It has mostly been used to attack the banking industry. Emotet can launch several malware payloads depending on the target system after deployment. Emotet is frequently used as a downloader for other malware and is a particularly common delivery method for banking Trojans such as Qakbot and TrickBot. Emotet can steal data such as saved user passwords on the browser by eavesdropping on network traffic. Its modules focus on credential theft, email theft, and spamming.

Emotet operators usually try to get users to click the malicious files by using lures like “YourInvoice,” “Payment Details,” or possibly an upcoming shipment from well-known parcel companies.
