Malware spam: "Per E-Mail senden: DOC0000329040"

This German-language spam comes with a malicious attachment. It appears to come from the victim themselves, but this is just a simple forgery.

Attached is a ZIP file that matches the reference number in the subject and body text. I have only seen one sample, downloading a binary from:

katyco.net/0uh8nb7

The VirusTotal detection rate is 4/57, the comments in that report indicate that this is Locky ransomware and the C&C servers are at:

Malware spam: "I have attached a revised spreadsheet.."

This spam has a malicious attachment:

From:    Britney Hart
Date:    16 May 2016 at 13:15
Subject:    Re:

hi [redacted]

I have attached a revised spreadsheet contains customers. Please check if it's correct

Regards,
Britney Hart

Other variations of the body text seen so far:

I have attached a revised spreadsheet contains general journal entries. Please check if it's correct
I have attached a revised spreadsheet contains estimates. Please check if it's correct


Attached is a ZIP file with three identical malicious .js files. The ones I have seen so far download from

fundaciontehuelche.com.ar/897kjht4g34
thetestserver.net/fg45g4g
technobuz.com/876jh5g4g4


There are probably other download locations. Each one downloads a slightly different binary (VirusTotal prognosis [1] [2] [3]) and automated analysis [5] [6] [7] [8] [9] shows the malware phoning home to:

188.127.231.124 (SmartApe, Russia)

Malware spam: Emailing: Photo 05-11-2016, 03 26 04

This spam comes with a malicious attachment:

From:    victim@victimdomain.tld

Note: To protect against computer viruses, e-mail programs may prevent
sending or receiving certain types of file attachments.  Check your e-mail

It appears to come from the sender's own email address, but this is a simple forgery (explained here). Attached is a ZIP file with a name similar to Photo 05-11-2016, 03 26 04.zip (the numbers in the attachment
match the references in the email). It contains a .js file with a similar name.

Malware spam: "As promised, the document you requested is attached" leads to Locky

This fairly brief spam has a malicious attachment:

From:    Alexandra Nunez
Date:    10 May 2016 at 21:10
Subject:    Re:

hi [redacted],

As promised, the document you requested is attached

Regards,

The name of the sender varies. Attached is a ZIP file with a name export_xls_nnn.zip or wire_xls_nnn.zip (where nnn are random letters and numbers) which contains multiple copies of the same malicious .js file (all apparently beginning urgent). These scripts download slightly different binaries from several locations including:


4hotdeals.com.au/j47sfe
stationerypoint.com.au/cnb3kjd
floranectar.com.au/er5tsd
togopp.com/vbg5gf
printjuce.com/rt5tdf
designitlikeal.com/cvb3ujd


There are probably many more download locations.

The typical detection rate for these binariesis about 12/56 [1] [2] [3] [4] [5] and automated analysis [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] shows network traffic to:

Malware spam: "Third Reminder - Outstanding Account" leads to Locky

This fake financial spam has a malicious attachment. It comes from random senders. Last week a fake "Second Reminder" spam was sent out.

From:    Ernestine Perkins
Date:    3 May 2016 at 08:54
Subject:    Third Reminder - Outstanding Account

 Dear Client,

We have recently sent you a number of letters to remind you that the balance of $9308.48 was overdue.
For details please check document attached to this mail


We ask again that if you have any queries or are not able to make full payment immediately, please contact us.


Regards,

Ernestine Perkins
Franchise - Sales Manager / Director - Business Co 

Attached is a ZIP file which in the samples I have seen begins with Scan_ or Document_ each one of which contains four identical copies of the same script, e.g.:

48524088_48524088 - copy (2).js
48524088_48524088 - copy (3).js
48524088_48524088 - copy (4).js
48524088_48524088 - copy.js
48524088_48524088.js


Typical detection rates for the scripts seem to be about 3/56.  The samples I have seen download a malicious binary from one of the following locations (there are probably more):

digigoweb.in/k3lxe
rfacine.com.br/z0odld
boontur.com/b2hskde


These binaries are all slightly different, with detection rates of 4 to 6 out of 56 [1] [2] [3]. Various automated analyses [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] show that this is Locky ransomware, and it phones home to:

31.184.197.126 (Petersburg Internet Network, Russia)

