Analysis Summary
Emotet is a Trojan that is primarily spread through spam emails (malspam). The infection may arrive either via malicious script, macro-enabled document files, or malicious link. Emotet emails may contain familiar branding designed to look like a legitimate email. Emotet may try to persuade users to click the malicious files by using tempting language about “Your Invoice,” “Payment Details,” or possibly an upcoming shipment from well-known parcel companies. Emotet has gone through a few iterations. Early versions arrived as a malicious JavaScript file. Later versions evolved to use macro-enabled documents to retrieve the virus payload from command and control (C&C) servers run by the attackers.
