Personal Cybersecurity and CTF Notes Collection Hosted on GitHub

The post shares a collection of personal cybersecurity and hacking notes compiled over several years, now hosted on GitHub after previous files were lost. The notes cover topics including OSINT, reverse engineering, reconnaissance, enumeration, steganography, and terminology, with additional Chinese learning resources. The content is manually written (not AI-generated) and formatted for Obsidian, allowing users to import them after cloning the repository. The project is ongoing, with more topics planned for future updates.
