Scam: 01254522444, the fake BT engineer and 888DCA60-FC0A-11CF-8F0F-00C04FD7D062

In the past few weeks I have seen a huge upsurge in the number of Indian tech support scammers ringing, both at home and my place of work. (For example.. this).

One common trick they use revolves around this hexadecimal number 888DCA60-FC0A-11CF-8F0F-00C04FD7D062. Either it's a signal that hackers are at your PC, or it's your secret router ID that only BT would know.

The conversation goes something like this..

Victim: "But I don't get my internet from BT.."

Scammer: "BT provides all the internet connections for everyone else, including TalkTalk and Virgin Media."

Victim: "How do I know you're from BT?

Scammer: "There is a confidential Router ID that only BT will know. You can verify this to prove that we are BT."

The scammer then talks the victim through pressing -R then CMD (followed by OK) and then ASSOC (followed by RETURN). That simply produces a list of file associations (e.g. to say that .xlsx is an Excel spreadsheet). The line they want you to see is:
.ZFSendToTarget=CLSID\{888DCA60-FC0A-11CF-8F0F-00C04FD7D062}
This is just something to do with how Windows  handles compressed files and folders. All Windows machines should have t his entry, but it looks sufficiently scary about to impress at least some victims.

NEVER GIVE THESE PEOPLE ACCESS TO YOUR PC.

However, if you want to waste their time please do so.. if you work in IT you can probably play a convincingly dumb user. It seems that they will try for up to 40 minutes or so before they give up. Alternatively, say that you have to get your laptop out from somewhere and it is very slow and just put them on hold. Every minute of their time you can waste will stop them targeting other potential victims.

And don't just ignore the call - report it. If you are in the UK you can report this sort of scam to Action Fraud - it will certainly help law enforcement if they have an idea of how many potential victims there are.

02085258899 - tech support scam (using anydesk.com, teamviewer.com and supremofree.com)

If these people ring you DO NOT GIVE THEM ACCESS TO YOUR PC and either hang up - or waste their time like I do.

It seems there are some prolific technical support scammers ringing from 02085258899 pretending to be from BT. They had a very heavy Indian accent, and they have made many silent calls to my telephone number before today. They claim that hackers are accessing my router.

I wasted 37 minutes of their time, these are some of the steps to watch out for..

  1. They get you to open a command prompt and type ASSOC which brings up a big long list of file associations, in particular they seem interested in one that says .ZFSendToTarget=CLSID\{888DCA60-FC0A-11CF-8F0F-00C04FD7D062}
  2. Then they get you to bring up the Event Viewer by typing EVENTVWR and then clicking "Custom Views" and "Administrative Events". This is a log file that will always show a whole bunch of meaningless errors (such as network faults). It's quite normal for this to look quite bad to the untrained eye.
  3. Then in order they try to get you to connect to the following services to take remote control of your PC: www.anydesk.com, www.teamviewer.com and www.supremofree.com. All of these are legitimate services,but I have to confess I'd never heard of the last one.. so I will add it to my corporate blacklist.
  4. When those didn't work they tried directing me to a proxy at hide.me/proxy and www.hide.me/proxy (the same thing I know) which is probably another candidate for blocking.
Of course, once they have access to your PC they will try to convince you that you need to pay them some money for technical support. Be warned, that they can render your PC unusable if you don't pay, and they can also steal confidential data. Despite how many times they may tell you they are from BT, they are not.. they are simply fraudsters.

Malware spam: "Payslip for the month Dec 2016." leads to Locky

This fake financial spam leads to Locky ransomware:

From:    PATRICA GROVES
Date:    19 December 2016 at 10:12
Subject:    Payslip for the month Dec 2016.

Dear customer,

We are sending your payslip for the month Dec 2016 as an attachment with this mail.

Note: This is an auto-generated mail. Please do not reply.
The name of the sender will vary. Attached is a malicious Word document with a name like Payslip_Dec_2016_6946345.doc which has a VirusTotal detection rate of 12/55.

This Hybrid Analysis clearly shows Locky ransomware in action when the document is opened.

According to my usual reliable source, the various versions of this download a component from one of the following locations:

Malware spam: "Amount Payable" leads to Locky

This fake financial spam leads to Locky ransomware:

From:    Lynn Drake
Date:    15 December 2016 at 09:55
Subject:    Amount Payable

Dear [redacted],
The amount payable has come to $38.29. All details are in the attachment.
Please open the file when possible.

