    • A cyberattack (or cyber attack) occurs when there is an unauthorized action against computer infrastructure that compromises the confidentiality, integrity, or availability of its content.

      The rising dependence on increasingly complex and interconnected computer systems in most domains of life is the main factor that causes vulnerability to cyberattacks, since virtually all computer systems have bugs that can be exploited by attackers. Although it is impossible or impractical to create a perfectly secure system, there are many defense mechanisms that can make a system more difficult to attack.

      Perpetrators of a cyberattack can be criminals, hacktivists, or states. They attempt to find weaknesses in a system, exploit them and create malware to carry out their goals, and deliver it to the targeted system. Once installed, the malware can have a variety of effects depending on its purpose. Detection of cyberattacks is often absent or delayed, especially when the malware attempts to spy on the system while remaining undiscovered. If it is discovered, the targeted organization may attempt to collect evidence about the attack, remove malware from its systems, and close the vulnerability that enabled the attack.

      Cyberattacks can cause a variety of harms to targeted individuals, organizations, and governments, including significant financial losses and identity theft. They are usually illegal both as a method of crime and warfare, although correctly attributing the attack is difficult and perpetrators are rarely prosecuted.

    • A cyberattack is any type of offensive manoeuvre employed by nation-states, individuals, groups, or organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system. [1] These can be labelled as either a cyber campaign, cyberwarfare or cyberterrorism in different context. Cyberattacks can range from installing spyware on a personal computer to attempts to destroy the infrastructure of entire nations. Cyberattacks have become increasingly sophisticated and dangerous as the Stuxnet worm recently demonstrated. [2] User behavior analytics and SIEM are used to prevent these attacks. Legal experts are seeking to limit use of the term to incidents causing physical damage, distinguishing it from the more routine data breaches and broader hacking activities.
