Malware spam: "Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD" / "orders@kidd-uk.com"

This fake financial spam is not from James F Kidd, but is instead a simple forgery with a malicious attachment:

Subject:    Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD

 Please see enclosed Sales Invoice for your attention.

I have seen a single copy of this spam with an attachment invoice574206_1.doc which has a VirusTotal detection rate of 3/55.

This Malwr report indicates that in this case there may be an error in the malicious macro [pastebin]. The Hybrid Analysis report is inconclusive. This document is presumably attempting to drop the Dridex banking trojan.

UPDATE

I have received two more samples, one names invoice574206/1.pdf and the other invoice574206/1.doc. Both are Word documents (so the one with the PDF extension will not open). The VirusTotal detection rates are 7/54 and 4/55. One of these two also produces an error when run.

The working attachment (according to this Malwr report and Hybrid Analysis report) downloads a malicious binary from:

bjdennehy.ie/~upload/89u87/454sd.exe

This has a VirusTotal detection rate of 3/54. Automated analysis tools [1] [2] [3] [4] show malicious traffic to:
