Attached is a partly randomly-named file, for exampple 081155545_1735494_18836.xls - the first two numbers are random, the third is always "18836". So far I have seen just two variants of this (there may be more) with detection rates of about 5/56 [1] [2] which according to the Malwr reports [3]  [4] download a binary from the following locations:

prettymom.ru/system/logs/vbry73f34f.exe
desean.com.sg/system/logs/vbry73f34f.exe

This binary has a detection rate of 6/56. Analysis is pending, however this looks like the Dridex banking trojan.

UPDATE 1

The comments in the VirusTotal scan give some more download locations:

2.casino-engine.ru/games/megajack/vbry73f34f.exe
shop-bedep.com/system/logs/vbry73f34f.exe
17.rent-shops.ru/system/logs/vbry73f34f.exe

Curiously "Bedep" is the name of a trojan. These Hybrid Analysis reports [1] [2] [3] show malicious traffic to:

188.165.215.180 (OVH, France)

I strongly recommend that you block traffic to that IP.

UPDATE2

Some additional download locations and C&C servers to block, from another source (thank you!)

jean-daniel.com.ua/system/logs/vbry73f34f.exe
namkeendelights.com/system/logs/vbry73f34f.exe

Overall, some of these download locations look like good candidates for blocking, especially:

81.177.140.123 (Avguro Technologies Ltd, Russia)
210.245.90.206 (FPT Telecom Company, Vietnam)
89.184.72.57 (Internet Invest Ltd., Ukraine)

These additional C&C servers have been seen before:

78.108.93.186 (Majordomo LLC, Russia)
87.106.8.177 (1&1, Germany)
91.236.4.234 (FHU Climax Rafal Kraj, Poland)

So far I have seen just one sample of this, so it is possible that other companies are being spoofed as well. Attached is a file INV09BEE9.zip which in turn contains a malicious script statistics_60165140386.js. This has a detection rate of precisely zero.

This Malwr report shows that it is the Locky ransomware, download a binary from:

intuit.bitdefenderdistributor.info/intrabmw/get.php

This is hosted on a bad webserver at..

93.95.100.141 (Mediasoft ekspert, Russia)

..and it then phones home to..

5.34.183.195 (ITL / UA Servers, Ukraine)

There are probably other download locations. My contacts tell me that these are C2 servers for an earlier German-language campaign, it is possible they are being used here. Block 'em anyway..

31.184.197.119 (Petersburg Internet Network ltd., Russia)
51.254.19.227 (Dmitrii Podelko, Russia / OVH, France)

Malware spam: "Scanned image" / "Image data in PDF format has been attached to this email."

This fake document scan has a malicious attachment:

From:    admin [ands21@victimdomain.tld]
Date:    29 February 2016 at 19:05
Subject:    Scanned image

Image data in PDF format has been attached to this email.

The email appears to originate from within the victim's own domain. Attached is a randomly-named file with a format similar to 2016022936833473.zip containing a malicious script with a name somewhat like SCAN000469497.js  I have seen three different versions of the attached scripts with detection rates of around 1/55 [1] [2] [3]. The Malwr reports for those [4] [5] [6] show download locations at:

www.notebooktable.ru/system/logs/7ygvtyvb7niim.exe
svetluchok.com.ua/admin/images/7ygvtyvb7niim.exe [404]
mansolution.in.th/system/logs/7ygvtyvb7niim.exe

This appears to be Locky ransomware with a detection rate of just 3/55. Those Malwr reports also indicate C&C servers at:

51.254.19.227 (Dmitrii Podelko, Russia / OVH, France)
185.14.29.188 (ITL aka UA Servers, Ukraine)

Note that one of the download locations is 404ing. There may be other download locations that I am not aware of, howerver I recommend that you block all traffic to:

51.254.19.227
185.14.29.188

Message text

Please see attached letter and a copy of the original invoice.

Attached is a file with a semirandomly name, e.g. RG026052317614-SIG.zip which contains a malicious script. This script then downloads an executable from the same locations as found here, dropping a malicious executable with a detection rate of 10/55 (changed from earlier today).

