Powering Resilience: Unmasking Hidden Threats to Energy Grids

Energy systems are the backbone of oursociety, and protecting them is more critical than ever. A recent report by Dragos (“2025 OT/ICSCYBERSECURITY REPORT”) sheds light on the growing risks tooperational technology (OT) and industrial control systems (ICS), especially inenergy grids.

What's Going On?
The report shows that many energy systems use outdated technology thatattackers can easily exploit. For example, basic methods like using oldprotocols such as SMBv1 allow attackers to gain access and move acrossnetworks. Vulnerabilities from 6 to 10 years ago are still being used, puttingcritical systems at risk. One striking case involved a malware calledFrostyGoop, which changed readings on industrial controllers and caused heatingoutages in Ukrainian apartments during winter.

Why Energy Grids Are at Risk
Energy grids often mix modern digital controls with old systems that weren'tbuilt to face today's cyber threats. A breach in these systems can lead towidespread blackouts, disrupt services, and even cause physical damage. Thereport highlights that many of these attacks could set off chain reactionsacross interconnected networks, making the risk even higher for the energysector.

What Can Be Done?
The report urges energy grid operators to adopt a strong, layered approach tosecurity:

• Network Segmentation:     Divide networks so that if one area is breached, the attack doesn’t spread     to the entire system.
• Secure Remote Access: Use     strong controls like VPNs, jump hosts, and separate domain controllers to     block unauthorized access.
• Modernize Legacy Systems: Focus     on updating and patching older systems to close known gaps.
• Continuous Monitoring: Keep     an eye on network traffic with advanced tools to catch unusual activity     early.

Working Together for a Safer Future
The findings remind us that cyber threats are growing, and energy grids are aprime target. It’s essential for industry players to work together—sharinginformation, following best practices, and updating their security measuresregularly. By taking these steps, energy grid operators can build strongerdefenses and keep our power supply safe.

Protecting our energy infrastructure is notjust about technology; it’s about keeping our daily lives and national securityintact. The journey to a secure future starts with recognizing the risks andtaking action today.
