Thirty Water Systems, One Alarm: Minnesota’s OT Incident Shows How Wide a Small Cyber Event Can Spread
A coordinated cyber campaign against Minnesota community water systems pushed state responders into action and exposed how fragile critical infrastructure can become when operational technology is dragged into the crosshairs.
When Roads Start Thinking: The Quiet Cyber Risk Hidden in Smart Infrastructure
Smart roads are moving transport from passive asphalt to a cyber-physical system, where sensors, interoperable data, and digital models can reshape maintenance, risk, and accountability.
Angola's Carrier Went Quiet, and the Timing Made It Worse
A cyberattack on Unitel disrupted voice, mobile data, and internet access nationwide, turning a telecom incident into a national resilience test hours before the company's market debut.
US and Australia Push Critical Infrastructure Toward OT Isolation
New guidance treats disconnected operation as a core resilience skill, not a last-minute improvisation, for systems that keep physical services running.
The Grid’s Quiet Specialists: Why an Interview With Emma Stewart Matters
Industrial Cyber’s Hall of Fame series turns the spotlight on a power-grid cybersecurity expert, underscoring how critical infrastructure defense depends on technical judgment long before an incident ever makes headlines.
Water Plant Controls Under Pressure: Minnesota’s OT Intrusions Expose a Fragile Surface
Several municipal water and wastewater utilities in Minnesota were targeted in coordinated operational technology attacks that disrupted automated controls, highlighting how exposed control systems can become a public-infrastructure risk.
When the Bus Can Be Touched, the Firmware Can Be Traded
A legacy KNX update flaw shows how industrial security can fail at the point where physical access meets outdated trust assumptions.
When Critical Systems Must Survive the Cut: The New Discipline of OT Isolation
Fresh joint guidance for critical infrastructure turns a hard reality into a planning problem: isolate the systems that keep essential services alive, and make sure they can run that way for longer than a few hours.
Shipyard AI Can Save Time, But It Also Rewrites the Rules of Safety
Artificial intelligence in shipyards may help prevent injuries, yet the deeper challenge is making sure safety tools do not become opaque systems that watch workers without proper control.
When Hospitals Buy Risk by Accident
ENISA’s healthcare procurement guidance turns a quiet paperwork step into a security decision that can shape the resilience of clinics, hospitals, and their suppliers.
Italy’s Health Cyber Puzzle: When Risk Is Fragmented, Defense Is Too
A national healthcare network can only defend what it can see, and Italy’s mix of regional systems, shared record services, and connected devices is making that view harder to keep consistent.
The Air-Gap Myth: Why Isolation Is Not the Same as Security
Offline networks reduce remote exposure, but removable media, insider access, supply-chain flaws, firmware trust, and side channels still define the real attack surface.
Why Exposed PLCs Turn Industrial Networks Into Open Doors
A joint U.S. warning puts internet-facing controllers at the center of a critical infrastructure risk: when PLCs are reachable from the outside, normal industrial protocols can become a path into the control layer.
When a Simulation File Becomes a Loader: Rockwell’s Arena Fix Exposes a Quiet Industrial Risk
Rockwell has patched code-execution flaws in Arena Simulation, and the case shows how trusted engineering files can turn workstation software into an entry point.
When the Screen Lies: Industrial Controllers Turned Into a Cover Story
A revised federal warning points to a dangerous OT pattern: internet-exposed PLCs and tampered HMI displays can leave operators watching a system that no longer reflects reality.
When an Old Waiver Meets a New Cyber Rule, the Waiver Loses
The Coast Guard has drawn a clear boundary in maritime compliance: a past MTSA waiver does not automatically erase cybersecurity obligations.
Stormbreaker Puts the Grid’s AI Hype Under a Harder Test
CESER’s new evaluation effort is a reminder that in power systems and OT, AI is not judged by accuracy alone but by whether it behaves safely under operational stress.
When PLCs Become Pressure Points: The Critical-Infrastructure Warning Hitting Water and Energy
U.S. agencies are flagging a familiar but dangerous pattern: vulnerable industrial controllers can turn a narrow intrusion into disruption across water and energy environments.
Industrial Cybersecurity Moves Up a Layer as A2LA Broadens ISASecure Scope
The accreditation change does not describe a breach or a flaw, but it does matter: it shapes who can validate ISA/IEC 62443 certification in industrial automation security.
When a PLC Goes Public, the Plant Becomes the Target
U.S. critical infrastructure operators are being pushed to pull Rockwell and other controllers off the public internet, because exposed OT gear changes a maintenance shortcut into a security hazard.