Third party analysis (thank you) indicates that this then phones home to the following locations:

91.121.97.170/main.php (OVH, France)
46.4.239.76/main.php (Dmitry Melnik, Ukraine / Myidealhost.com aka Hetzner, Germany)
31.184.233.106/main.php (Virty.io, Russia)

So far I have seen a couple of different versions of the attachment (VirusTotal [1] [2]) which according to Malwr [3] [4] both download a malicious binary from:

5.189.216.101/dropbox/download.php

This IP belongs to LLHost Inc, Netherlands. You can assume that the IP is malicious.

The dropped binary is named rare.exe, and has an MD5 e6f67b358009f66f1a4840c1eff19c2e of and a detection rate of 4/53. The Malwr report for this shows it phoning home to:

198.50.234.211 (OVH, Canada)

The payload is the Dridex banking trojan, and this behaviour is characteristic of Botnet 120.

I have seen at least four different variations of the attachment, named in the format remittance_advice14DDA974.doc (VirusTotal results [1] [2] [3] [4]). These Malwr reports [5] [6] [7] [8] show those samples communicating with:

http://179.60.144.19/victor/onopko.php
http://5.34.183.127/victor/onopko.php

Those IPs are:
179.60.144.19 (Veraton Projects, Netherlands)
5.34.183.127 (ITL Company, Ukraine)

UPDATE 1:  this related spam run also downloads from:

91.223.88.206/victor/onopko.php

This is allocted to "Private Person Anton Malyi" in Ukraine.

A file aarab.exe is dropped (MD5 05219ea0aefedc873cecaa1f5100c617) [VT 4/53] which appears to communicate with:

198.50.234.211 (OVH, Canada)

I strongly recommend that you block traffic to that IP. The payload is the Dridex banking trojan, this attack is consistent with botnet 120.

UPDATE 2

This other Dridex 120 spam run uses different download locations:

46.17.100.209/aleksei/smertin.php
31.131.20.217/aleksei/smertin.php

The dropped "aarab.exe" file is also different, with an MD5 of c19959c2d372a7d40d4ba0f99745f114 and a detection rate of just 2/54.

I have only seen a single sample of this email at present, but if consistent with other similar emails then details such as the sender's name and reference numbers will vary. In this case, the attachment was named INV-SE723A36B7.doc and had a VirusTotal detection rate of 1/55.

According to this Malwr report, the sample attempts to download a further component:

194.28.84.79/softparade/spanish.php

There will most likely be a couple of other download locations too (check back later for more). This IP address belongs to Hostpro in Ukraine. Those other locations are likely to be in Ukraine too.

A file named hram.exe is dropped onto to target system with a detection rate of 4/54. The Malwr report indicates that this communicates with:

78.47.119.93 (Hetzner, Germany)

This is a critical IP to block, as we also saw it in use yesterday. The payload is most likely the Dridex banking trojan.

UPDATE 1

A contact (thank you) let me know of two other download locations:

176.103.62.14/softparade/spanish.php
51.254.51.178/softparade/spanish.php

These are:

176.103.62.14 (PE Ivanov Vitaliy Sergeevich, Ukraine)
51.254.51.178 (OVH, France / Dmitry Shestakov, Russia)

Both those are pretty well-known providers of malware.  I recommend that you block the entire /20 in the first instance and the blocks referenced here in the second.

UPDATE 2

An updated version of the payload is currently being spammed out as on 11.01.16, with a payload identical to this spam run.

Malware spam: "British Gas - A/c No. 602131633 - New Account" / trinity [trinity@topsource.co.uk]

The attachment is not properly formatted and appears as a Base 64 section of the email. What it should be is a malicious document named FR7000609906.doc which has a VirusTotal detection rate of 4/54.

The Malwr analysis of the document indicates that it downloads from:

www.riucreatives.com/65dfg77/kmn653.exe

This has a detection rate of 3/54 and an MD5 of d5e717617400b3c479228fa756277be1. The Malwr report and Hybrid Analysis  indicate network traffic to:

151.80.142.33 (OVH, France)

Tainted network: Dmitry Shestakov / vds24.net on OVH

vds24.net (apparently belonging to "Dmitry Shestakov ") is a Russian reseller of OVH servers that has come up on my radar a few times in the past few days [1] [2] [3] in connection with domains supporting Teslacrypt malware and acting as landing pages for the Angler exploit kit.

