What are some common techniques used to distribute malware?

### REPLY:
One of the most effective techniques to distribute malware is through social engineering, where attackers trick users into downloading and executing malicious files. Another method is through the use of malicious advertisements or malvertising, where legitimate websites unknowingly display ads that contain malware. Attackers can also exploit vulnerabilities in software applications or operating systems to deliver malware payloads, which can be done through drive-by downloads or by using exploit kits.
