Definition: The term "cyber attack" refers to an unauthorized or malicious attempt by a computer system or network to exploit vulnerabilities, gain access to sensitive information, or disrupt operations, data, or networks. It's a form of cybercrime that involves hacking into a target's systems with the intent to steal personal or financial information, sabotage services, or cause damage to networks. The precise definition can vary depending on the context and type of attack. Generally, it involves exploiting vulnerabilities in software, hardware, network protocols, and security systems, often through malicious code or unauthorized access attempts. The purpose may be for criminal gain, business disruption, or other unethical purposes. In many cases, cyber attacks are not only illegal but also have severe societal impacts such as loss of data, financial losses, damage to reputation, and even potential legal consequences. For these reasons, it's crucial to stay vigilant against cyber threats and to implement robust security measures to protect sensitive information and networks from unauthorized access or unauthorized use. In general, the goal is often to disrupt operations, steal personal information, sabotage services, or cause significant harm to an organization or its customers.
