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.
UPGRADE and DigiSeals Programs at ARPA-H Remain Fully FundedA U.S. federal grant effort to develop autonomous medical device patching platforms for hospitals evaded the budget-cutting knife of the Trump administration. Program boosters hope to automate cyber defenses so that hospitals of any size can more quickly patch vulnerabilities.

The Computer Emergencies Response Team of Ukraine (CERT-UA) has disclosed details of a new campaign that has targeted governments and municipal healthcare institutions, mainly clinics and emergency hospitals, to deliver malware capable of stealing sensitive data from Chromium-based web browsers and WhatsApp
Playbook Aims to Help Healthcare, Public Sector Manage AI Vendor Security GapsThe Health Sector Coordinating Council released guidance to help the healthcare and public health sector better manage the explosion of third-party AI vendor cyber risk concerns they face, especially as the technology is embedded in all sorts of products.
'We've Yet to Find Any Mission That Can Work Without Power or Water'The Air Force is the first, and so far only, American military service to have an office dedicated to OT cybersecurity, blazing a path other services should follow, according to officials and industry observers. These are systems without which the United States can't go to war.
A digitally signed adware tool has deployed payloads running with SYSTEM privileges that disabled antivirus protections on thousands of endpoints, some in the educational, utilities, government, and healthcare sectors. [...]
Patients Allege Health Entities Did Not Get Consent to Record ConversationsProposed federal class action litigation alleges that two California healthcare organizations violated patient privacy in their use of an AI-enabled ambient tool that records, transcribes, and processes sensitive conversations between clinicians and patients without individuals' consent.
Why Cyber Risk Is Now Shaped as Much by Nations as by HackersWars are becoming more frequent, and are no longer only kinetic. They are just as active in the cyber world, with impacts much larger than can be imagined. This also leads to state-sponsored hacktivists targeting the critical infrastructure of nations.
