Malware spam: "Following the phone conversation with the accounting department represantatives I'm sending you the invoices."

These fake financial spams come from different companies, all with a malicious attachment.

Subject:    The invoices from INCHCAPE PLC


Hello,
Following the phone conversation with the accounting department represantatives I'm sending you the invoices.

Thank you for attention,
Kind regards

Attached is a ZIP file with a name similar to Invoice 5044-032841.zip which in turn contains a malicious script named in a similar manner to invoice(677454).js which typically has a detection rate of 3/56. Hybrid Analysis of that sample shows the script creating a PFX (personal certificate) file which is then transformed into a PIF (executable) file using the certutil.exe application.

This PIF file itself has a detection rate of 6/56 but automated analysis [1] [2] [3] is inconclusive. The behaviour is somewhat consistent with the Dridex banking trojan but may possibly be Locky ransomware.

In the two samples I have seen, there are attachments named Security Report.zip and Security Notification.zip which in turn contain a Word document with a name such as Security Report ID(11701573).doc

The two documents that I have seen have detection rates of about 3/56 [1] [2] but according to these automated analyses [3] [4] [5] [6] it seems that the infection doesn't work properly, failing to find a created file harakiri.exe. This Malwr report shows a dropped file named harakiri.pfx which isn't an executable, my guess is that this is an encrypted file that hasn't decrypted properly.

UPDATE

According to a third party analysis, this apparently drops Dridex which phones home to:

210.245.92.63 (FPT Telecom Company, Vietnam)
162.251.84.219 (PDR Solutions, US)
80.88.89.222 (Aruba, Italy)

Malware spam: "Please See Attached" / "Statement 6BBC0E"

This fake financial spam leads to malware. Details change slightly from email to email:

From:    Administrator [adminHb@victimdomain.tld]
Date:    5 May 2016 at 11:29
Subject:    Statement 6BBC0E

Please See Attached

It must be safe.. scanned by both Symantec and Avast! Well, of course that's just BS and the attached DOC file leads to malware, specifically the same payload as seen in this slightly earlier spam run.

Malware spam: "DocuCentre-IV" / "Scan Data"

This fake document scan appears to come from within the victim's own domain (but this is just a simple forgery) and has a malicious attachment:

Number of Images: 1
Attachment File Type: PDF

----=_Part_45251_4627454344.4826709420825--

Details vary slightly from message to message. Attached is a DOC file (not a PDF) starting with PIC, DOC or IMG in the samples I have seen plus a random number. Typical VirusTotal detection rates are 6/56 [1] [2] [3] [4] [5] [6]. Various automated analyses of these documents [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] show a binary being downloaded from the following locations:

fm1.ntlweb.org/87hcnrewe
iconigram.com/87hcnrewe
www.sammelarmband.de/87hcnrewe
hospice.psy.free.fr/87hcnrewe


This dropped file has a detection rate of 5/46. This Hybrid Analysis and this DeepViz report show subsequent network traffic to:

192.241.252.152 (Digital Ocean, US)
195.169.147.26 (Culturegrid.nl, Netherlands)
70.164.127.132 (Southland Technology, US)


The characteristics of the payload suggest this is the Dridex banking trojan.

Malware spam: "Missing payments for invoices inside"

This fake financial spam leads to malware:

Subject:    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:

web.spartanburgcommunitycollege.com/gimme/some/loads_nigga.php

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:

103.245.153.154 (OrionVM Retail Pty Ltd, Australia)
176.9.113.214 (Hetzner, Germany)
210.245.92.63 (FPT Telecom Company, Vietnam)
213.192.1.171 (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:

194.116.73.71 (Topix, Italy)

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:

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:

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

This fake financial spam leads to malware:

From:    Milan Bell [Milan.Bell5@viuz-en-sallaz.fr]
Date:    21 April 2016 at 17:45
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:

trendmicro.healdsburgdistricthospital.com/RIB/assets.php

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:

176.103.56.30 (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:

103.245.153.154 (OrionVM, Australia)
176.9.113.214 (Hetzner, Germany)
210.245.92.63 (PT Telecom Company, Vietnam)
23.249.1.171 (Datacate , US)


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

This script has a typical detection rate of 8/56.

So far I have seen two versions of this script, downloading from:

mountainworldtreks.com/9uhg5vd3

This malicious script [pastebin] downloads an executable from:

Malware spam: "Prompt response required! Past due inv. #FPQ479660" / "Jake Gill"

This fake financial spam has a malicious attachment:

From:    Hillary Odonnell [Hillary.OdonnellF@eprose.fr]
Date:    13 April 2016 at 18:40
Subject:    Prompt response required! Past due inv. #FPQ479660

Hello,

I am showing that invoice FPQ479660 is past due. Can you tell me when this invoice is scheduled for payment?

Thank you,

Jake Gill

The person it is "From", the reference nu,ber and the company name vary from spam to spam. All the samples I have seen have the name "Jake Gill" in the body text. Attached is a semi-random RTF document (for example, DOC02973338131560.rtf).

There seem to be several different versions of the attachment, I checked four samples [1] [2] [3] [4] and VirusTotal detection rates seem to be in the region of 7/57. The Malwr reports for those samples are inconclusive [5] [6] [7] [8] (as are the Hybrid Analyses [9] [10] [11] [12]) but do show a failed lookup attempt for the domain onlineaccess.bleutree.us (actually hosted on 212.76.140.230 - MnogoByte, Russia). The payload appears to be Dridex.

We can see a reference to that server at URLquery which shows an attempted malicious download. It also appears in this Hybrid Analysis report. At the moment however, the server appears to be not responding, but it appears that for that sample the malware communicated with:

195.169.147.88 (Culturegrid.nl, Netherlands)
178.33.167.120 (OVH, Spain)
210.70.242.41 (TANET, Taiwan)
210.245.92.63 (FPT Telecom Company, Vietnam)


These are all good IPs to block.

