Attached to the email is a file 12 October 2015 Invoice Summary.doc which comes in at least four different versions (VirusTotal results:    ) which contain a macro that looks like this example. Download locations spotted so far are:
All those download locations are on UK sites, but there are three apparently unrelated IP addresses in use:
This is saved as %TEMP%\gicage.exe and has a VirusTotal detection rate of just 1/56. That VirusTotal report and this Malwr report indicate traffic to:
18.104.22.168 (TransIP BV, Netherlands)
22.214.171.124 (Data Net SRL, Romania)
I would recommend blocking traffic to both those IPs. The payload is the Dridex banking trojan.
