About daniel dayan
Hey! I’m Daniel Dayan, a cybersecurity researcher and CTF competitor.
I build free, offline-first tools for the community like ZeroBox (a tactical CTF tracker, 0day reverse shell builder, and 400+ offensive field notes) to help students and penetration testers crush labs like Hack The Box and TryHackMe without paying for expensive software.
If my tools, cheatsheets, or writeups helped you pop a shell, pass an exam, or saved you time during a CTF, buying me a coffee fuels late-night coding and keeps everything 100% free and open-source! ⚡
