There are several common techniques for spreading malware through email attachments. One method is to disguise the malicious file as a harmless document, such as a PDF or Word file, and include it as an attachment in the email. Another technique is to use social engineering tactics to trick the recipient into opening the attachment, for example by posing as a trusted entity or by creating a sense of urgency. Additionally, attackers can exploit vulnerabilities in email clients or use macros in documents to execute malicious code when the attachment is opened.