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

Regards,

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:

cafeaparis.eu/f7yhsad
amatic.in/hdy3ss
zona-sezona.com.ua/hj1lsp
avcilarinpazari.com/u7udssd


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:

91.234.32.19 (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua, Ukraine)
83.217.8.155 (Park-web Ltd, Russia)

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:

epson@victimdomain.tld
scanner@victimdomain.tld
xerox@victimdomain.tld

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:

emcartaz.net.br/08j78h65e
kizilirmakdeltasi.net/08j78h65e
easytravelvault.com/08j78h65e
64.207.144.148/08j78h65e
cdn.cs2.pushthetraffic.com/08j78h65e


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

giotuipo.at/api/
giotuipo.at/files/dDjk3e.exe
giotuipo.at/files/VTXhFO.exe


The payload is Locky ransomware. This is hosted on what appears to be a bad server at:

134.249.238.140 (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:

109.194.247.26 (ER-Telecom Holding, Russia)
95.189.128.70 (Sibirtelecom, Russia)
79.119.196.161 (RCS & RDS Business, Romania)
5.248.229.186 (Lanet Network Ltd, Ukraine)
188.230.17.38 (Airbites, Ukraine)
134.249.238.140 (Kyivstar, Ukraine)
5.58.29.200 (Lanet Network Ltd, Ukraine)
212.3.103.225 (Apex, Ukraine)
93.95.187.243 (Triolan, Ukraine)
178.151.243.153 (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:

109.194.247.26

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:

http://rabitaforex.com/pw3ksl
http://tribalsnedkeren.dk/n4jca
http://banketcentr.ru/v8usja
http://3dphoto-rotate.ru/h4ydjs
http://switchright.com/2yshda
http://cafe-vintage68.ru/asad2fl
http://minisupergame.ru/a9osfg


The payload looks like Locky ransomware. The DeepViz report shows it phoning home to:

83.217.26.168 (Firstbyte, Russia)
31.41.44.246 (Relink, Russia)
91.219.31.18 (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)
51.254.240.60 (Relink, Russia / OVH, France)
91.234.32.19 (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua.  Ukraine)

91.234.32.19

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.:

file238.zip
file164.zip
file84.zip
Document4.zip
Doc457.zip
Scan1.zip
Doc5.zip
file394.zip
Scan436.zip

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

nailahafeez.goldendream.info/8778h4g
kfourytrading.com/8778h4g
kasliknursery.com/8778h4g
allied.link/8778h4g
xtrategiamx.com/8778h4g


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:

51.254.240.60 (Relink LLC, Russia / OVH, France)
31.41.44.246 (Relink LLC, Russia)
83.217.26.168 (Firstbyte, Russia)

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

Accounts Receivable Department

Diploma plc

(094) 426 8112
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
onlineaccess.bleutree.mobi


You can bet that they are all malicious too.

Fake boss scams meet AI robocallers in a dangerous escalation of fraud

Many of us will be familiar with the "fake boss" scam. You're sitting at your desk when your CEO suddenly calls and asks you to transfer a large stack of currency to some shady bank account for a business transaction you are not allowed to talk about.

This type of fraud is simple and can often pay out big bucks, but it is also labour intensive. Research has to be done on companies and convincing calls have to be made to unsuspecting minions. Not only does this all take some time, but the more people involved in the scam then the more ways you have to split the booty.. and the greater the change of getting caught.

Now, the notorious Russian gang dubbed Den Duraka by researchers have been discovered using a cunning new technique which makes this type of attack even more dangerous. Instead of relying on human beings to make the phone calls, they have now enrolled an AI-powered robocalling system called which promises to be a game-changer.

Sporting the clumsy Russian acronym LOZHNYY, this is deeply integrated into LinkedIn, Facebook, Twitter and other social networks, with feeds into business directories using hacked credentials. Once it has found a CEO to impersonate, it scours the web for video and audio clips to get an idea of accents and mannerisms, and then it starts to research company filings and financial data. All of this is then combined with a wide range of pre-prepared scripts and some basic question-and-answer scenarios to make a deadly weapon in the hands of the scammers.

Some of the conversational AI features are rudimentary, and LOZHNYY sometimes resorts to buzzword-laden nonsense when out of its depth. Victims report that they were not suspicious as this seemed consistent with the behaviour of their CEOs.

