RedAlert ICS CTF
Coverage of the RedAlert industrial control systems CTF, simulating real-world operational technology cyber attacks.
Summary
In this guided tour from DEF CON 30, contest organizers walk through the RedAlert ICS/SCADA Capture The Flag arena, featuring an elaborate physical scale model city wired to industrial control systems. At 01:00, the organizers inspect scale simulations of critical nuclear facility components, including spent fuel pool cooling loops and uranium enrichment centrifuges.
The organizers detail the multi-vendor protocols featured in the competition at 02:00, including Siemens S7, Modbus, and DNP3 architectures. They display the hardware kits provided to competitors at 02:45—comprising HackRFs, RTL-SDRs, Raspberry Pis, and Teensy microcontroller boards to execute RF attacks against industrial cranes. At 03:45, they break down a successful exploit where a team remotely breached human-machine interfaces (HMIs) and programmable logic controllers (PLCs) to trigger a full municipal blackout.
