Today I launched Hackbook to have a place to store my notes for offensive security techniques that I acquire. My goal is to eventually take the OSCP, and hope to have a nice notebook of findings to help me with the killchain.
I used OpenAI Codex to help convert this blog (specifically the sidebar) into a hierarchical view for browsing the notes. Also added a master cheatsheet component, so any code blocks nested in the pages will get pulled out into a master cheatsheet.
Hackbook also has the latest MITRE ATT&CK 19.1 matrix, which I hope to link specific techniques directly to MITRE for easy reference.
I hope to slowly work on filling that out over the coming months!
