Malware spam: "Proof of Delivery Report: 16/03/16-17/03/16" / UKMail Customer Services [list_reportservices@ukmail.com]

This spam does not come from UKMail but is instead a simple forgery with a malicious attachment:

At the time of writing I have seen just a single sample with an attachment named poddel-pdf-2016031802464600.docm which has a VirusTotal detection rate of 9/55. This Malwr report for the sample shows a file download from:

kervanburak.com/wp-content/plugins/hello123/r34t4g33.exe

There will be many other versions of the attachment with different download locations. This binary has a detection rate of 8/55 and this Malwr report and Hybrid Analysis  show network traffic to:

64.147.192.68 (Dataconstructs, US)

I recommend you block traffic to that IP. The payload appears to be the Dridex banking trojan.

UPDATE 1

This DeepViz report shows some additional IP addresses contacted:

64.76.19.251 (Level 3, US / Impsat, Argentina)
91.236.4.234 (FHU Climax Rafal Kraj, Poland)
188.40.224.78 (Hetzner / NoTaG Community, Germany)


UPDATE 2
