Moar Locky 2016-11-25

This data comes from my trusted usual source, so far I have only seen a single example.

This morning's spam run has a subject with one of the following words:

DOC
DOCUMENT
FAX
IMG
LABEL
ORD
PHOTO
PIC
SCAN
SHEET

..plus a four digit random number. Attached is a ZIP file with a name mating the subject, containing a randomly-named malicious javascript that attempts to download a component from one of the following locations:

Malware spam: "financial records subpoena" / lawfirmofoklahoma.com

This spam purports to come from Michael T Diver who is a real Oklahoma attorney, but it doesn't really and is jut a simple forgery:

From:    MICHAEL T. DIVER [michael -at- lawfirmofoklahoma.com]
Date:    23 November 2016 at 15:24
Subject:    RE:RE: financial records subpoena

See you in court !!!

Subpoena for server

Thank you,

MICHAEL T. DIVER

T (405) 608-4990

F (405) 608-4991

The telephone number and also potentially the email address are genuine, but they are certainly not being sent from this law firm.

The link in the email goes to a legitimate but hacked Vietnamese site at techsmart.vn/backup2/get.php?id=[base64-encoded-part] (the last bit is a Base 64 representation of the victim's email address).

In testing the payload site was down, but previous emails of this type have lead to the Vawtrak banking trojan.

Moar Locky: "Bill-12345" from victim's own domain

This spam has no body text and appears to come from within the sender's own domain. It leads to Locky ransomware. For example:

From:    julia newenham [julia.newenham@victimdomain.tld]
Date:    23 November 2016 at 10:44

Malware spam "Please Pay Attention" leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Please Pay Attention
From:     Bill Rivera
Date:     Wednesday, 23 November 2016, 9:45

Dear [redacted], we have received your payment but the amount was not full.
Probably, this occurred due to taxes we take from the amount.
All the details are in the attachment - please check it out.

The name of the sender will vary. In the sample I analysed, a ZIP file was attached with a filename beginning
lastpayment_ followed by the first part of the recipients email address. This archive contains a randomly-named malicious .JS script that looks like this.

This particular script (and there will be others) downloads a malicious component from one of the following locations:

nielsredeker.nl/gmcoirnrm
gurlfanam.net/krwjx
vedicmotet.com/61y7mljr4
praam.cz/iessl
nightpeople.co.il/xklqq33nr

According to this Malwr report a malicious DLL is dropped with an MD5 of def0d0070d4aed411b84ebd713fd8b92 and a detection rate of 6/56.

The Hybrid Analysis clearly shows the ransomware in action and shows it communicating with the following URLs:

95.213.186.93/information.cgi [hostname: djaksa.airplexalator.com] (Selectel, Russia)
195.123.209.8/information.cgi [hostname: kostya234.itldc-customer.net] (Layer6, Latvia)

Malware spam: "Invoice 123456" from random sender in victim's own domain

This fake financial spam appears to come from a random sender in the victim's own domain, but this is just a simple forgery. The payload is Locky ransomware.

Subject:     Invoice 5639438
From:     random sender (random.sender@victimdomain.tld)
Date:     Tuesday, 22 November 2016, 8:43

Attached is the document 'Invoice 5639438'.

The reference number varies from email to email, but is consistent in the subject, body and the name of the attachment (e.g. Invoice 5639438.zip). This ZIP file contains a malicious WSF script (e.g. Invoice 7868933153.wsf) that looks like this.

According the the Malwr analysis, that script downloads from:

manage.parafx.com/98y4h?AdIXigNCmu=UdJVux

There are no doubt many other locations. That same analysis shows a DLL being dropped with an MD5 of de5d8250edf98262f335cd87fe6f6740 and a detection rate of 9/56. The Hybrid Analysis of the same sample shows the malware contacting the following C2 locations:

89.108.73.124/information.cgi (Agava, Russia)
91.211.119.98/information.cgi (Zharkov Mukola Mukolayovuch aka 0x2a.com.ua, Ukraine)

Malware spam: "Delivery status" leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Delivery status
From:     Gilbert Hancock
Date:     Tuesday, 22 November 2016, 8:51

Dear Client! Our delivery department could not accept your operation due to a problem with your current account.
In order to avoid falling into arrears and getting charged, please fill out the document in the attachment as soon as possible and send it to us.

