Malware spam: "Circor [_CIG-EDI@circor.com]" / "CIT Inv# 15000375 for PO# SP14161"

This fake finance spam pretends to be from the wholly legitimate firm Circor, but it is not. Instead, it is a forgery with a malicious Word document attached.

Don't be fooled by the email signature, the attachment is definitely nasty. So far I have only seen one version with a detection rate of 4/55, which contains a malicious macro [pastebin] that downloads a component from:


..which is then saved as %TEMP%\\dsfsdf.exe. This has a VirusTotal detection rate of 3/48 (it is identified as a Dridex component). According to the Malwr report, this phones home to a couple of IPs that I haven't seen before: (Universidade De Sao Paulo, Brazil) (MWTV SIA, Latvia)

It also drops a DLL with a detection rate of 3/56.