Curious as to what was hosted on the vds24.net I set about trying to find out their IP address ranges. This proved to be somewhat difficult as they are spread in little chunks throughout OVH's IP space. I managed to identify:

5.135.58.216/29
5.135.254.224/29
51.254.10.128/29
51.254.162.80/30
51.255.131.64/30
149.202.234.116/30
149.202.234.144/30
149.202.234.188/30
149.202.237.68/30
176.31.24.28/30
178.32.95.152/29
178.33.200.128/26

Then using a reverse DNS function, I looked up all the domains associated with those ranges (there were a LOT) and then looked the see which were active plus their SURBL and Google ratings. You can see the results of the analysis here [csv].

There may well be legitimate domains in this range, but out of 1658 domains identified, 1287 (77.6%) are flagged by SURBL as being spammy. Only 11 (0.7%) are identified as malicious, but in reality I believe this to be much higher.

In particular, the following IP ranges seem to be clearly bad from those ratings:

51.254.10.131
51.254.162.81
51.255.131.66
51.255.142.101
149.202.234.190
149.202.237.68
178.33.200.138

I can see 61 active IPs in the vds24.net range, so perhaps it is only a small proportion. However, depending on your network stance, you may want to consider blocking all the IP ranges specified above just to be on the safe side.

UPDATE

One additional range has come to light, connected with the Dridex banking trojan:

51.254.51.176/30

The sender's name is randomly-generated but is always female. Also random are the order number and value, and there is an attachment in the format invoice_12345678_scan.zip that matches the reference in the document.

Inside that ZIP file is a uniquely generated .JS file in the format invoice_XXXXXX.js or invoice_copy_XXXXXX.js which is highly obfuscated (like this) and deobfuscates to something like this.

The various versions of the macro attempts to download a binary from the following location:

miracleworld1.com/80.exe?1

I cannot get this to resolve at the moment, it turns out that the domain was only registered today.

I think they started spamming before the domain records could be pushed out fully. Shame.

Nameservers are DNS1.DONALDDUCKS.IN and DNS2.DONALDDUCKS.IN on 93.189.42.21 (NTCOM, Russia) and 178.33.200.177 (Dmitry Shestakov, Belize / OVH, France) respectively.

Looking at the nameservers, I can see that the following malicious domains are part of the same cluster, and I recommend you block all of them:

gammus.com
miracleworld1.com
soft2webextrain.com

Although I have not been able to acquire the payload, it is almost definitely Teslacrypt.

UPDATE

An updated version of the script is being spammed out that looks like this when deobfuscated. This attempts to download Teslacrypt from the following URLs:

firstwetakemanhat.com/91.exe?1
miracleworld1.com/91.exe?1

This has a detection rate of 4/55. firstwetakemanhat.com was registered just today and is hosted on:


193.150.0.78 (PE Govoruhin Vitaliy Sergeevich, Russia)
84.200.69.60 (Ideal-Hosting UG, Germany)


Nameservers are DNS1.GOGODNS.RU and DNS2.GOGODNS.RU which are hosted on the same two IPs.

The Malwr report shows more details, however this is my recommended blocklist (updated):
193.150.0.78
84.200.69.60 
gammus.com
miracleworld1.com
soft2webextrain.com
firstwetakemanhat.com

Malware sites and evil networks to block (2015-12-11)

This group of domains and IPs are related to this Teslacrypt attack, sharing infrastructure with some of the malicious domains in question. In addition to Teslacrypt, some of these are connected with PoSeidon, Pony and Gozi malware.

The analysis [csv] includes SURBL and Google ratings, ISP information and a recommended blocklist.

Malicious domains:
auth-mail.ru
blagooooossss.com
brostosoosossss.com
chromedoors.ru
debatelocator.ru
ggergregre.com
growthtoys.ru
hagurowrob.ru
hedtheresran.ru

poponkia.com
soft2webextrain.com
softextrain64.com
softextrain644.com
toftevenghertbet.ru
wordlease.ru
workcccbiz.in

Partly or wholly malicious IPs:
46.166.168.106
80.87.202.52
96.8.119.3
104.232.34.141
149.202.234.190
176.103.48.223
185.18.53.247
185.118.64.182

Recommended blocklist:
46.166.168.64/26 (Duomenu Centras, UA)
80.87.202.0/24 (JSC Server, RU)
96.8.119.0/27 (New Wave NetConnect, US)
104.232.34.128/27 (Net3 Inc, US)
149.202.234.188/30 (OVH / Dmitry Shestakov, BZ)
176.103.48.0/20 (PE Ivanov Vitaliy Sergeevich, UA)
185.18.53.247 (Fornex Hosting, NL)
185.118.64.176/28 (CloudSol LLC, Russia)

I've blocked traffic to 176.103.48.0/20 for two years with no ill-effects, it seems to be a particularly bad network. There may be a few legitimate sites hosted in these ranges, they would mostly be Russian.. so if you don't usually visit Russian websites then the collateral damage might be acceptable.