In the sample I analysed there was an attachment named document_recipientname.zip (i.e. the first part of the recipient's email address was in the name), containing a malicious javascript with a random name. This particular script (and there are probably many others) attempts to download a component from one of the following locations:

sbdma.com/ri3xnzkaoz
robertocostama.com/qpnst8glsz
kettycoony.com/ahkzls3w
sadhekoala.com/efgqy4tdw
sdwsgs.com/voh7

According to this Malwr analysis, a malicious DLL is dropped with an MD5 of ebf03567c2a907705a026ff0821d8e63 and a detection rate of 6/55. The Hybrid Analysis reveals the following C2 locations:

91.201.202.130/information.cgi [hostname: dominfo.dp.ua] (FLP Anoprienko Artem Arkadevich aka host-ua.com, Ukraine)
95.213.186.93/information.cgi [hostname: djaksa.airplexalator.com] (Selectel, Russia)
188.120.250.138/information.cgi [hostname: olezhkakovtonyuk.fvds.ru] (TheFirst-RU, Russia)
213.32.66.16/information.cgi (OVH, France)

For those Russian and Ukranian networks I would be tempted to block the entire /24 at least, but this is my minimum recommended blocklist:

91.201.202.130

The link in the email actually goes to a page at reg.vn/en/view_bill.php?id=encoded-email-address  (where the last part is the email address in Base 64 encoding). It downloads a malicious document lgm_bill69290.doc with a current detection rate of 8/55.

Something evil on 64.20.51.16/29 (customer of Interserver, Inc)

I wrote about this evil network on 64.20.51.16/29 (a customer of Interserver, Inc) over a year ago, identifying it as a hotbed of fraud. Usually these bad networks don't hang around for very long, but in this case it seems to be very persistent.

This time it came to notice from a terse spam with a PDF attached:

From:    Lisa Liang [ineedu98@hanmail.net]
To:    me@yahoo.com
Date:    20 November 2016 at 23:23
Subject:    11/21/2016 Amended

FYI

Attached is a file Amended copy.pdf which when you open it (not recommended) looks blurry with "VIEW" in big red letters.

The link in the email goes to bit.ly/2fJbyol - if you put the "+" on the end of a Bitly link then you can see the number of clickthroughs and what the landing page is (www.serviceupgrade.tech/pdf.php in this case).

Clicking through gives you a login page for "Adobe PDF Online" which is of course a generic phishing page.

Analysis of the 64.20.51.16/29 range finds 193 sites historically connected with it marked as being phishing or some other malicious activity. There are at least 284 sites currently within that range, of which the following are both hosted in that range currently and are malicious:

sparvicharityfoundation.com
ftp.eurocontrol-int.net
eurocontrol-int.net
bocusin.com
eurocontrol-int.net
meclp.com
lntedg.com
bs-shipmanagements.com

zharmonics-online.com
nahpa-vn.com
djhexport.com
paypalcenter.com
victorialmpex.com
schmiditsports.com
lindner-stofftiere.com
novady.top

11% of the total sites in the range have been tagged by SURBL or Google as being bad, and to be honest there are probably a LOT more but those services haven't caught up yet.

In any case, there seems to be nothing of value in 64.20.51.16/29 and I strongly recommend that you block traffic to the entire range.

The link in the email leads to updatemicrosoftonline.com on 89.248.168.13 (Quasi Networks LTD, Seychelles). Despite the email and the domain name it leads to an HMRC-themed phishing page..

This multi-phish page has twelve UK banks set up on it:

• Barclays
• Halifax
• HSBC
• Lloyds Bank
• NatWest
• Royal Bank of Scotland
• Santander
• TSB
• Metro Bank
• Clydesdale Bank
• The Co-Operative Bank
• Tesco Bank

Clicking on any of the links goes to a pretty convincing looking phish page, personalised for each bank and carefully extracting all the information they need for account theft.  The screenshots below are the sequence if you choose TSB bank.

