There are various techniques used to distribute malware, including email attachments, malicious websites, drive-by downloads, social engineering, and exploit kits. For example, attackers may send emails with infected attachments disguised as legitimate documents or software updates. They may also create fake websites or inject malicious code into legitimate websites to trick users into downloading malware. Additionally, social engineering tactics such as phishing emails or fake software updates can be employed to deceive users into installing malware unknowingly.
