Cyber warfare refers to the use of digital attacks by one country or entity against another, with the goal of causing disruption, damage, or gaining strategic advantage in areas like national security, economy, and infrastructure. These attacks can include hacking into government systems, critical infrastructure (such as power grids and water supplies), military networks, and private organizations. Methods often involve malware, ransomware, denial-of-service (DoS) attacks, and espionage. Cyber warfare can disrupt services, steal sensitive data, and weaken a nation’s defense capabilities without the need for traditional physical warfare. As reliance on technology grows, cyber warfare becomes an increasingly critical area of modern conflict.
