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.
Even after their zero-day vulnerability turned into an n-day, attackers known as Marbled Dust or Sea Turtle continued to spy on military targets that had failed to patch Output Messenger.
With critical infrastructure facing constant cyber threats from the Typhoons and other corners, federal agencies and others are warning security for the OT network, a core technology in many critical sectors, is not powered up enough.
While hacktivists claimed more than 100 successful attacks against Indian government, education, and military targets, the attacks were overblown in most cases and often did not even happen.
Tidrone concentrated on military entities and the satellite sector, using their associated service providers and ERP software to infect not just drones but all the entities that are part of their supply chains.
