Malware spam: Scanned image from copier@victimdomain.tld

This fake document scan appears to originate from within the victim's own domain, but it doesn't. Instead this is a simple forgery with a malicious attachment.

I have seen two different versions of the attached document, named in a format copier@victimdomain.tld_20160129_084903.doc. The detection rate for both is 6/54 [1] [2] and the Malwr report for one of them shows the macro downloading from:

dulichando.org/u56gf2d/k76j5hg.exe

This executable has a detection rate of 4/53 and the Hybrid Analysis reports that it phones home to:

185.24.92.236 (System Projects LLC, Russia)

I strongly recommend that you block traffic to that IP. The payload is Dridex, as seen here.
