The new Zscaler ThreatLabz 2025 report reveals a massive surge in cyberattacks targeting critical infrastructure. Attacks on the energy sector’s IoT and Operational Technology (OT) systems increased by 387% over the previous year, with manufacturing and healthcare also seeing significant spikes.
Business Impact
This trend confirms that attackers (including nation-states like Volt Typhoon) have shifted their focus to OT and IoT as the new, high-value frontier. A successful attack can disrupt physical operations, causing power outages, halting production lines, and posing a direct threat to public safety.
Why It Happened
The convergence of IT and OT networks, combined with the proliferation of unpatched or misconfigured IoT/OT devices, has created a massive, vulnerable attack surface that attackers are now systematically exploiting.
Recommended Executive Action
Mandate a full asset inventory of all IoT and OT devices on your network. Enforce strict network segmentation to isolate critical OT systems from the IT network. Prioritize a zero-trust approach for any device connecting to critical operational environments.
