Malware is malicious software designed to harm, exploit, or otherwise compromise computer systems and networks.
Description
Malware, short for malicious software, encompasses a variety of software programs that are intentionally designed to harm or exploit computers, networks, and users. Common types of malware include viruses, worms, trojans, ransomware, and spyware. Malware can infiltrate systems through various methods, such as infected email attachments, malicious downloads, or compromised websites. Once inside a system, malware can steal sensitive information, corrupt files, disrupt services, or even take control of a user's device. For instance, ransomware, like the infamous WannaCry attack in 2017, encrypts a user's files and demands a ransom for their release. Moreover, spyware can monitor user activities and gather personal data without consent, posing significant privacy risks. The impact of malware can be devastating for individuals and organizations alike, leading to financial losses, data breaches, and reputational damage. Therefore, robust cybersecurity measures, including updated antivirus software and user education, are crucial to defend against these threats.
Examples

- Spyware: Pegasus, which has been used to monitor mobile devices stealthily.
Additional Information
- Malware can spread rapidly through networks, making timely detection and response essential.
- Regular software updates and strong passwords can help reduce the risk of malware infections.
