LatAm Tightens OT Defenses Amid Industrial Risk

A technical analysis from Shieldworkz, an IDB guide and a Cryptonomist article all point to rising OT/ICS exposure in water, energy and manufacturing across Latin America and beyond. The pressure is increasing on PLCs, HMIs, SCADA and industrial networks connected to the internet, along with stronger demands for governance, detection and insurance coverage.

What does Shieldworkz's technical analysis show about OT exposure?

A Shieldworkz technical analysis of Iranian campaigns against OT/ICS describes a pattern of exploitation targeting PLCs, HMIs, SCADA systems and remote field communications exposed to the internet. The activity spans water and wastewater, energy, government facilities, health care and manufacturing.

The report recommends removing all direct exposure of PLCs, RTUs and HMIs to the public network. It also suggests auditing IP ranges with tools such as Shodan and Censys to verify that no OT ports remain open, including 44818, 502, 102, 2222, 20256 and 22.

What does the Americas OT/ICS & SCADA Cybersecurity report add?

Shieldworkz expands that assessment in its Americas OT/ICS & SCADA Cybersecurity report, which adds context on the rise in incidents across manufacturing, energy, oil and gas, transportation and water utilities.

The report documents pre-positioning operations in OT environments across energy, water and telecom sectors in North America, attributed to groups such as Volt Typhoon, Sandworm and actors linked to the IRGC. It also says the Ransomware as a Service model is already deploying operators with knowledge of PLC logic and SCADA architecture.

It further warns that legacy ICS exposure through unauthenticated Modbus, DNP3 and BACnet ports is critical, and identifies the United States as the country with the largest number of ICS ports accessible from the internet.

Why is the gap between IT and OT shrinking?

A separate analysis published by Cryptonomist, citing Dragos recommendations on AI-assisted attacks, says those attacks are compressing the time between compromise of IT networks and attempts to breach OT.

The result, according to that material, is that defenses based only on prevention are no longer enough. For critical infrastructure, the recommendation is to complement firewalls, segmentation and patching with OT-specific network visibility and detection capabilities for internal control traffic, in line with SANS' Five Critical Controls for ICS.

What governance framework does the IDB propose for Latin America?

In Latin America, the IDB guide for boards on cyber risk management in OT environments provides a regional governance framework.

The document says the digitization of energy, water, transportation and manufacturing has raised OT risk exposure, and that boards must add specific cyber-physical risk metrics, operational disruption scenarios and clear responsibilities for ICS security. The guide aligns with the emergence of regulatory frameworks such as those that define operators of vital infrastructure in countries across the region.

What warning does NextGuard Insurance add about data centers?

In parallel, a technical note from NextGuard Insurance on cyber insurance for data centers in Latin America stresses that these operators concentrate critical OT infrastructure, from cooling and power to humidity control and fire suppression. A compromise, the note says, can escalate into large-scale cyberphysical impacts affecting hundreds of companies at once.

NextGuard recommends that policies include explicit coverage for attacks on OT/ICS systems, a sign that the regional insurance market is already factoring in the growing industrial and critical infrastructure risk tied to OT.
