Some common techniques used in malware propagation include creating phishing emails that appear to be from legitimate sources, using drive-by downloads to infect unsuspecting users, or exploiting software vulnerabilities to gain unauthorized access to systems. Additionally, hackers may use botnets to distribute malware or employ social engineering tactics to trick users into downloading and executing malicious files.