According to DNSDB, these other domains have all been hosted on the 212.76.140.230 address:

onlineaccess.bleutree.com
egotayx.net
wgytaab.net
emoaxmyx.net
wmbyaxma.net
emeotalyx.net
ezhoyznyx.net
wmeybtala.net
wzhybyzna.net
onlineaccess.bleutree.info

You can bet that they are all malicious too.

Malware spam: "Proof of Delivery Report: 16/03/16-17/03/16" / UKMail Customer Services [list_reportservices@ukmail.com]

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

At the time of writing I have seen just a single sample with an attachment named poddel-pdf-2016031802464600.docm which has a VirusTotal detection rate of 9/55. This Malwr report for the sample shows a file download from:

kervanburak.com/wp-content/plugins/hello123/r34t4g33.exe

There will be many other versions of the attachment with different download locations. This binary has a detection rate of 8/55 and this Malwr report and Hybrid Analysis  show network traffic to:

64.147.192.68 (Dataconstructs, US)

I recommend you block traffic to that IP. The payload appears to be the Dridex banking trojan.

Malware spam: "Remittance Adivce" from random senders

This fake financial spam has a malicious attachment and poor spelling in the subject field.

From:    Booth.Garth19@idsbangladesh.net.bd
Date:    17 March 2016 at 09:17
Subject:    Remittance Adivce


Please find attached a remittance advice for payment made yo you today.

Please contact the accounts team on 020 2286 7847 or via reply email for any queries regarding this payment.

Kind Regards

Sender names, contact number and attachment names vary, but I have seen just a single variant of the attachment with a VirusTotal detection rate of 1/55. The Malwr report for this sample sees a download from:

bakery.woodwardcounseling.com/michigan/map.php

This download location is almost certainly completely malicious, and is hosted at:

217.12.199.94 (ITL, Ukraine)

This dropped file has a detection rate of 3/56. That VirusTotal and this Malwr report indicate network traffic to:

38.64.199.33 (PSINet, Canada)
188.93.239.28 (DotSi, Portugal)


The payload is uncertain, but it could be the Dridex banking trojan.

UPDATE

The DeepViz analysis  also shows traffic to:

85.17.155.148 (Leaseweb, Netherlands)

Your Interparcel collection has been booked and your documents are ready.

There is a document attached to this email called Shipping Labels (620486055838).doc.
Please open and print this attachment and cut out the waybill images. They must be attached to your parcels before the driver arrives.

Thank you for booking with Interparcel.
Attached is a randomly-named document that matches the reference in the email (e.g. Shipping Labels (620486055838).doc) of which I have seen two variants (VirusTotal results [1] [2]). These two Malwr reports [3] [4] show Dridex-like download locations at:

ziguinchor.caravanedesdixmots.com/wp-content/plugins/hello123/56h4g3b5yh.exe


The detection rate for the binary is 5/57. This DeepViz report on the binary shows network connections to:

195.169.147.26 (Culturegrid.nl, Netherlands)
64.76.19.251 (Level 3, US / Impsat, Argentina)
91.236.4.234 (FHU Climax Rafal Kraj, Poland)

There are no doubt several other download locations. This binary has a detection rate of 3/56. The various reports indicate that it phones home to a server at:

Malware spam: "Remittance" from random companies with .rtf attachment

This fake financial spam appears to come from random companies. The body text is similar in call cases.

Sample 1:
From:    Ignacio - Floris of London
Date:    4 March 2016 at 09:42
Subject:    Remittance


Dear Sir/Madam,

I hope you are well. I am writing you to let you know that total amount qualified in the contract has been sent to your bank account on the 3rd of March at 14 through BACS payment system and should reach the destination (beneficiary's) account within 3 working days.
To see full payment details please refer to the remittance advice note attached to the letter.

Any queries? Please reply back with your questions and you will receive a prompt and qualitative response as soon as possible. Please do not hesitate to write us.

Ignacio Knox
Accounts Payable

Sample 2:

From:    Audra - ECLECTIC BAR GRP PLC
Date:    4 March 2016 at 09:48
Subject:    Remittance

Dear Sir/Madam,

Hope you are OK. I am writing you to let you know that entire amount specified in the contract has been paid into your bank account on the 1st of March at 16 over BACS payment system and should reach the destination (beneficiary's) account within 3 working days.
To see full payment details please refer to the remittance advice note in the attachment.

Any queries? Please reply back with your questions and you will receive a prompt and qualitative response as soon as possible. Please do not hesitate to write us.

Audra Pratt
Accounts Payable

Attached is a file named in a format similar to rem.advice-6430760513.rtf or invoice-9200564788.rtf. Detection rates are pretty low [1] [2] [3] and the Malwr reports are inconclusive [4] [5] [6] although I suspect the attachment itself may be malformed. Further analysis is pending.

UPDATE

These Hybrid Analysis reports  [1] [2] [3] show the file downloading a malicious binary from one of the following fruit-flavoured domains:

wildberry.markettimingintelligence.com/zalupa/kurva.php
raspberry.diversified-capital-management.com/zalupa/kurva.php

This file is dropped as %TEMP%\sdjgbcjkds.exe and both those sites are hosted on:

31.131.24.76 (PE Skurykhin Mukola Volodumurovuch, Ukraine)

Along with another domain of strawberry.reactionpointtimingindicator.com. All of these are hijacked GoDaddy domains.

The Malwr report for the executable shows it communicating with:

24.172.94.181 (Time Warner, US)

This is the same IP as seen here which Sophos identified as being Dridex.  

Recommended blocklist:
31.131.24.76
24.172.94.181
