How do malware authors distribute their malicious software to unsuspecting victims?

### REPLY:
Malware authors often use botnets, which are networks of compromised computers, to distribute their malicious software. By leveraging the computing power of these infected machines, malware authors can send out massive amounts of spam emails containing malware attachments or links to malicious websites. This allows them to reach a large number of potential victims and increases the chances of successful infections.
