Which of the following statements is true for malwares?

The statement that all of the provided options are true for malware is accurate because malware encompasses a wide range of programs that have several common characteristics.

Malware refers to malicious software designed to harm, exploit, or otherwise compromise information systems. One key characteristic is that many types of malware, including viruses, can infect other programs; this means that they can attach themselves to and alter executable files, potentially spreading from one system to another.

Additionally, malware often propagates effectively by attaching itself to files and emails, serving as a method of distribution that can lead to widespread infections. This behavior highlights the importance of cybersecurity measures such as scanning attachments and avoiding suspicious links.

Another important aspect of malware is that while many types can cause immediate damage, not all malware is overtly destructive. Some may be designed to collect sensitive data, monitor behaviors, or create backdoors for future access without immediately damaging files or systems. This lack of visible harm can make malware particularly insidious, as users may not realize they are infected for a long time.

Given these points, all the statements are true, making the option that encompasses each of these claims correct.
