Malware spam: "Second Reminder - Unpaid Invoice"

This fake financial spam leads to malware:

From:    Janis Faulkner [FaulknerJanis8359@ono.com]
Date:    29 April 2016 at 11:13
Subject:    Second Reminder - Unpaid Invoice

 We wrote to you recently reminding you of the outstanding amount of $8212.88 for Invoice number #304667, but it appears to remain unpaid.
For details please check invoice attached to this mail


Janis Faulkner
Chief Executive Officer - Food Packaging Company 

Attached is a ZIP file with a name similar to unpaid_invoice551.zip which contains a randomly-named script. Oddly, most of the script appears to be text copy-and-pasted from the Avira website.

The scripts I have seen download slightly different binaries from the following locations:


VirusTotal detection rates are in the range of 8/56 to 10/56 [1] [2] [3] [4]. In addition to those reports, various automated analyses [5] [6] [7] [8] [9] show that this is Locky ransomware phoning home to: (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua, Ukraine) (Park-web Ltd, Russia) (Relink Ltd, Russia) (Agava Ltd, Russia) (Relink, Russia / OVH, France)

I strongly recommend that you block traffic to:

Malware spam: "Attached Doc" / "Attached Image" / "Attached Document" / "Attached File"

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

Example subjects include:

Attached Doc
Attached Image
Attached Document
Attached File

Example senders:


There is no body text. Attached is a ZIP file with the recipients email address forming part of the name plus a couple of random numbers. These ZIP files contain a variety of malicious scripts, the ones that I have seen download a binary from:


The VirusTotal detection rate for the dropped binary is 3/55. That VirusTotal report and this Hybrid Analysis show subsequent traffic to:


The payload is Locky ransomware. This is hosted on what appears to be a bad server at: (Kyivstar GSM, Ukraine)

Kyivstar is a GSM network, something hosted on this IP is usually a sure sign of a botnet. A lookup of the giotuipo.at domain shows that it is multihomed on many IPs: (ER-Telecom Holding, Russia) (Sibirtelecom, Russia) (RCS & RDS Business, Romania) (Lanet Network Ltd, Ukraine) (Airbites, Ukraine) (Kyivstar, Ukraine) (Lanet Network Ltd, Ukraine) (Apex, Ukraine) (Triolan, Ukraine) (Triolan, Ukraine)

These IPs are likely to be highly dynamic, so blocking them may or may not work. If you want to try, here is a recommended blocklist:

Malware spam: "Royal Bancshares of Pennsylvania, Inc." / "Latest invoice [Urgent]"

This fake financial spam leads to malware:

From:    Kieth Valentine [Kieth.Valentine87@assistedlivingflorida.com]
Date:    28 April 2016 at 16:32
Subject:    Latest invoice [Urgent]


We are writing to you about fact, despite previous reminders, there remains an outstanding amount of USD 5883,16 in respect of the invoice(s) contained in current letter. This was due for payment on 17 April, 2016.

Our credit terms stipulate full payment within 3 days and this amount is now more than 14 days overdue.
The total amount due from you is therefore USD 5883,16

If the full amount of the sum outstanding, as set above, is not paid within 7 days of the date of this email, we will begin legal action, without warning, for a court order requiring payment. We may also commence insolvency proceedings. Legal proceedings can take affect on any credit rating. The costs of legal proceedings and any other amounts which the court orders must also be paid in addition to the debt.

This email is being sent to you according to the Practice Direction on Pre-Action Conduct (the PDPAC) contained in the Civil Procedure Rules, The court has the power to sanction your continuing failure to respond.

To view the the original invoice in the attachment please use Adobe Reader.

We await your prompt reaction to this email.

Best wishes,

The only sample I have seen of this is malformed and the attachment cannot be downloaded. However, what it should be in this case is a file Latest invoice18.zip containing a malicious script 2016INV-APR232621.pdf.js. Analysis of this obfuscated script is pending, it is likely to be either Locky ransomware or the Dridex banking trojan.

Malware spam: "FW: Invoice" from multiple senders

This fake financial spam comes from randomly-generated senders, for example:

From:    Britt Alvarez [AlvarezBritt29994@jornalaguaverde.com.br]
Date:    28 April 2016 at 11:40
Subject:    FW: Invoice

Please find attached invoice #342012

Have a nice day

Attached is a ZIP file containing elements of the recipient's email address. In turn, this contains a malicious script that downloads a binary from one of many locations. The ones I have seen are:


The payload looks like Locky ransomware. The DeepViz report shows it phoning home to: (Firstbyte, Russia) (Relink, Russia) (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine) (Relink, Russia / OVH, France) (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua.  Ukraine)

These two Hybrid Analysis reports [1] [2] show Locky more clearly.

