What are some common techniques used to distribute malware?

### REPLY:
One effective technique to distribute malware is through email spam campaigns. By sending out large volumes of emails containing malicious attachments or links, unsuspecting users can unknowingly download and execute the malware. Another method is to hijack legitimate websites and inject malicious code into their pages, which can then infect visitors. Additionally, exploiting software vulnerabilities or using drive-by downloads on compromised websites are also popular ways to distribute malware.