Malware spam: "INTUIT QB" / "QUICKBOOKS ONLINE [qbservices@customersupport.intuit.com]" leads to ransomware

This fake Intuit QuickBooks spam leads to malware:

From:    QUICKBOOKS ONLINE [qbservices@customersupport.intuit.com]
Date:    30 November 2015 at 10:42
Subject:    INTUIT QB


As of November 5th, 2015, we will be updating the browsers we support. We encourage you to upgrade to the latest version for the best online experience. Please proceed the following link, download and install the security update for all supported browsers to be on top with INTUIT online security!

InTuIT. | simplify the business of life

© 2015 Intuit Inc. All rights reserved. Intuit and QuickBooks are registered trademarks of Intuit Inc. Terms and conditions, features, support, pricing, and service options subject to change without notice. 

The spam is almost identical to this one which led to Nymaim ransomware.

In this particular spam, the email went to a landing page at updates.intuitdataserver-1.com/sessionid-7ec395d0628d6799669584f04027c7f6 which then attempts to download a fake Firefox update. 

This executable has a VirusTotal detection rate of 3/55, the MD5 is 592899e0eb3c06fb9fda59d03e4b5b53. The Hybrid Analysis report shows the malware attempting to POST to mlewipzrm.in which is multihomed on:

89.163.249.75 (myLoc managed IT AG, Germany)
188.209.52.228 (BlazingFast LLC, Ukraine / NForce Entertainment, Romania)
95.173.164.212 (Netinternet Bilgisayar ve Telekomunikasyon San. ve Tic. Ltd. Sti., Turkey)

The nameservers for mlewipzrm.in are NS1.REBELLECLUB.NET and NS2.REBELLECLUB.NET which are hosted on the following IPs:

210.110.198.10 (KISTI, Korea)
52.61.88.21 (Amazon AWS, US)

These nameservers support the following malicious domains:

deseondefend.com
xonstensetsat.com
dledisysteming.com
thecertisendes.com
georgino.net
tangsburan.net
rebelleclub.net
helpagregator.net

The download location uses a pair of nameservers, NS1.MOMEDEFER.PW and NS1.PRIZEBROCK.PW. If we factor in the NS2 servers as well, we get a set of malicious IPs:

5.135.237.209 (OVH, France)
196.52.21.11 (LogicWeb, US / South Africa)
75.127.2.116 (Foroquimica SL / ColoCrossing, US)

Malware spam: "Notice to Appear" / Notice_to_Appear_00800614.zip

This fake legal spam comes with a malicious attachment:

From:    District Court
Date:    22 October 2015 at 19:03
Subject:    Notice to Appear

Notice to Appear,

This is to inform you to appear in the Court on the October 27 for your case hearing.
Please, prepare all the documents relating to the case and bring them to Court on the specified date.
Note: The case may be heard by the judge in your absence if you do not come.

You can review complete details of the Court Notice in the attachment.

Sincerely,
Michael Newell,
District Clerk.

Attached is a file Notice_to_Appear_00800614.zip which in turn contains a malicious script Notice_to_Appear_00800614.doc.js which looks like this [pastebin]. This obfuscated script translates into something a bit more understandable which clearly references the following domains:

www.flowarrior.com
www.abama.org
littlefacesofpanama-association.com

The Hybrid Analysis report  shows that it downloads a file as %TEMP%\5883173.exe which has a VirusTotal detection rate of 5/55 (possibly Cridex). It reference the following IPs as being highly suspect:

91.121.108.77 (OVH, France)
78.24.220.229 (TheFirst-RU, Russia)

I have not had the change to check those individual IP addresses, but I recommend that you block the following two at least:

Note: If you do not come, the case will be heard in your absence.

You can review complete details of the Court Notice in the attachment.

Yours faithfully,
