Cyber attacks are malicious attempts to breach the security of computer systems or networks. These attacks can take various forms, including malware, phishing, and denial of service. The goal is often to steal sensitive information, disrupt services, or extort money from victims. One of the most notorious types of cyber attacks is ransomware, where attackers encrypt a victim's data and demand a ransom for its release. Organizations and individuals alike must remain vigilant and implement robust security measures to protect against these evolving threats.