Minimalist spam leads to Locky ransomware

There is currently a very minimalist spam run leading to Locky ransomware, for example:

From:    victim@victimdomain.tld
To:    victim@victimdomain.tld
Date:    28 April 2016 at 11:21
Subject:    Scan436
The spam appears to come from the victim's own email address. There is no body text, but attached is a ZIP file with a name matching the subject, e.g.:


Inside is a semi-randomly named script that downloads malware. Download locations I have seen so far are:


The downloaded executable is Locky ransomware and has a VirusTotal detection rate of 2/56. This Hybrid Analysis shows Locky quite clearly, and this DeepViz report shows it phoning home to: (Relink LLC, Russia / OVH, France) (Relink LLC, Russia) (Firstbyte, Russia)

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:


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:


This DeepViz report shows the malware phoning home to: (Digital Ocean, US) (Digital Ocean, Singapore) (Digital Ocean, Netherlands)

There's a triple whammy for Digital Ocean! Well done them.

Malware spam: "Missing payments for invoices inside"

Hi there!

Hope you are good.

Hope you are good. We're missing payments on our statements for the invoices included in this email. Please let us know, when the payments will be initiated.

BTW, trying to get reply from you for a long time. This is not junk, do not ignore it please.

I have only seen a single sample of this, it is likely that the company names and sender will vary. Attached is a file missing_quickbooks982.zip which contains a malicious obfuscated javascript 91610_facture_2016.js which attempts to download a component from:


This drops a file pretending to be favicon.ico which is actually an executable with a detection rate of 3/56. This Hybrid Analysis and this DeepViz report indicate network traffic to: (OrionVM Retail Pty Ltd, Australia) (Hetzner, Germany) (FPT Telecom Company, Vietnam) (EASY Net, Czech Republic)

The payload isn't exactly clear, but it looks like Dridex rather than Locky. Almost certainly one of the two.

Attached is a file with a name that matches the randomly-generated order (in this case, ORDER-525-2814418-9619799.docm). According to analysis by a couple of other trusted parties, the various versions of the malicious document download a binary from:


This dropped executable has a detection rate of 6/56. The Hybrid Analysis and DeepViz Analysis plus some data sourced from other parties (thank you) indicates that the malware calls back to the following IPs: (Redfox Telecomunicações Ltda., Brazil) (MultiNet AS, Norway) (Topix, Italy) (Novanet da Barra Ass e Inf LTDA, Brazil)

The payload here appears to be the Dridex banking trojan.

UPDATE 2016-04-26

Another identical round of this spam is being sent out, complete with the formatting error that prevents the body text being displayed on some email clients. VirusTotal detection rates for the two samples I have seen are 5/57 [1] [2]. Hybrid Analysis of the attachments [3] [4] shows download locations at:


A trusted source tells me there are other download locations at:


From here a binary is dropped on the system with a detection rate of 3/56. Those Hybrid analyses plus this DeepViz report show network traffic to: (Hetzner, Germany)

Malware spam: "FW: Latest order delivery details" is somewhat rude

From:    Milan Bell [Milan.Bell5@viuz-en-sallaz.fr]

Subject:    FW: Latest order delivery details

Good morning!

Hope you are good.

Yesterday and the day before my colleague (Glover Hector) sent you a request regarding the invoice INV_6325-2016-victimdomain.tld past due.

I kindly ask you to give us a reply finally. We're getting no answers from you. Please stop ignoring invoice requests.

Many thanks and good luck

The rather rude pitch here is a canny bit of social engineering, aimed to make you open the link without clicking. I have only seen one sample of this at present and I guess that the details vary from email to email. In this case the attachment was called pastdue_tovictimdomain.tld340231.zip containing a malicious script pastdue60121342016.js.

This script has a VirusTotal detection rate of just 1/56. The Malwr report and Hybrid Analysis for this show it downloading a malicious binary from:


Cheekily the URL references a well-known security company.  The domain it is using is a hijacked GoDaddy domain, and the download location is actually hosted at: (PE Ivanov Vitaliy Sergeevich / Xserver.ua, Ukraine)

You can be that this is a malicious server and I recommend blocking it. This script downloads a binary named alarm.exe which has a detection rate of 4/56. The Hybrid Analysis for this sample shows network connections to: (OrionVM, Australia) (Hetzner, Germany) (PT Telecom Company, Vietnam) (Datacate , US)

It is not clear what the payload is, but there are indications it is the Dridex banking trojan.
