OT Security Is Moving from Visibility to Verification
A new Claroty and Frenos partnership points to a growing industrial focus on testing whether controls actually hold against realistic attack paths, without putting live production at risk.
Manufacturing Draws the Sharpest Edge of Ransomware Pressure
Sector-level threat intelligence points to manufacturing as a persistent extortion magnet, where business downtime can carry more leverage than data theft alone.
The Mediterranean’s New Fault Line: When Energy and Data Share the Same Seabed
Italy’s strategic infrastructure push is being read as a cyber-physical corridor, where telecom, power, and sensing layers are increasingly described as interdependent rather than separate.
Stolen Credentials Put Australia’s Critical-Infrastructure Defenses on the Clock
A reported intrusion into a network used by a critical-infrastructure operator shows how ordinary login details can become strategic access in the wrong hands.
Why Airport Cybersecurity Breaks at the Boundaries
Airports are not just buildings with networks attached - they are tightly coupled digital ecosystems, and that makes segmentation, trust boundaries, and containment more important than any single firewall.
When the Factory Learns to Think, the Network Becomes the Weakest Joint
Physical AI is being framed as the next step for manufacturing SMEs in Piemonte and Valle d’Aosta, but the real test is whether data, robots, and OT-connected systems can be modernized without expanding cyber risk.
When a Supplier Becomes the Weakest Link in Critical Infrastructure
For operators of essential services, vendor choice is no longer just procurement - it is a long-term cyber-resilience decision shaped by regulation, continuity, and exit risk.
Link11 Bets on a Rebuilt DDoS Shield as Network Floods Keep Evolving
A July 1 announcement in Frankfurt points to a simple truth: defending against modern DDoS traffic is now a routing and filtering problem as much as a capacity problem.
Washington Pulls the Levers on the Internet’s Hidden Backbone
The FCC’s push to tighten oversight of submarine cable systems turns a little-seen part of telecom infrastructure into a high-stakes security gate.
Water Plants Under Pressure: Why Exposed Control Gear Still Draws Strategic Attention
Water and wastewater networks remain attractive targets when HMIs, PLCs, and weak segmentation leave operational technology easier to reach than it should be.
The Quiet Weak Link in Water Security Is Now Getting a Federal Fix
NIST has issued guidance for water utilities that rely on remote access, spotlighting a control path that is convenient for operators but risky for critical infrastructure.
When a Water Threat Stays Virtual: The OT Test Behind Cal Water’s Incident
A California utility faced a public disruption claim, but the key finding was narrower and more revealing: no evidence of OT activity, which keeps the case in the realm of verified cyber risk rather than confirmed physical-process interference.
When Recovery Becomes a Shortcut: The UEFI Password Problem Hidden in WinRE
A reported bypass in the Windows recovery path shows how a pre-boot security control can weaken when firmware and recovery logic share the same trust assumptions.
The Hidden Engineering Behind a “Simple” iButton Reader
A more convenient reader sounds minor, but on a 1-Wire touch device the difference between smooth use and failed reads lives in the details.
When a Rail Radio Layer Blinks, a Nation Feels It
Germany’s brief rail disruption is a reminder that a legacy communications system can carry outsized operational risk even when the tracks themselves are fine.
When a Single Seabed Cut Becomes a National Connectivity Test
A damaged Egypt-Syria submarine cable forced traffic onto alternate routes through Cyprus and Turkey, showing how critical internet resilience depends on physical redundancy as much as software security.
When the Numbers Lie: The Quiet OT and IoT Attack That Changes Reality
A manipulation attack does not have to stop a plant to do damage - it can quietly distort the data operators trust, turning process visibility into a false sense of safety.
Italy’s Critical Infrastructure Test: When CER and NIS2 Have to Work as One
The real challenge is no longer writing resilience rules, but making sure critical services, regulators, and suppliers can use them without gaps, silos, or blind spots.
How Gcore Helped Ucom Harden Live Broadcast Paths During Armenia's Election Window
A reported Network Layer DDoS protection deployment shows how telecom operators try to keep public-facing media services reachable when election-period traffic becomes a security problem, not just a bandwidth one.
NIST Turns OT Backups Into a Recovery Discipline, Not a Checkbox
A new quick-start guide treats industrial backups as part of resilience engineering, signaling that restore readiness matters as much as storage.
