What are the common techniques used to distribute malware?

### REPLY:
One of the most effective ways to distribute malware is through targeted spear phishing attacks. By sending carefully crafted emails that appear to be from a trusted source, attackers can trick users into opening attachments or clicking on links that contain malware. Another method is to compromise legitimate websites and inject malicious code into them, which can then infect visitors with malware. Additionally, exploiting software vulnerabilities or using exploit kits can be used to deliver malware to unsuspecting users.
