Emotet Malware Now Wants You To Upgrade Microsoft Word
Emotet switched to a new template this week that pretends to be a Microsoft Office message stating that Microsoft Word needs to be updated to add a new feature.
Emotet is a malware infection that spreads through emails containing Word documents with malicious macros. When opening these documents, their contents will try to trick the user into enabling macros so that the Emotet malware will be downloaded and installed on the computer.
Once the malware is installed, Emotet will use the computer to send spam emails and ultimately install other malware that could lead to a ransomware attack on the victim’s network.

Emotet spam campaigns use a variety of lures to trick recipients into open an attachment, such as pretending to be invoices, shipping notices, resumes, or purchase orders, or even COVID-19 information, as shown below.

When opened, these attachments will prompt a user to ‘Enable Content’ so that malicious macros will run to install the Emotet malware on a victim’s computer.
