What are some common techniques used to deliver malware to unsuspecting users?

### REPLY:
One common technique to deliver malware is through drive-by downloads, where a user unknowingly downloads malware when visiting a compromised website. Another method is through email attachments, where the malware is disguised as a harmless file such as a PDF or Word document. Additionally, malware can also be spread through infected USB drives or by exploiting vulnerabilities in outdated software on a user's system.
