The Emotet Trojan gang has started to send Christmas themed emails that invite you to Christmas parties. The emails ask you to view an attached menu to select something you will bring and for you to wear your ugliest Christmas sweater to the party. When a user opens the attachment it will say that the recipient must click on ‘Enable Editing’ or ‘Enable Content’ in order to view it. A later batch of spam emails pretend to be looking for the recipient’s holiday schedule and will use mail subjects like: holiday schedules.
