What are some common techniques used to distribute malware?

### REPLY:
One effective technique to distribute malware is through drive-by downloads. By exploiting vulnerabilities in a user's web browser, the malware can be automatically downloaded and installed without the user's knowledge. Another method is to disguise the malware as a legitimate software update or application, tricking users into willingly installing it. Additionally, hackers can use botnets to distribute malware, using a network of infected computers to send out spam emails with malicious attachments.
