Malware spam: "I have shipped your packet. Please check the report enclosed here to view more info."

This spam email leads to Cerber ransomware:

From:    Trevor David
Date:    3 October 2016 at 13:46
Subject:    Pede Industries

Hello
I have shipped your packet. Please check the report enclosed here to view more info.

Word doc password: JqpcGrKK9


Pede Industries
Company names and senders are randomly generated. Attached is a randomly-named .DOT file with password protection. The password protection makes it hard to analyse, but my source tell me that these documents download from:

www.ldlogistic.it/kls.doc
csir.bdx6.siteinternet.com/kls.doc

The dropped malware apparently has an MD5 of 0e7913875724151d8e822add07ec75b2.

Once downloaded, the malware attempts to make a C2 connection to an IP in the range
31.184.234.0/23:6892 (GTO, Montenegro and Virty.io, Russia). I don't know which is the active IP, but blocking the entire /23 might be a good precaution.

Malware spam: "[Scan] 2016-1003 15:26:26" / "Sent with Genius Scan for iOS." leads to Locky

This fake document scan leads to Locky ransomware:

Subject:    [Scan] 2016-1003 15:26:26

Sent with Genius Scan for iOS.
The name of the sender, the subject and the attachment name (in this case 2016-1003 15-26-26.xls) will vary somewhat.

This Malwr analysis shows some of the infection in action. Overall my sources tell me that the various malicious macros download from:

Malware spam: "please sign" leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     please sign
From:     Ricardo Buchanan
Date:     Monday, 3 October 2016, 10:27

Hi [redacted],

I have made the paperwork you asked me to prepare two days ago.
Please check the attachment. It just needs your signature.



Best Wishes,
Ricardo Buchanan
CEO
In the only sample I have seen so far, the attachment name is paperwork_scan_7069f18e6.zip containing a malicious script paperwork scan ~1EB91.wsf plus a junk file with a single letter name. This obfuscated script [pastebin] appears to download Locky ransomware. Analysis is pending.

UPDATE

This Hybrid Analysis clearly shows Locky in action. According to my sources there are no C2s, and the download locations are:

Malware spam: "Receipt 103-526" / Receipt.xls

This spam leads to Locky ransomware:

From     rosalyn.gregory@gmail.com
Date     Thu, 29 Sep 2016 21:07:46 +0800
Subject     Receipt 103-526
I cannot tell if there is any body text, however there is an attachment Receipt.xls which contains malicious code [pastebin] that in the case of the sample I analysed downloads a binary from:

opmsk.ru/g76ub76

There will be many other download locations too. Automated analysis [1] [2] shows that this is Locky ransomware phoning home to:

89.108.83.45/apache_handler.php (Agava, Russia)
91.200.14.93/apache_handler.php [hostname: ef4bykov.example.com] (SKS-LUGAN, Ukraine)
xpcwwlauo.pw/apache_handler.php [hostname: vjc.kz] [91.234.33.132] (FOP Sedinkin Olexandr Valeriyovuch aka thehost.ua, Ukraine)

A malicious DLL is dropped with a detection rate of 6/57. Malicious IPs and domains overlap quite a bit with this earlier attack. This version of Locky encrypts files with a .odin extension.

UPDATE - a source indicates these are all the download locations in this attack:

Malware spam: "Temporarily blocked" leads to Locky

The attachment on this spam email leads to Locky ransomware:

From: "Ambrose Clements"
Subject: Temporarily blocked
Date: Thu, 29 Sep 2016 13:37:53 +0400

Dear [redacted]

this is to inform you that your Debit Card is temporarily blocked as there were unknown transactions made today.

We attached the scan of transactions. Please confirm whether you made these transactions.
 Attached is a ZIP file with a name similar to debit_card_93765d0d7.zip containing a malicious .WSF script with a random name. These scripts (according to my source) download from one of the following locations:
