What are some techniques used to distribute malware?

### REPLY:
There are several techniques that can be used to distribute malware. One common method is through email attachments, where the malware is disguised as a legitimate file or document. Another technique is drive-by downloads, where the malware is automatically downloaded when a user visits an infected website. Malware can also be distributed through malicious advertisements, infected USB drives, or by exploiting vulnerabilities in software or operating systems.
