Raúl Calvo Laorden · r4ulcl
Senior Offensive Security Engineer & Pentester
8+ years across web, infrastructure, Active Directory and Wi-Fi. I design realistic attack paths, automate repeatable chains, and turn complex ideas into practical skills through hands-on labs and workshops.
AboutLink to heading
My current priority is the research and development of new tools and methods, and teaching through clear, lab-driven training. I continuously improve through structured study, experimentation and knowledge sharing.
- Research & teaching: I design lab-based exercises, deliver workshops and document methodologies so others can reproduce results safely.
- Homelab: I maintain a personal micro-datacenter with multiple servers and services to prototype, test and harden techniques at scale.
- Tooling: In my spare time I develop offensive security tools and automation, mostly with Go, Docker and git.
- WiFiChallenge: Author of WiFiChallenge Lab, a 100% virtualized realistic lab to learn and practice Wi-Fi hacking, and creator of the Certified WiFiChallenge Professional (CWP) certification.
- Themes: Dracula or Solarized dark.
