PlusServer has a PlusSized problem with Angler

PlusServer GmbH is a legitimate German hosting company. But unfortunately, the bad guys keep hosting Angler EK sites in their IP ranges over and over again.

So far I have seen many /24 blocks which have effectively been burned by out-of-control Angler (and other EK) infections. There are many individual IPs too, but below I list some of the worst blocks (links go to Pastebin).

85.25.102.0/24
85.25.107.0/24
85.25.160.0/24 
85.93.93.0/24
188.138.17.0/24
188.138.70.0/24 
188.138.71.0/24
188.138.75.0/24
188.138.102.0/24
188.138.105.0/24 
188.138.125.0/24 
217.172.189.0/24
217.172.190.0/24

Blocking these ranges will block some legitimate sites, but if Angler is causing you a problem then I would lean towards blocking those ranges and accepting the chance of some minor or moderate collateral damage. There are other bad ranges here for other hosts too.

UPDATE 2016-04-25

Here are some more PlusServer ranges where Angler has been rampant:

85.25.218.0/24
85.25.237.0/24
188.138.25.0/24
188.138.68.0/24

UPDATE 2016-05-10

Heavy Angler activity has also been spotted in the following ranges:

62.75.203.0/24
62.75.207.0/24
85.25.43.0/24 
85.25.79.0/24
85.25.159.0/24
85.25.217.0/24
188.138.33.0/24
188.138.68.0/24
188.138.125.0/24

In addition, some Angler activity has been observed in the following ranges but is not yet widespread (I will update if I see more activity):

62.75.167.0/24
85.25.41.0/24

85.25.74.0/24

85.25.106.0/24
85.25.207.0/24

188.138.41.0/24
188.138.57.0/24
188.138.69.0/24
188.138.102.0/24

PlusServer (or more likely one or more of their resellers) appear to be responsible for a large number of active Angler EK IPs (at a guesstimate, about a quarter). The problem is that some of these ranges are so badly infected (e.g. there are around 48 past and present bad IPs in 188.138.105.0/24) that the only safe option is to block traffic to those network ranges.

With black hat hosts such as Qhoster or Host Sailor and to some extent Agava you can block the entire network ranges and not block anything of value at all. In using PlusServer, the bad guys can hide their evil sites among legitimate sites where administration might fear to block something accidentally. My personal opinion is that admins need to be bold and block anyway.. it should usually be possible to block individual sites where needed.

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:

3r.com.ua/ty43ff333.exe
canadattparts.com/ty43ff333.exe
chilloutplanet.com/ty43ff333.exe
gazoccaz.com/ty43ff333.exe

silvec.com/ty43ff333.exe
tbde.com.vn/ty43ff333.exe
zecapesca.com/ty43ff333.exe

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.

Recommended blocklist:
84.19.170.249
5.135.76.18
109.234.35.0/24

Malware spam: "Envoi d’un message : 9758W-TERREDOC-RS62937-15000" / Christine Faure [c.faure@technicoflor.fr]

This French-language spam comes with a malicious attachment:

9758W-TERREDOC-RS62937-15000
Message de sécurité

To save you putting it into Google Translate, the body text reads "Your message is ready to be sent with the following file or link attached". Attached is a file 9758W-TERREDOC-RS62937-15000.zip which comes in at least eight different versions each containing a different malicious script (VirusTotal results [1] [2] [3] [4] [5] [6] [7] [8]). The Malwr reports for those samples [9] [10] [11] [12] [13] [14] [15] [16] show a malicious binary downloaded from:

store.brugomug.co.uk/765f46vb.exe

pockettypewriter.co.uk/765f46vb.exe
enduro.si/pdf/765f46vb.exe
185.130.7.22/files/qFBC5Y.exe

Note that the last file is not like the others. There may be other download locations. The "765f46vb" binary has a detection rate of 4/57 and according to all those previous reports plus these other automated analyses [17] [18] [19] [20] the malware phones home to:

83.217.8.127 (Park-web Ltd, Russia)
84.19.170.249 (300GB.ru, Russia / Keyweb, Germany)
185.117.72.94 (Host Sailor, Netherlands)
91.200.14.73 (SKS-Lugan, Ukraine)
92.63.87.134 (MWTV, Latvia)
176.31.47.100 (OVH, Germany / Unihost, SC)

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.

Recommended blocklist:
83.217.8.127
84.19.170.249

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.

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)

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:

Dear Client!

For the third time we are reminding you about your unpaid debt.

