Attached is a  randomly-named ZIP file (e.g. 053324_00238.zip) which contains a malicious script (e.g. 0061007_009443.js). The samples I have seen download a binary from:

mebdco.com/8759j3f434
amwal.qa/8759j3f434
ecmacao.com/8759j3f434
lifeiscalling-sports.com/8759j3f434

This drops a version of what appears to be Locky ransomware with a detection rate of zero. I know from another source, that these additional download locations were being used for an English-language spam run this afternoon:

Thanks to analysis from a trusted source (thank you!) it appears that there are several scripts, downloading a binary from one of the following locations:

This downloads Locky ransomware. The executable then phones home to the following servers:

Malware spam: "Document from AL-KO" / info@alko.co.uk

This spam does not come from AL-KO but is instead a simple forgery with a malicious attachment:

From     [info@alko.co.uk]
Date     Thu, 05 Nov 2015 16:33:40 +0530
Subject     Document from AL-KO

This document is DOC created by Osiris OSFAX(R) V3.5.
It can be viewed and printed with Microsoft Word(R)

Document from AL-KO.doc

Attached is a file Document from AL-KO-01.doc which probably comes in many different versions, but I've only had the chance to run two through analysis. Both are undetected by any AV vendor [1] [2] at present. The structure of the document seems unusual and I am having some difficulties seeing the malicious macros, but these two Hybrid Analysis reports [3] [4] show the macro in action, downloading from:

members.dodo.com.au/~mfranklin17/f75f9juu/009u98j9.exe
www.mazzoni-hardware.de/f75f9juu/009u98j9.exe

There will be other locations too, all downloading the same binary with a detection rate of 4/54 (MD5 39f7827813ac9bc74a4a9176c9e80487) Other automated analyses [5] [6] show network traffic to:

128.199.122.196 (Digital Ocean, Singapore)
75.99.13.123 (Cablevision, US)

The payload appears to be the Dridex banking trojan.

Attached is a pdf file containing items that have shipped
Please contact us if there are any questions or further assistance we can provide

Attached is a file Advance Shipping Notification 0068352929.DOC which my sources (thank you, btw) say comes in four different versions, although I have only seen three (VirusTotal results [1] [2] [3], Hybrid Analysis results [4] [5] [6])  containing a macro that looks like this [pastebin]. The download locations are:

This malicious binary has a VirusTotal detection rate of 6/54. That VT report and this Hybrid Analysis report show network communications to the following IPs:

128.199.122.196 (Digital Ocean, Singapore)
75.99.13.123 (Cablevision, US)
198.74.58.153 (Linode, US)

Attached is a file PORDER.DOC which comes in three different versions (although I only have two samples [1] [2]) containing a malicious macro similar to this one [pastebin], which download a binary from the following locations:

This binary has a detection rate of 4/55 and according that that VirusTotal report, this reverse.it report this Malwr report it contacts the following IP:

I strongly recommend that you block that IP. The payload is likely to be the Dridex banking trojan.

Malware spam: "Documents for Review and Comments" / Pony / eyeseen.net

This fake document scan email has a malicious attachment:

Hi Morning,

Attached are the return documents.

Call me if you need anything.

See you soon. :)

The attached file is SCANNED DOCS,jpg.z which is a type of compressed file. If you have the right file decompression software, it will extact a malicious executable SCANNED DOCS,jpg.exe which has a VirusTotal detection rate of 17/55.

According to various automated analysis tools [1] [2] [3] it drops a file %TEMP%\XP000.TMP\M.exe which itself has a detection rate of 19/54. Out of all the standard analysis tools I have used, only Comodo CAMAS identified the network traffic, a POST to:

eyeseen.net/swift/gate.php

This is hosted on a SoftLayer IP of 198.105.221.5 in Singapore. A quick look at VirusTotal indicates a lot of badness on this IP address, so it is probably one worth blocking.

The payload is Pony / Fareit, which is basically a password stealer.

The "Subject" is the victim's own email address. Attached is a file FINAL NOTIFICATION.xls which comes (so far) in three different variants (VirusTotal [1] [2] [3]) contains one of these three malicious macros [1] [2] [3] .

Analysis of the payload is pending, but is likely to be the Dridex banking trojan. Please check back later.

I recommend that you block traffic to that IP.

Running in parallel to this is another claiming to be from UK firm AquaAid which has been going on for a long time. In the first case the attachment is 20150326094147512.doc and in the second it is CAR015890001.doc, but they are the same malicious document.

The document is currently undetected by AV vendors and contains a malicious macro [pastebin] which downloads a binary from:

Attached is a zip file in the format Voice_Mail_recipientname.zip which in turn contains a malicious file Voice_Mail.exe which has an icon to make it look like an audio file. VirusTotal detection for that is 7/47 and automated analysis tools [1] [2] show an attempted connection to amazingfloorrestoration.com on 202.150.215.66 (NewMedia Express, Singapore). Note that sometimes other sites on these servers have also been compromised, so if you see any odd traffic to this IP then it could well be malicious.