Once you have entered all the information, the process appears to fail and you are directed to a genuine HMRC site instead.

A list of sites found in 89.248.168.0/24 can be found here [pastebin]. I suggest that the entire network range looks questionable and should be blocked.

Sender names vary, but the error in the subject persists in all versions. Attached is a ZIP file with a name beginning with "ebill" (e.g. ebill209962.zip) which contains a malicious .WSF script (e.g. 18EQ13378042.wsf) that looks like this.

For one sample script, the Hybrid Analysis and Malwr report indicate a binary is downloaded from one of the following locations:

alamanconsulting.at/0ftce4?aGiszrIV=gRLYYDHSna
naka-dent.mobi/0ftce4?aGiszrIV=gRLYYDHSna

This drops a malicious DLL with an MD5 of c1b0b1fb4aa56418ef48421c58ad1b58 and a detection rate of 13/56.

85.143.212.23/message.php (PrdmService LLC, Russia)
158.69.223.5/message.php (OVH, Canada)

These are the same C2s as seen here.

Malware spam: "Account temporarily suspended" leads to Locky

This fake financial spam leads to Locky ransomware:

From:    Nicole Roman
Date:    9 November 2016 at 10:44
Subject:    Account temporarily suspended

Dear Customer.

You have exceeded the limit of operations on your credit card.
Thus, we have temporarily blocked your account.
The full itemization of transactions and instructions are given in the document attached to this message.

Best regards.

The name of the sender varies. In the sample I looked at, the attachment was named after the recipient plus a random number, containing a randomly-named malicious .js script that looks like this

That particular script attempts to download a binary from one of the following locations (you can be sure there are others);

hippaupsup.com/3gc7c2rp
melkar.com/icfi5mg
inspireyouths.org/j48tb3
ausulifer.net/3xwpi
koratwifi.info/io4h3

This Hybrid Analysis and this Malwr report show a DLL being dropped with an MD5 of f86d98b1a67952f290c550db1c0bdcbc and a detection rate of 9/56.

No C2 locations have been identified yet. I will post them here if I get them.

Malware spam: "Suspicious movements" leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Suspicious movements
From:     Marlene Parrish
Date:     Tuesday, 8 November 2016, 12:52

Dear [redacted], Leroy from the bank notified us about the suspicious movements on out account.
Examine the attached scanned record. If you need more information, feel free to contact me.

Washington, DC 20415-1000

The names, addresses and telephone numbers will vary from message to message. Attached is a ZIP file (e.g. pdf_recipient_3608c4a.zip) which contains a malicious javascript (e.g. NRV_J51E8_.js) which looks like this (note the insane amount of whitespace).

That particular script downloads a malicious component from one of the following locations:

vexerrais.net/6sbdh
centinel.ca/wkr1j6n
3-50-90.ru/u4y5t
alpermetalsanayi.com/vuvls
flurrbinh.net/6mz3c5q

There will probably be other download locations. This Hybrid Analysis and this Malwr report show the Locky ransomware in action. This version of Locky does not appear to use C2 servers, but instead drops a malicious DLL with an MD5 of 75e6faf192d00b296d89df2cd56c454a and a detection rate of 9/56.

UPDATE

My usual reliable source (thank you) informs me that there are indeed C2 servers (see the end of the post). The download locations are as follows:

Malware spam: "Statement" leads to Locky

Another terse fake financial spam leading to Locky ransomware:

Subject:     Statement
From:     accounts@somedomain.tld
Date:     Tuesday, 8 November 2016, 10:59

For your Information.

The sender domain varies. Attached is a ZIP file with a name similar to Statement PDF - 56765041263.zip which in turn contains a malicious WSF script (like this) named in a format similar to SLM245260-0214.wsf.

