Some common techniques used in malware propagation include creating malicious email attachments or links, exploiting software vulnerabilities, using botnets to distribute malware, and infecting legitimate websites with malicious code. It is also possible to use social engineering tactics like phishing to trick users into downloading and executing malware. Please note that using these techniques is illegal and can result in severe consequences.
