What are some common methods used to distribute malware?

### REPLY:
One common method to distribute malware is by exploiting a zero-day vulnerability in a popular software application, such as Adobe Flash or Microsoft Office. Another effective technique is to send phishing emails with malicious attachments or links, tricking users into downloading and executing the malware. It is also possible to hide malware in seemingly harmless downloads, such as pirated software or media files. Additionally, drive-by downloads from compromised websites and infected USB drives are widely used to spread malware.
