This repository is a comprehensive OSCP pentesting cheatsheet composed of markdown notes and diagrams. It serves as a reference guide for penetration testing methodologies, covering enumeration, privilege escalation, web application testing, Active Directory attacks, and more. While not containing executable code or data processing pipelines, it curates actionable information from various security resources into an organized format. The content is structured as checklists and step-by-step guides for common pentesting tasks, making it immediately applicable for individuals preparing for the OSCP certification or conducting real-world assessments. The repository does not ingest or transform external datasets; instead, it represents synthesized knowledge intended for direct consumption. Despite lacking traditional data engineering components, the repository demonstrates value as a knowledge artifact. Its maintenance is active with recent updates, and the static nature ensures zero technical drift. Reproducibility is trivial as the entire content is self-contained within the repository.
