AI-Style Scripts Put Siemens S7 Controllers in the Crosshairs
U.S. agencies warned about a campaign targeting Siemens S7 PLCs with scripts described as AI-generated and disguised as ordinary industrial monitoring tools.
Capitol Hill Eyes the Grid’s Weak Link: Cryptography Before Quantum Hardware Arrives
A bipartisan Senate bill puts post-quantum readiness into critical-infrastructure policy, even though the technical threat remains forward-looking.
When the Cooling Room Becomes the Front Door
A reported count of 6,300 internet-reachable ICS and BAS devices points to a quiet but consequential exposure inside US data centers: the control layer behind uptime.
AI in OT Has Left the Slide Deck - and That Changes the Risk
A discussion framed around the move from hype to operational reality in industrial AI points to a harder truth: once AI touches OT, safety, availability, and change control matter as much as model performance.
When Water Becomes a Target: The Hidden Cyber Risk Behind a Geopolitical Resource
A commentary about water politics also points to a harder truth: once a resource is digitized, the control systems around it can become part of the threat model.
Europe’s Rail and Sea Routes Just Got a Cyber Stress Test
A major EU exercise put railway and maritime disruption scenarios under pressure, revealing why transport security is as much about coordination as it is about code.
When Device Security Becomes a Signal Problem: Crytica and Forescout Connect the Dots
An announced integration between Crytica Security, Forescout, and Vistaro points to a familiar enterprise dilemma: turning device-level alerts into something operators can actually trust and act on.
When OT Data Enters the SOC, the Blind Spot Gets Smaller
Nozomi Networks and Sophos are tying industrial visibility into investigation workflows, a move that could narrow one of security’s most stubborn gaps: seeing what happens when IT and OT overlap.
When Visibility Becomes a Trap: Why OT Networks Need Real Protection
In industrial environments, seeing every device is useful, but it is not a defense unless the network itself can enforce limits, isolate risk, and preserve safety.
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.
