Background for this topic.
Critical infrastructure includes systems and assets vital for public health, safety, and economic stability, such as power grids, water treatment, transportation networks, and healthcare facilities. These systems often combine physical components with industrial control systems (ICS) and operational technology (OT) that manage essential services in real time.
From an information-security perspective, critical infrastructure faces risks like unauthorized access to control systems, disruption of service availability, and manipulation of sensor data. Defending these assets requires specialized security measures tailored to ICS environments, including network segmentation, strict access controls, and continuous monitoring for anomalies. Ensuring resilience also involves coordinated efforts between operators and government agencies to address vulnerabilities unique to legacy systems and proprietary protocols.
Fragmented Governance and Scarce Resources Make America's Water Sector VulnerableAmerica's water utilities are the nation's most cyber-vulnerable critical service sector, but their cybersecurity is overseen and supported by an ill-fitting patchwork of government agencies and most lack the resources to meet the threat they face.
Ransomware and vendor breaches persist. The "2026 Data Breach Investigations Report" (DBIR) highlights how evolving social engineering tactics make the sector more vulnerable.
Recent Hacks Underscore Persistent and Growing Threats to Smaller OrganizationsSmall and mid-sized healthcare organizations - including medical specialty practices and regional clinics - continue to fall victim disproportionately to hacking incidents, including ransomware attacks and data thefts - affecting large populations of patients. Why does this keep happening?
Appeals Court Weighs Pentagon Authority Over Frontier AI ProvidersA majority of judges on a U.S. federal appeals court appeared disposed to allowing Defense Secretary Pete Hegseth to bar Anthropic from future military work for posing national security risk. Oral argument held Tuesday in the U.S. Court of Appeals for the D.C. Circuit was Anthropic's latest salvo.
Incident Involved an Unnamed Third-Party VendorNew York City's municipal healthcare system is notifying nearly 2 million patients of a hacking incident discovered earlier this year involving a third-party vendor. The breach compromised a long list of information, including biometric data such as fingerprints.
Déjà Vu: Is Mythos in Hands of Bad Actors Akin to Cobalt Strike, Brute Ratel Abuse?Anthropic's Claude Mythos and similarly powerful artificial intelligence tools pose elevated cyber risk to the healthcare sector, warns a new report. Addressing the onslaught of newly discovered bugs will require healthcare organizations to evolve their vulnerability mindsets.
