While cybersecurity wasn’t the root cause of this incident, its awareness and measures can greatly affect outcomes when system controls are stressed or disrupted. For operators of critical assets, the relevance lies in the system-level lessons around visibility, coordination, and control integrity.
In March 2026, the U.S. Federal Communications Commission (FCC) expanded its “Covered List.” Although the regulation specifically targets consumer-grade routers, its implications extend into industrial and critical infrastructure environments.
Five cybersecurity bills aimed at strengthening protections for national energy infrastructure have advanced, reflecting bipartisan concern over growing threats to grid and operational systems and reinforcing the need for utilities to address long-standing exposure and architectural risks in operational technology (OT) systems.
In October 2025, the Canadian Centre for Cyber Security issued an Alert warning CISO and decision makers of increasing cyber-attacks exploiting internet-accessible industrial control systems (ICS). Reported incidents included tampering with water pressure values, triggering false alarms in an oil & gas facility, and manipulating temperature and humidity levels in a grain drying silo. These individual companies may not be direct targets of adversaries but have become victims of opportunity to gain media attention and undermine public trust.
In a joint advisory, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and partners detailed ongoing cyber activity targeting industrial control systems (ICS). To cause disruption and gain publicity, hacktivists often target critical infrastructure, ranging from water treatment facilities to oil well systems. They exploit exposed services, weak authentication, and poor network segmentation in legacy operational technology (OT). Although these hacktivists are generally unsophisticated and mostly cause only temporary loss of view, they show lack of consideration for human safety and incur substantial labor costs associated with operational downtime and network remediation.
BlackBear’s observations: Data Diodes are used to segment networks in a simple and effective way.
BlackBear’s observations: Firewalls are inadequate for this type of attack, since the command format itself is valid, even though the value is incorrect.
BlackBear’s observations: Two-way communication can cause possible exposure of critical assets.
