A cyberattack is when digital means are used to infiltrate or damage a compter system. This may involve some form of computer virus, worm or other self-proposgating code. It may also involve more human attacks, such as phishing. Cyberattacks need not compromise a compter sysyem to casuse damage, in particular denial of service (DoS) atacks simply flood a machine with a vast level of network traffic. the The outcome of a cyber attack might be to bring donw the system, to extact information, or to leave an infiltaretd system avaiulable to itself perform attacks. For example, IOT devices typically have poor security and may be targetted, not to daage them per se, but so that they can be part of a bot army for DoS attacks on the real targets.
