What are some common techniques used to distribute malware?

### REPLY:
One effective technique to distribute malware is through drive-by downloads. This involves injecting malicious code into legitimate websites, so that when users visit these sites, the code is automatically executed on their computers without their knowledge or consent. Another method is to exploit vulnerabilities in popular software programs, such as web browsers or document readers, to deliver malware to unsuspecting users. Additionally, hackers may use botnets to distribute malware, by infecting a large number of computers and using them to send out spam emails with malicious attachments.