Cybersecurity experts are struggling with ways to counter this new threat. At the moment their best advice is to completely ignore any communications from your CEO and indeed any C-level executive. You have been warned!

(If you hadn't spotted the clues in the Russian names above.. this is an April Fools joke)

Malware spam: "Additional Information Needed #869420" leads to ransomware

This spam has a malicious attachment, leading to ransomware.

From:    Joe holdman [holdmanJoe08@seosomerset.co.uk]
Date:    30 March 2016 at 08:55
Subject:    RE: Additional Information Needed #869420


We kindly ask you to provide us additional information regarding your case.
Please find the form attached down below.
The reference number varies in the subject. The attachment is a ZIP file containing elements of the recipients email address and words like "copy" or "invoices" plus a random number. These unzip into a folder called "letter" to give a .js file beginning with "letter_" and a .wrn file which also appears to be a script but which won't run by default.

An analysis of three scripts [1] [2] [3] shows binary downloads from:

cainabela.com/zFWvTM.exe
downloadroot.com/vU4VAZ.exe
folk.garnet-soft.com/jDFXfL.exe

This binary has a detection rate of 6/56.  Automated analysis [4] [5] shows network traffic to:

93.170.131.108 (Krek Ltd, Russia)
5.135.76.18 (OVH, France / Bondhost, Montenegro)
82.146.37.200 (TheFirst-RU, Russia)

Malware spam: "CCE29032016_00034" / "Sent from my iPhone"

The malware spammers have been busy again today. I haven't had time to look at this massive spam run yet, so I am relying on a trusted third party analysis (thank you!)

These spam emails look like the victim is sending them to themselves (but they aren't). Reference numbers vary a little between emails, but the basic pattern is:

From:    victim
To:    victim
Date:    29 March 2016 at 17:50
Subject:    CCE29032016_00034

Sent from my iPhone

Attached is a RAR archive with a name that matches the subject (e.g. CCE29032016_00034.rar) and this contains a malicious .js file that leads to Locky ransomware. My contact tells me that the download locations in the scripts are:

This payload has a detection rate of 4/56. The malware calls back to:

84.19.170.249 (Keyweb, Germany / 300GB.ru, Russia)
5.135.76.18 (OVH, France / Bondhost, Montenegro)
109.234.35.128 (McHost, Russia)


McHost is almost purely a black-hat ISP in my opinion and should be blocked on sight.

All of those look like pretty shady neigbourhoods, although I haven't examined them closely at this point. The payload is the Locky ransomware.

The other binary appears to be another version of Locky which appears to phone home to the same servers.

Malware spam: "FX Service" / "Fax transmission" spoofing victim's domain

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

From:    FX Service [emailsend@w.e191.victimdomain.tld]
Date:    21 March 2016 at 14:32
Subject:    Fax transmission: -7172277033-1974602246-2016032111285-47417.tiff

Please find attached to this email a facsimile transmission we
have just received on your behalf

(Do not reply to this email as any reply will not be read by
a real person)
Details will vary from message to message. Attached s a ZIP file with a name that broadly matches the one referred to in the subject (e.g. F-7172277033-1974602246-2016032111285-47417.zip) which contains any one of a wide number of malicious scripts (some example VirusTotal results [1] [2] [3] [4] [5]). Malwr analysis of those samples [6] [7] [8] [9] [10] shows binary download locations at:

http://modaeli.com/89h766b.exe
http://spormixariza.com/89h766b.exe
http://sebastiansanni.org/wp-content/plugins/hello123/89h766b.exe
http://cideac.mx/wp-content/plugins/hello123/89h766b.exe


There are probably other download locations too. The dropped binary has a VirusTotal detection rate of just 2/56.  This Malwr report of the payload indicates that it is Locky ransomware.

