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.

Infecting cops' computers is one way to put a target on your back The Feds have sanctioned a Russian national accused of using LockBit, Babuk, and Hive ransomware to extort a law enforcement agency and nonprofit healthcare organization in New Jersey, and the Metropolitan Police Department in Washington DC, among "numerous" other victim organizations in the US and globally.…
The U.S. Justice Department has filed charges against a Russian citizen named Mikhail Pavlovich Matveev (also known as Wazawaka or Boriselcin) for involvement in three ransomware operations that targeted victims across the United States. [...]
Operational technology (OT) cybersecurity is a challenging but critical aspect of protecting organizations' essential systems and resources. Cybercriminals no longer break into systems, but instead log in – making access security more complex and also more important to manage and control than ever before. In an effort to solve the access-related challenges facing OT and critical infrastructure
