548 Internet-Exposed Building Automation Devices Still Run Software Past Its Security Lifespan
A security study found 548 internet-exposed building automation devices near U.S. data centers running end-of-life products with no future security patches.
When a Factory Incident Becomes a Supply-Chain Problem
A reported share of UK manufacturers is pushing cyber risk out of the IT corner and into the boardroom, where continuity, suppliers, and recovery now matter as much as passwords.
When a Power Chain Turns Fragile: The OT Intrusion That Traveled Through Trusted Links
A late-December cyberattack on a cogeneration plant shows how remote-access paths, private cellular design, and OT trust boundaries can collide in critical infrastructure.
A High-Severity Schneider Electric Alert Lands Before the Full Map Exists
A new vulnerability notice tied to Schneider Electric products creates a familiar industrial-security problem: operators must assess risk before the exact products, versions, and exploit path are publicly clear.
The Private APN That Became a Door Into Industrial Control
A reserved mobile-network path, usually treated as controlled access, has emerged as the unusual bridge into an OT environment tied to a Polish cogeneration plant.
When a Cooling Controller Becomes a Root-Level Risk
A cluster of serious flaws in a web-managed refrigeration platform shows how maintenance features, weak access control, and command handling bugs can turn cold-chain infrastructure into an operational security problem.
Private APNs, Public Risk: The Hidden Route Into Industrial Control
A reported pivot from a wind farm into a Polish CHP plant shows how a cellular trust path can become an industrial attack surface.
Small Water Systems, Big Consequences: The Cybersecurity Gap Hiding in Plain Sight
Rising threats are colliding with thin staffing, tight budgets, and old equipment in a sector where a cyber mistake can become an operations problem.
Private Mobile Path, Public Consequences: A Polish Industrial Network Incident Raises Hard Questions
A reported incident at a Polish combined heat and power plant highlights the risks that arise when mobile connectivity and industrial control networks are not tightly separated.
Poland’s Public Web Is Under Pressure, and the Numbers Hint at a Bigger Cyber Map
A mass of affected public bodies and websites points less to a single breach than to a national exposure problem that is hard to inventory, classify, and defend.
When Isolation Becomes a Lifeline: The New Logic of OT Defense
BlackBerry's analysis puts a hard truth at the center of critical infrastructure security: disconnecting industrial systems is not enough unless operators can still communicate, coordinate, and recover.
Internet-Exposed Tank Gauges Shrink in the U.S., but the Risk Story Is Not Over
A 56% drop in observed public exposure is a meaningful shift for automatic tank gauge systems, yet it does not by itself prove the devices are now safe or fully hardened.
North Carolina Ports Under Cyber Pressure as Shared Systems Slow Three Terminals
A confirmed cyberattack disrupted IT systems at North Carolina Ports, and the operational ripple reached Wilmington, Morehead City, and Charlotte Inland Port.
Publicly Reachable PLCs Turn Water Controls Into a Cyber Fault Line
Reported targeting of internet-exposed Rockwell controllers in U.S. water and wastewater environments shows how a single exposed OT path can create operational risk far beyond the IT network.
Water Utilities on Alert as Suspected OT Intrusions Draw Federal Scrutiny
A continuing investigation into suspected activity inside water and wastewater environments underscores how fragile operational technology can be when remote access, segmentation, and asset visibility are weak.
Inside the Smart Factory’s Weakest Link: When Connectivity Becomes a Production Risk
In connected manufacturing, OT security is no longer a niche control problem - it is a question of whether a line keeps running, recovers quickly, and stays within safe operating limits.
When ERP Goes Dark: Why Manufacturing Resilience Now Depends on Enterprise IT
Manufacturing security is no longer just a shop-floor problem, because the systems that schedule materials, orders, and recovery decisions now sit deep inside the business core.
New York’s Water Cyber Fund Signals a Quiet Shift From Panic to Hardening
A $9 million grant push for 153 water systems suggests the state is treating utility cybersecurity as infrastructure maintenance, not an optional add-on.
Water Systems Become a Policy Battlefield as CISA Faces Pressure Over OT Security
A push for stronger federal action reflects a harsh reality in critical infrastructure: when operational technology is targeted, the blast radius can reach pumps, alarms, and public confidence.
Frenos Secures $1.52M to Push OT Security Toward Simulated Attack Validation
The funding announcement points to a narrower but important shift in industrial defense: using simulation, not live production testing, to study how an attacker might move through operational technology.
