ABSTRACT
As Singapore accelerates its digital transformation and adoption of 5G-enabled systems, the convergence between telecommunications networks and Operational Technology (OT) environments is creating unprecedented opportunities — and equally unprecedented risks. Drawing from hands-on experience building a 5G testbed in collaboration with Nokia, SUTD and DIS, this session by Matthias Yeo provides a practitioner’s perspective on emerging 5G and OT threat landscapes.The talk will cover:
1. The 5G–OT Convergence Risk Surface
- What have been discussed in CIDEX and how it impacts Singapore
- Some of the risk Singapore is facing as well as other countries
- What are some of the attack we have simulated
- Advanced Threats in 5G Environments
- Control plane vs user plane exploitation
- GTP-U abuse, signaling manipulation, and lateral movement
- Supply chain and vendor trust risks
3. Incident Response in 5G & OT
- What must be captured during an incident (telemetry, identifiers, session context)
- Key forensic artifacts unique to 5G core networks
- Coordinating response across telco, OT engineers, and cybersecurity teams
This session is designed for cybersecurity professionals, OT engineers, telco architects, and policy stakeholders seeking practical, technical insights into defending next-generation infrastructure. Participants will leave with a clearer framework for understanding how 5G reshapes threat hunting, detection engineering, and incident response in converged environments.
