What are some common techniques used to distribute malware?

### REPLY:
One effective technique to distribute malware is through targeted spear-phishing campaigns. By crafting a convincing email that appears to be from a trusted source, attackers can trick individuals into clicking on malicious links or opening infected attachments. Another method involves compromising legitimate websites and injecting malicious code into them, so that unsuspecting visitors can become infected with malware simply by browsing the compromised site.
