level and objectives. If your team works on specific targets or protocols, this can be factored into the program before the session begins.