All of those sources plus this Deepviz report show network traffic to the following IPs:

195.64.154.126 (Ukrainian Internet Names Center, Ukraine)
92.63.87.106 (MWTV, Latvia)
84.19.170.244 (Keyweb AG, Germany / 300GB.ru, Russia)

Malware spam: "Documentxx" apparently coming from the victim leads to Locky

This spam appears to come from the victim, but this is just a simple forgery (explained here). Attached is a ZIP file beginning "Document" followed by a one or two digit random number, which matches the subject. There is no body text. Here is an example:
From:    victim@domain.tld
To:    victim@domain.tld
Date:    17 March 2016 at 10:37
Subject:    Document32
Inside is a randomly-named script (samples VirusTotal reports [1] [2] [3] [4] [5] [6] [7]). These Malwr reports [8] [9] [10] [11] [12] [13]  indicate that the script attempts to download a binary from the following locations:

bezerraeassociados.com.br/wp-content/plugins/hello123/89h8btyfde445.exe


The dropped binary has a detection rate of just 2/57. Those reports and these other automated analyses [14] [15] [16] show network traffic to:

188.127.231.116 (SmartApe, Russia)
195.64.154.114 (Ukrainian Internet Names Center, Ukraine)


This is Locky ransomware.

Malware spam: "Credit details ID: 87320357" leads to Teslacrypt

So many Teslacrypt campaigns, so little time... I've had to rely on third party analysis on this particular one (thank you!)
From:    Ladonna feather
Date:    14 March 2016 at 14:50
Subject:    Credit details ID: 87320357

Your credit card has been billed for $785,97. For the details about this transaction, please see the ID: 87320357-87320357 transaction report attached.

5.166.207.194 (ER-Telecom Holding, Russia)
46.172.219.246 (Krym Infostroy Ltd, Ukraine)

Out of these, only the first three (for giveitallhereqq.com) appear to be static IPs, the others (for washitallawayff.com) are dynamic and are likely part of a botnet, so blocking the domain might be better.

Malware spam: "Urgent Notice # 78815053" leads to Teslacrypt

This spam comes from random senders, and has random references, dollar amounts and attachment names:

From:    Donnie emily
Date:    12 March 2016 at 14:01
Subject:    Urgent Notice # 78815053

Dear Customer!

According to our data you owe our company a sum of $452,49. There are records saying that you have ordered goods in a total amount of $ 452,49 in the third quarter of 2015.

Invoice has been paid only partially. The unpaid invoice #78815053 is enclosed below for your revision.

We are writing to you, hoping for understanding and in anticipation of the early repayment of debt.

Please check out the file and do not hesitate to pay off the debt.

Otherwise we will have to start a legal action against you.

Regards,
Donnie emily

Attached is a randomly-named ZIP file, in the sample I have seen they begin with:
  • letter_
  • confirm_
  • access_
  • unconfirmed_operation_
  • operation_
  • details_
..plus a random number. There may be other formats. Inside is a malicious script beginning with:
  • details_
  • post_
  • mail_
..plus a random string of characters. I have seen six versions of this script, I do not know how many there are in total. VirusTotal results show detection rates between 4 and 7 out of 57 [1] [2] [3] [4] [5] [6] and automated analysis tools [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] show the script attempting to download a binary from:

bonjovijonqq.com/69.exe?1
bonjovijonqq.com/80.exe?1


This is Teslacrypt ransomware, although it is possible that some variants of this message may drop Locky. Both these binaries are slightly different (VirusTotal results [19] [20]) and they appear to phone home to:

vtechshop.net/wcspng.php
sappmtraining.com/wp-includes/theme-compat/wcspng.php
shirongfeng.cn/images/lurd/wcspng.php


It also attempts to contact the domain multibrandphone.com but that was not resolving at the time of analysis. It also appears to phone home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
91.234.32.192 (FOP Sedinkin Olexandr Valeriyovuch, Russia)


The domain bonjovijonqq.com is purely malicious and is hosted on the following IPs:

Malware spam: "Attached File" / canon@victimdomain.tld leads to Locky

This spam has a malicious attachment. It appears to come from within the sender's own domain. There is no body text.

From:    canon@victimdomain.tld
Date:    10 March 2016 at 09:02
Subject:    Attached File

In the sample I saw, there was an attachment victimname@victimdomain.tld_07567_273772.zip which contained a randomly-named script with a detection rate of 5/57. Automated analysis [1] [2] shows that this is the Locky ransomware, and it downloads a binary from:

buyfuntees.com/system/logs/7t6f65g.exe

This binary has a detection rate of  just 1/56. Those reports indicate that the malware phones home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
78.40.108.39 (PS Internet Company LLC, Kazakhstan)


There are probably many other download locations and some more C2s as well, I will update this post if I see them.
