NO MALWARE

Invoice 951266 pretending to be from Sue Mockridge [smockridges2@Broad-oak.co.uk] is another one from the current zbot runs which try to drop cryptolocker, ransomware and loads of other malware on your computer. They are using email addresses and subjects that will entice a user to read the email and open the attachment. A very high proportion are being targeted at small and medium size businesses, with the hope of getting a better response than they do from consumers.  This is a continuation of the campaign shown in Santander Bank March Invoice – fake word doc malware  and Order Confirmation – Ferryfast.co.uk – fake PDF malware  where they take a genuine company email address and spoof it and pretend the emails come from that company

Lets make this perfectly clear. Sue Mockridge, Harrison Gregory or Broadoak Toiletries are not sending the emails. They have not been hacked. Their email system or server has not been compromised. What is happening is that various spammers and bots have decided to use the email address and fake emails so it looks like they are coming from Sue Mockridge. Almost every day recently a different bot has spoofed the email address and used it.

Update 18 September 2014: Another big run of this email today, with a slight change. The bot owners seem to be getting  confused and are mixing up this Broadoak Toiletries template with the recent M & M Kitchen appliances spam, malicious emails . The body content is Broad Oak but the sender is forged to appear from Sue Mockridge <sue.mockridge@mandmkitchens.co.uk>  Current Virus Total detections are 3/54

Updated 13 August 2014: they are now using Harrison Gregory or Antonia Weaver and hundreds of other made up names all pretending to be the  Accounts Administrator at Broad Oak Toiletries Ltd as the alleged sender of these spoofed emails . Today’s malware has a virus total detection rate of 2/54 The email looks almost identical to previous ones with an updated date of August  invoice and the alleged senders name changed to Harrison Gregory

Updated 1 August 2014: A new run of this spam malware laden emails pretending to come from Sue Mockridge. Today’s malware has a virus total detection rate of 2/53 The email looks identical to previous ones with an updated date of June invoice

Updated 4 August 2014: yet another massive spam run using this email. current virus total detections of today’s malware version are 1/54

25 April 2014 they have updated this campaign today, but instead of a small upatre downloader in the attachment, there is the full blown gameover Zbot

6 May 2014: another update to this one today and they are attaching what appears to be a genuine pdf file, that is malformed and has a script virus embedded. It depends on which version of Adobe reader you use, but older ones are definitely vulnerable to this exploit  and hopefully the most recent one will be safe ( but I won’t guarantee that ) As far as I can tell they are using an exploit from 2013 that was fixed  Adobe Security Bulletin Make sure you are using a version of Adobe reader that has been declared free form this vulnerability

I know we always say don’t open any attachment or file sent to you in an email, but with fake PDF files that is quite difficult. Many companies do send PDF files with invoices and it is just about impossible to tell what is real and what isn’t. It is easy to tell the normal fake PDF that is really a .exe or .scr file that has been renamed or had the .exe hidden but it is impossible to know whether a PDF file contains a virus unless you save it to your computer and scan it with your antivirus. Never open it directly from the email

Almost all of these have a password stealing component, with the aim of stealing your email or FTP ( web space) log in credentials. Many of them are also designed to specifically steal your facebook and other social network log in details.

Please read our How to protect yourselves page for simple, sensible advice on how to avoid being infected by this sort of socially engineered malware.

Email looks like this:

Hello,

Please can you let me have a payment date for the attached March Invoice?

Kind Regards

23 April 2014: Invoice 288910 March 2014 ( 10 kb)  Extracts to Invoice 288910 March 2014.exe               Current Virus total detections: 2/50

This Invoice 951266 is another one of the spoofed icon files that unless you have “show known file extensions enabled“, will look like a proper PDF file instead of the .exe file it really is, so making it much more likely for you to accidentally open it and be infected.

All of these emails use Social engineering tricks to persuade you to open the attachments that come with the email. Whether it is a message saying “look at this picture of me I took last night” and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day. Be very careful when unzipping them and make sure you have “show known file extensions enabled“, And then look carefully at the unzipped file. If it says .EXE then it is a problem and should not be run or opened.

I just got sent this and opened it by my computer wouldn’t support opening the PDF. Does this mean my computer is or isn’t infected? Is there anything I can do to protect it?

Hi Guys

I had one of these this morning but it didn’t have an attachment,( it said it did, but didn’t ) so can I assume I’m fine as I didn’t open anything other than the email?

Hello, I received this email this morning – I opened the attached zip file, then the folder, but didn’t open the .exe file inside. Is it only a problem if you open this file? I am on a mac. Many thanks for your help in advance.

I called our IT team after my mistake this morning – luckily macs find it very difficult to open these folders so you’re very unlikely to have a problem – he double checked my computer for me and all was well. So I wouldn’t worry

I have also had this 3 to 4 times today. There are also a lot going round that state you have to attend a court date and to open the attached document. I always respond to the e mail to see if it comes back as delivery failure which then tells you its spam.

once again Care2.com is being spammed by this from I’m guessing a hacked account (choicerzxp397@ontimecar.co.uk) at ontimecar.co.uk, london

Yes I received an email this morning. I know I didnt order anything from Broad-Oak in Tiverton so I suspect this is spam. I am deleting it.

Three clues to a fake – no name just ‘hello’, why would a company ask for a payment ‘date’?, and a list of nine addresses all to ‘@avnet’ and in alphabetical order.

A search on recent suspicious emails led me to this. Just to let you know, the ones we got were indeed PDFs, not exe’s. PDFs run without appropriate protections can be viable attack vectors. Everything else about it other than the month matched your description.
