The name cyber-warfare itself suggests that it essentially involve a network based conflict where two parties are involved and attacks each other with a political motivation. This is an attribute for the nation-states to involve against each other, particularly for military or other strategic purposes and cyber spying. Though it is usually used by the nation-states to attack each other, it also involves terrorist groups or hackers to fulfill the same goal for the particular nation.
Cyberwarfare often takes various forms, such as-
Form of viruses and malwares which are used for attacking and taking down necessary supplies like water, transportation, electricity or military infrastructures.
Another attack takes the form of denial-of-services (DoS) attacks that prevents the users from accessing particular computer systems or networks.
It also involves hacking into critical data centers from institutions or governmental organizations.
A form of threat involves ransomware that holds the system blocked until the ransom is paid.
Examples of cyberwarfare
Though there are several instances of a nation waging war through cyber system, but the earliest is probably the stuxnet worm which was used to attack Iran’s nuclear programs in 2010. The attack was targeted to SCADA (supervisory control and data acquisition) systems and was tactfully spread through USB devices. Comic relief lies in the fact that both United States and Israel was associated with the development of stuxnet and hence none of them acknowledged the incident.
