Malware spam: "Documents from work." / "Untitled(1).docm" leads to Locky

This rather terse spam appears to come from the victim themselves (but doesn't). It has a malicious attachment.
From: recipient@victim.tld
To: recipient@victim.tld
Subject: Documents from work.
Date:    19 July 2016 at 12:20

What to do if you openen the attachment?

@Marja K - depends on your system settings. If you have allowed active content then the chances are that it will download and install ransomware. It should be pretty obvious if this has happened, but for one reason or another the infection doesn't always trigger.
