From: Colin Fox [email@example.com]The attachment is Sales Invoice 519658.pdf [VT 2/57] This spam drops the Dridex banking trojan, but unlike other recent runs the attachment is a PDF file rather than an Office document. In fact, the PDF file contains a script that generates and drops a Word document named 6.doc [Malwr report, Payload Security report] [VT 4/55] which in turn contains a malicious macro that looks like this [pastebin].
