Malware spam: "Water Services Invoice" / "UUSCOTLAND@uuplc.co.uk" (again)

This fake invoice does not comes from United Utilities Scotland, but is instead a simple forgery with a malicious attachment. It is very similar to this spam sent a few days ago.

From     "UUSCOTLAND" [UUSCOTLAND@uuplc.co.uk]
Date     Thu, 22 Oct 2015 19:30:13 +0700
Subject     Water Services Invoice

So far I have seen three different versions of the attachment, all named 22 October 2015 Invoice Summary.doc with detection rates of about between 4/55 and 7/55 at VirusTotal [1] [2] [3] containing one of these malicious macros [1] [2] [3].

Analysis of the documents is pending, but one key indicator is that the file appears to be saved as %TEMP%\bluezone3.exe. Check back later for updates.

This VirusTotal report also identifies the following download locations:


This file has a VirusTotal detection rate of 2/54 and that report indicates network traffic to: (Linode, US)

Further analysis is pending, in the meantime I suggest that you block traffic to the above IP.

I love it when they start "I hope you are well". Have none of these people ever seen a real business communication?
