What is the main characteristic of malware?

The main characteristic of malware is its ability to take control or damage infected endpoints. Malware refers to malicious software designed to disrupt, damage, or gain unauthorized access to computer systems and networks. Its purpose is often destructive or intrusive, aiming to steal personal information, encrypt data for ransom, or exploit system vulnerabilities. By taking control of a device, malware can operate secretly and execute harmful activities without the user's consent or knowledge.

While some forms of malware may exhibit a tendency to spread quickly or might require user interaction, these aspects are not defining traits. The notion that malware acts as a benign application is fundamentally incorrect, as malware's very definition revolves around its malicious intent. Moreover, the requirement for user approval for installation applies more to certain legitimate software or applications rather than malware, which often seeks to evade detection and circumvent permissions to successfully infiltrate systems. Thus, the core aspect of malware lies in its capacity to compromise or damage devices, making the assertion about it taking control or damaging endpoints the most accurate representation of its nature.
