What is an example of a cyber threat to transportation systems?

Ransomware attacks on critical infrastructure exemplify a significant cyber threat to transportation systems. These attacks involve malicious software that encrypts data and renders systems inoperable until a ransom is paid. Transportation systems, which rely heavily on computer networks for operations, communication, and management, can be severely disrupted by such attacks. A successful ransomware attack can lead to delays, safety risks, financial losses, and a breach of sensitive data related to passengers and goods.

In contrast, while data entry errors, physical theft of equipment, and natural disasters can negatively impact transportation systems, they do not directly involve cyber elements. Data entry errors typically arise from human mistakes and do not represent a cyber threat. Physical theft is related to tangible assets rather than cyber vulnerabilities. Natural disasters, although they can disrupt operations significantly, are environmental in nature and not classified as cyber threats. Thus, ransomware attacks specifically highlight the risks posed by malicious cyber activities in the context of transportation systems.
