Malware spam: "Requested document" / "The document you requested is attached" leads to Locky

This spam comes from various senders, and leads to Locky ransomware:

From:    Trudy Bonner
Date:    27 June 2016 at 15:39
Subject:    Requested document

Dear [redacted],

The document you requested is attached.

Best regards


Trudy Bonner
Group Director of Strategy
Attached is a ZIP file containing elements of the recipients email address, the words "document", "doc" or "scanned" plus a random number. Contained within is a random .js script beginning with unpaid.

Trusted external analysis (thank you as ever) shows the scripts downloading from one of the following locations:

The malware phones home to the following hosts:


51.254.240.48 (Andrey Orlov aka Relink LLC, Russia / OVH, France)
109.234.35.71 (McHost.ru, Russia)
185.82.216.61 (ITL, Bulgaria)
185.146.169.16 (Pavel Poddubniy aka CloudPro, Russia)
195.123.209.227 (ITL, Latvia)
217.12.223.88 (ITL, Ukraine)
217.12.223.89 (ITL, Ukraine)


Lots of ITL recently... you might want to block /24s here instead of single IPs.

Recommended blocklist:
51.254.240.48
109.234.35.71
185.82.216.61
185.146.169.16
195.123.209.227
217.12.223.88
217.12.223.89


Malware spam: DOC1234 / document4321 / Document56789 leads to Locky

This rather terse spam run leads to Locky ransomware and appears to come from the sender's own email account (but doesn't).

The subject is some variation of DOC / Document / document plus a number. There is a ZIP file attached with a name matching the subject, there is no body text.

Some examples

Subject: DOC541887
Attachment: DOC541887.zip

Subject: document36168
Attachment: document36168.zip

Subject: Document453567810
Attachment: Document453567810.zip

Contained within the ZIP file is one of several different .js scripts. Trusted third-party analysis (you know who you are, thank you!) shows download locations at:

calcoastlogistics.com/09ujnb76v5?yNVICJbit=nFikKFve
labthanhthanhpg.com/09ujnb76v5?yNVICJbit=nFikKFve

shadowbi.com/09ujnb76v5?yNVICJbit=nFikKFve

Detection rates for the dropped binary are 5/54. The malware phones home to the following IPs:

Malware spam: "Final version of the report" probably leads to Locky

This spam leads to malware:

From:    Julianne Pittman
Date:    23 June 2016 at 09:48
Subject:    Final version of the report

Dear info,

Patrica Ramirez asked me to send you the attached Word document, which contains the final version of the report.
Please let me know if you have any trouble with the file, and please let Patrica know if you have any questions about the contents of the report.


Kind regards


Julianne Pittman
Operations Director (CEO Designate)
The names in each version of the email vary. Attached is a ZIP file with a filename containing some version of the recipients email address and the word "report" which contains in turn a malicious ZIP .js script beginning with the words "unpaid".

The payload is not known at this time and analysis is pending, but is likely to be Locky ransomware similar to this.

UPDATE 1

Hybrid Analysis of three sample scripts [1] [2] [3] show three download locations (you can bet there will be many more):

bptec.ir/kvk9leho
promoresults.com.au/gx4al
boranwebshop.nl/ggc7ld


Each one drops a slightly different binary (VirusTotal results [4] [5] [6]) but at the moment automated analysis is inconclusive [7] [8] [9] [10] [11] [12]. I will try to post the C2 servers here if I get them.

UPDATE 2

A trusted third party analysis shows the following download locations (thank you!) :

Malware spam: "Corresponding Invoice" leads to Locky

This spam has a malicious attachment, probably leading to Locky ransomware:

From:    Althea Duke
Date:    22 June 2016 at 16:00
Subject:    Corresponding Invoice

Dear lisa:

Thank you for your email regarding your order of 21 June, and sorry for the delay in replying. I am
writing to confirm receipt of your order, and to inform you that the item you requested will be delivered
by 25 June at the latest. If you require more information regarding this order, please do not hesitate to
contact me.

Also, our records show that we have not yet received payment for the previous order of 11 June,
so I would be grateful if you could send payment as soon as possible. Please find attached the
corresponding invoice.

If there is anything else you require, our company would be pleased to help. Looking forward to
hearing from you soon.

Yours sincerely

Althea Duke
Managing Director
Who the message is "from" varies from message to message, but the body text is the same. Analysis of the payload is pending, but it is probably similar to yesterday's Locky run.

UPDATE

A little bit of analysis, via these automated reports [1] [2] [3] [4] [5] show some download locations as:

personal-architecture.nl/6gcpaey
ding-a-ling-tel.com/b289dg
plasticsmachine.com/d43ndxna
hyip-all.com/9qwmc65

Various files are dropped, including these samples [6] [7] the latter of which is a three week old version of Locky. Go figure. The comments in this report show C2 servers at:

51.254.240.48 (Andrey Orlov aka Relink LLC, Russia / OVH, France)
91.219.29.41 (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
185.82.216.55 (ITL, Bulgaria)
93.170.169.188 (PE Dunaeivskyi Denys Leonidovich, Ukraine)


Three out of those four servers are the same as yesterday.

Malware spam: "Please find attached our invoice for services rendered and additional disbursements in the above-mentioned matter."

This malicious spam leads to Locky ransomware, something that we haven't seen for several weeks:

From:    Lilian Fletcher
Date:    21 June 2016 at 20:01
Subject:    Re:

Dear lisa:

Please find attached our invoice for services rendered and additional disbursements in the above-
mentioned matter.

Hoping the above to your satisfaction, we remain.

Sincerely,
Lilian Fletcher
Head of Maintenance
These are being sent out in huge numbers at the moment. Details vary from message to message, but the body text is essentially the same. Attached is a ZIP file containing the words addition, invoice or services plus the recipients email address and a number (e.g. lisa_addition_278292.zip) containing a malicious script beginning with the word "addition".