You used to ask for our advisory services in July 2015, the receipt issued to you was recognized in our database with No. 58833. But it has never been paid off.

We enclose the detailed bill for your recollection and sincerely hope that you will act nobly and responsibly.

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

Details on the individual emails vary. Attached is a ZIP file which contains one of a variety of malicious scripts (sample VirusTotal results [1] [2] [3] [4]). According to these Malwr reports [5] [6] [7] these scripts attempt to download a malicious binary from the following locations:

http://hellomississmithqq.com/69.exe?1
http://hellomississmithqq.com/80.exe?1
http://mommycantakeff.com/69.exe?1

These sites are hosted on:

74.117.183.252 (WZ Communications, US)
91.243.75.135 (Martin Andrino Ltd, Netherlands)

This Malwr report and this Hybrid Analysis shows communications with:

178.162.214.146 (Leaseweb, Germany)

The two executables seem different (VirusTotal results [1] [2]). It looks like it might be dropping both ransomware (Teslacrypt perhaps) and Dridex (banking trojan) alternately.

These domains are also associated with some of the IPs. Consider them all to be evil:

In the only sample I have seen before, there is an attached file named archive-0910001923884.docm which has a VirusTotal detection rate of 3/52. Analysis of this document is pending, but it is likely to drop either the Dridex banking trojan or Locky ransomware.

Attached is a file with a semirandom name similar to invoice_feb-92031923.doc (Sample VirusTotal report) which contains XML that looks like this [pastebin]. Malwr analysis of these samples [1] [2] shows it downloading a malicious executable from:

ratgeber-beziehung.de/5/5.exe
www.proteusnet.it/6/6.exe

If recent patterns are followed, there will be several different download locations with different versions of the file at each. I will let you know if I get these locations. The binaries has a detection rate of 7/55 and 6/54 and these Malwr reports [1] [2] [3] indicate that it phones home to:

85.25.138.187 (PlusServer AG, Germany)
31.41.47.3 (Relink Ltd, Russia)

Other samples are being analysed, but in the meantime I recommend that you block traffic to:

85.25.138.187
31.41.47.3

UPDATE 1

Some additional download locations from these Malwr reports [1] [2] [3]:

ecoledecorroy.be/1/1.exe

If you are not the intended recipient (or have received this e-mail in error) please notify the sender immediately and destroy this e-mail. Any unauthorised copying, disclosure or distribution of the material in this e-mail is strictly forbidden.

Attached is a file with a format similar to RG460634280127-SIG.zip which contains a malicious javascript in the format RG6459762168-SIG.js or similar. At the moment, I have seen two samples, both with zero detection rates at VirusTotal [1] [2]. Malwr analysis of one of the samples shows that a binary is downloaded from:

mondero.ru/system/logs/56y4g45gh45h

Other samples probably have different download locations. This executable has a detection rate of 7/53 and it appears to drop another executable with a relatively high detection rate of 26/55. Both the VirusTotal and Malwr reports indicate that this is the Locky ransomware from the people who usually push Dridex.

The malware phones home to:

46.4.239.76 (Dmitry Melnik, Ukraine / Myidealhost.com aka Hetzner, Germany)

But in fact the entire 46.4.239.64/27 range looks pretty bad and I recommend that you block it.

Incidentally, full credit to the company involved in putting this massive banner on their website warning people about the fake email..

UPDATE

An additional analysis from a trusted source (thank you). Download locations are:

In the sample I saw, the attachment was named 19875_Rechnung_2016-11365_20160215.docm and has a VirusTotal detection rate of 5/54.

According to this Malwr report  the binary attempts to download the Locky ransomware (seemingly a product of those behind the Dridex banking trojan). It attempts to download a binary from:

feestineendoos.nl/system/logs/7623dh3f.exe?.7055475

This dropped file has a detection rate of 3/53.  Analysis of the file is pending, but overall this has been made more complicated because the Locky installer calls out to a number of domains, many of which actually appear to have been sinkholed.

Machines infected with Locky will display a message similar to this:

Unfortunately, the only known way to recover from this is to restore files from offline backup once the infection has been removed from the PC.

UPDATE

Another version plopped into my inbox, VT 7/54  and according to this Malwr report, it downloads from:

nadeenk.sa/system/logs/7623dh3f.exe?.7055475

This variant POSTs to a server at:

46.4.239.76 (Myidealhost.com  / Hetzner, Germany)

It is likely that the C2 server (identified in the previous report) is:

85.25.149.246 (PlusServer AG, Germany)