Best Regards,

The name of the sender will vary, although the dollar amount seems consistent in all the samples I have seen. Attached is a file with a name similar to doc_6937209.zip which contains an apparently randomly-named script in a format similar to ~_ZJR8WZ_~.js. The highly obfuscated script of one sample can be seen here. Typical detection rates for the script are around 16/54.

There are many different scripts, downloading a component from one of the following locations (thanks to my usual reliable source):

According to this Malwr analysis, a DLL is dropped with a detection rate of 18/55.  This Hybrid Analysis shows the Locky infection clearly and identifies some C2s, combining this with another source gives the following list of C2 servers:

86.110.117.155/checkupdate (Rustelekom, Russia)
185.129.148.56/checkupdate (MWTV, Latvia)
185.17.120.166/checkupdate (Rustelekom, Russia)


MWTV is a known bad host, so I recommend blocking the entire /24.

Recommended blocklist:
86.110.117.155
185.129.148.0/24
185.17.120.166

Malware spam: "New(910)" leads to Locky

This spam leads to Locky ransomware:

From:    Savannah [Savannah807@victimdomain.tld]
Reply-To:    Savannah [Savannah807@victimdomain.tld]
Date:    12 December 2016 at 09:50
Subject:    New(910)

Scanned by CamScanner


Sent from Yahoo Mail on Android

The spam appears to come from a sender within the victim's own domain, but this is just a simple forgery. The attachment name is a .DOCM file matching the name in the subject. Automated analysis [1] [2] indicates that it works in a similar way to this other Locky ransomware run today.

Malware spam: "Invoice number: 947781" leads to Locky

This fake financial spam comes from multiple senders and leads to Locky ransomware:


From:    AUTUMN RHINES
Date:    12 December 2016 at 10:40
Subject:    Invoice number: 947781

Please find attached a copy of your invoice.


Tel: 0800 170 7234
Fax: 0161 850 0404

For all your stationery needs please visit Stationerybase.
The name of the sender varies, as does the fake invoice number. Attached is a .DOCM file with a filename matching that invoice number. Typical detection rates for the DOCM file are 13/56.

Automated analysis of a couple of these files [1] [2] [3] [4] show the macro downloading a component from miel-maroc.com/874ghv3  (there are probably many more locations). A DLL is dropped with a current detection rate of 11/57.

All those analyses indicate that this is Locky ransomware (Osiris variant), phoning home to:

176.121.14.95/checkupdate (Rinet LLC, Ukraine)
88.214.236.218/checkupdate (Overoptic Systems, UK / Russia)
91.219.31.14/checkupdate (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)

Malware spam: "Firewall Software" leads to Locky

This spam appears to come from multiple senders and leads to Locky ransomware:

From:    Herman Middleton
Date:    9 December 2016 at 07:40
Subject:    Firewall Software

Hey [redacted], it is Herman. You've asked me to order new firewall software for our office computers.
Done and ready. Here, in the attachment, is the full invoice of the software counteragent.

Please check it out.

King Regards,
Herman Middleton
IT Support Manager
Attached is a ZIP file with a name like f_license_5330349.zip which contains a randomly named .js script which is very highly obfuscated.

The Hybrid Analysis and Malwr report show that the script analysed downloads a component from welte.pl/mupze (there will probably be dozens of other locations) and appears to drop a DLL with a detection rate of 4/56. That Hybrid Analysis also detections C2 traffic to:

107.181.187.97/checkupdate [hostname: saluk1.example.com] (Total Server Solutions, US)
51.254.141.213/checkupdate (OVH, France)


It's worth mentioning perhaps that other Locky C2 servers seen in the past 12 hours are as follows:

91.142.90.46/checkupdate [hostname: mrn46.powerfulsecurities.com] (Miran, Russia)
195.123.209.23/checkupdate [hostame: prujio.com] (Layer6, Latvia)
185.127.24.247/checkupdate [hostname: free.example.com] (Informtehtrans, Russia)
176.121.14.95/checkupdate (Rinet LLC, Ukraine)
185.46.11.236/checkupdate (Agava, Russia)
178.159.42.248/checkupdate (Dunaevskiy Denis Leonidovich / Zomro, Ukraine)


Although some of these are from different sub-groups of Locky pushers, let's stick them all together for the sake of convenience. Note that there are a at least a couple of bad /24 blocks in there.

Recommended blocklist:
51.254.141.213
91.142.90.46
107.181.187.97
