### REPLY:
One common technique to deliver malware through email attachments is to disguise the attachment as a harmless document, such as a PDF or Word file. The attachment may contain a hidden script or macro that, when executed, downloads and installs the malware onto the victim's computer. Another technique is to create a compressed file, such as a ZIP or RAR file, that contains the malware. This can help bypass email filters and increase the chances of successful infection.
