From: Milan Bell [Milan.Bell5@viuz-en-sallaz.fr]The rather rude pitch here is a canny bit of social engineering, aimed to make you open the link without clicking. I have only seen one sample of this at present and I guess that the details vary from email to email. In this case the attachment was called pastdue_tovictimdomain.tld340231.zip containing a malicious script pastdue60121342016.js.

Hope you are good.
Yesterday and the day before my colleague (Glover Hector) sent you a request regarding the invoice INV_6325-2016-victimdomain.tld past due.
I kindly ask you to give us a reply finally. We're getting no answers from you. Please stop ignoring invoice requests.
Many thanks and good luck
