A malware attack occurs when harmful software, known as malware, infiltrates a computer system or network. This software can take various forms, including viruses, worms, and ransomware, and is designed to disrupt, damage, or gain unauthorized access to data. Malware can spread through infected email attachments, malicious websites, or compromised software downloads. Once inside a system, malware can steal sensitive information, corrupt files, or even take control of the device. Organizations and individuals must implement security measures, such as antivirus programs and regular software updates, to protect against these attacks and minimize potential damage.
