Espilon CTF is a hardware, IoT & OT-focused Capture The Flag competition. No web exploitation, no classical pwn — this is about real-world embedded security: soldering irons, logic analyzers, protocol decoders, and raw RF signals.

Set in the universe of Serial Experiments Lain, you'll infiltrate the Clinique Sainte-Mika medical network, probe Tachibana General Laboratories SCADA systems, and navigate the dark corridors of Cyberia — all through authentic industrial and embedded protocols.
