BLOOD is a team of cybersecurity enthusiasts specialized in CTFs, red teaming, and ethical hacking. We operate in the shadows, we learn in public.

We are a collective of cybersecurity professionals who share a deep curiosity for system internals, networks, and adversarial thinking. We compete in CTF competitions across the globe and document our tactics and strategies through detailed write-ups and open-source tooling. BLOOD is about pushing the envelope and never backing down from a challenge.