Hybrid Analysis of this one sample shows a download occurring from:

gpstrackerbali.com/67j5hg?LzQWruaaLHv=dIYfuCrkfcG

There will no doubt be many other locations, if I get more information then I will post it here. The script drops a DLL with a detection rate of 14/56 and the malware appears to phone home to:

185.118.66.90/message.php (vpsville.ru, Russia)
158.69.223.5/message.php (OVH, Canada)

Recommended blocklist:
185.118.66.90
158.69.223.5

Malware spam: "Financial documents" leads to Locky

The never-ending Locky ransomware onslaught continues. This fake financial spam has a malicious attachment:

Subject:     Financial documents
From:     Judy Herman
To:     [redacted]
Date:     Monday, 7 November 2016, 10:53

Hi [redacted],

These financial documents need to be uploaded on the system.
Please let me know if you experience any technical problems.

Best Wishes,
Judy Herman 

Sender names will probably vary. In the sample I saw there was an attachment named fin_docs_f73856f4.zip containing a malicious script NRV_A194008F_.vbs that looks like this. This particular script (and there will be others like it) attempts to download from:

http://coachatelier.nl/lg8s2
http://bechsautomobiler.dk/m8idi9j
http://desertkingwaterproofing.com/ma4562
http://zapashydro.net/6sgto2bd
http://owkcon.com/6xgohg6i

According to this Hybrid Analysis, the malware then phones home to:

195.123.211.229/message.php [hostname: panteleev.zomro.com] (Layer6 Networks, Bulgaria / ITLDC, Latvia)
185.67.0.102/message.php [hostname: endgo.ru] (Hostpro Ltd. / hostpro.com.ua, Ukraine)
188.65.211.181/message.php (Knopp, Russia)

Recommended blocklist:
195.123.211.229
185.67.0.102
188.65.211.181

Malware spam: "!!! Urgent payment request" from random senders leads to Locky

This spam comes from random senders, the name in the "From" field always matches the fake email signature. The number of exclamation marks varies, and the payload is Locky ransomware.

Subject:     !!! Urgent payment request
From:     erika.whitwell@hillcrestlife.org (erika.whitwell@hillcrestlife.org)
Date:     Thursday, 3 November 2016, 10:01

ERIKA WHITWELL

Telefon: +49 1592 / 51-2545
Fax: +49 1592 / 5166-2545
E-Mail: erika.whitwell@hillcrestlife.org

Attached is a file with a long name made of random numbers (e.g. 5148202750-2115939053-201611153218-5476.zip) which contains a similarly-named malicious javascript file (e.g. 8357243996-7378883150-201611233647-0661.js) which looks like this [pastebin].

Analysis is pending. Please check back later.

UPDATE

This Hybrid Analysis shows the script downloading from:

dornovametoda.sk/jhb6576?jPUTusVX=GXNaiircxm

There will be lots of other download locations too. That same report shows the malware phoning come to the following C2 servers (that overlaps somewhat with those found here):

194.28.87.26/message.php (Hostpro Ltd, Ukraine)
93.170.123.119/message.php (PE Gornostay Mikhailo Ivanovich aka time-host.net, Ukraine)

Malware spam: "Companies House - new company complaint" / noreply@companies-house.me.uk / noreply@companieshouses.co.uk leads to TrickBot

This fake Companies House spam leads to TrickBot malware:

Subject:    Companies House - new company complaint
Signed by:    companieshouses.co.uk

Unlike recent Locky spam runs, this TrickBot run has gone to a lot of effort to look authentic.

The sender is either noreply@companies-house.me.uk or noreply@companieshouses.co.uk - both those domains have actually been registered by the spammers with fake WHOIS details:

    Registrant:
        Camell Williams

    Registrant type:
        Unknown

    Registrant's address:
        550 HOLTS LAKE CT STE 101
        Suite 101
        Apopka
        Florida
        32703
        United States

Both those domains are close to the genuine one of companieshouse.gov.uk and because the email is digitally signed it might get past spam filters where normal botnet-sent spam wouldn't.

All the emails that I have seen have been sent via servers at 172.99.84.190 and 172.99.88.226 (a Rackspace customer apparently called OnMetal v2 IAD PROD). I recommend that you block email traffic from those IPs.

