Silent Protocols Piercing the Air-Gap: Blind Spots in ICS Security
Speakers:
🎤 Hea-Eun Moon – Director, NSHC Inc
🎤 Sunho (Marvin) Lee – Team Lead, NSHC Inc
Industrial Control Systems (ICS) and SCADA environments power critical infrastructure and manufacturing worldwide — but how secure are the protocols running behind the scenes?
In this highly insightful talk, the speakers explore how vulnerabilities in industrial protocols such as OPC-UA, Modbus, and DNP3, along with manufacturer-specific implementations, can be leveraged to target ICS devices and engineering workstations (EWS).
Topics Covered:
🔹 ICS/SCADA attack methodologies
🔹 PLC and EWS targeting techniques
🔹 Protocol analysis and fuzzing research
🔹 Air-gap bypass attack scenarios
🔹 Security blind spots in critical infrastructure
This session provides valuable insight into the evolving threat landscape targeting industrial environments and highlights the importance of strengthening cyber resilience for critical infrastructure.