Attached is a Word document Complaint.doc  (MD5 21AEA31907D50EE6F894B15A8939A48F) [VT 7/55] which according to this Hybrid Analysis downloads a binary from:

futuras.com/img/dododocdoc.exe

This is saved as sweezy.exe and has a detection rate of 7/57. At present that download location is down, probably due to exceeding bandwidth quota.

The Hybrid Analysis identifies several C2s which overlap with this TrickBot run from yesterday:

78.47.139.102 (Unknown customer of Hetzner, Germany)
91.219.28.58 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
91.219.28.77 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
193.9.28.24 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
193.107.111.164 (PP "Kremen Alliance", Ukraine)
193.124.177.117 (MAROSNET, Russia)

The uadomen.com IP ranges (as discussed yesterday) are a sea of badness and I recommend you block traffic to them.

Recommended blocklist:
78.47.139.96/28
91.219.28.0/22
193.9.28.0/24
193.107.111.164
193.124.177.117

Malware spam: "New Fax Message" / administrator@local-fax.com leads to TrickBot

This fake fax leads to TrickBot which appears to be similar to the Dyre banking trojan that we saw a lot of last year..

From:    Administrator [administrator@local-fax.com]
To:    annie@[redacted]
Date:    1 November 2016 at 13:28
Subject:    New Fax Message
Signed by:    local-fax.com

Confidential Fax

Recipient: annie@[redacted]
From: +443021881211
Attn:
Important document: For internal use only
The documents are ready. Check attached file for more information.

Attached is a Word document (in this case Internal_Fax.doc) which has a pretty low detection rate at VirusTotal of 5/54. Both the Malwr report and Hybrid Analysis give some clues as to what is going on, but in fact the Malwr report comes out with a binary download location of:

www.tessaban.com/img/safafaasfasdddd.exe

This is a hacked legitimate website. Downloading that file manually and resubmitting it gives two rather more interesting Malwr and Hybrid Analysis reports give the following suspect traffic:

91.219.28.77 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
193.9.28.24 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
37.1.209.51 (3NT Solutions LLP, UK)
138.201.44.28 (Philip Diver, Australia / Hetzner, Germany)
23.23.107.79 (Amazon EC2, US)

I can match all those IPs except the last to this ThreatGeek report, those IPs are a mix of what looks like dynamic IPs for hacked home users and static ones (highlighted):

5.12.28.0 (RCS & RDS Residential, Romania)
27.208.131.97 (China Unicom, China)
36.37.176.6 (VietTel, Cambodia)
37.1.209.51 (3NT Solutions LLP, UK)
37.109.52.75 (Cyfrowy Polsat, Poland)
46.22.211.34 (Inferno Solutions aka 3NT Solutions LLP, UK)
68.179.234.69 (ECTISP, US)
91.219.28.77 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
91.219.28.103 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
104.250.138.194 (Sean Sweeney, US / Gorillaservers, US)
138.201.44.28 (Philip Diver, Australia / Hetzner, Germany)
188.116.23.98 (NEPHAX, Poland)
188.138.1.53 (PlusServer, Germany)
193.9.28.24 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)

3NT Solutions (aka Inferno Solutions / inferno.name) are very, very bad news and I would recommend blocking any IPs you can find for this outfit. FLP Kochenov Aleksej Vladislavovich aka uadomen.com has appeared here so many times [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] that really I have to categorise that as an Evil Network too.

If we excise the domestic IPs and blackhole the 3NT / Inferno / uadomen.com ranges we get a recommended blocklist of:

37.1.208.0/21
46.22.211.0/24
91.219.28.0/22
104.250.138.192/27
138.201.44.28
188.116.23.98
188.138.1.53
193.9.28.0/24

However, there's more to this too. The original email message is actually signed by local-fax.com and it turns out that this domain was created just today with anonymous registration details. The sending IP was 104.130.246.8 (Rackspace, US) and it also turns out that this is widely blacklisted and is probably worth blocking.

All the samples I have seen show a consistent MD5 of e6d2863e97523d2f0e398545989666e4 for the attachment, and all the recipients I have seen begin with the letter "a" curiously enough..
