NO MALWARE

You have received a voice mail pretending to come from Microsoft Outlook <no-reply@ random domain address > is another one from the current bot runs which try to download various Zbots, 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.

Almost all of these also have a password stealing component, with the aim of stealing your bank, PayPal or other financial details along with 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.

All the alleged senders, companies, names of employees and phone numbers mentioned in the emails are all innocent and are just picked at random. Some of these companies will exist and some won’t. Don’t try to respond by phone or email, all you will do is end up with an innocent person  or company  who have had their details spoofed and picked at random from a long list that the bad guys have previously found.  The bad guys choose companies, Government departments and organisations  with subjects that are designed to entice you or alarm you into blindly opening the attachment or clicking the link in the email to see what is happening.

Edit 9 October 2014: These You have received a voice mail pretending to come from Microsoft Outlook emails continue to come daily this week. At the start of the week we had  the same file name on all malware attached to this email template, although they did have several different sizes & file # versions. Now we are seeing random file names and file sizes and file # with lots of subtle differences to make it harder for antivirus companies to add detections for a generic detection.

Best advice I can offer is to delete any email that has an attachment that says voicemail . It is very rare nowadays for any legitimate voicemail message to be emailed to you. If you are in one of the companies that does still use email based voice messages, then seek advice from your IT support and be extremely cautious of any attachments to your emails.

Edit 13 October 2014: Today they are continuing to send this malware laden email with a slight change to the malware. Todays version continues with a zip named as a voicemail but extracting the zip gives you an order details  with the icon of a voicemail or WAV file  ORDER -000-29899449071992273764603.pdf.exe  ( numbers of course are random ) Virus Total detections are very bad  0/8 and it looks like something has gone wrong with the virus total analysis of this one

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.

The email looks like:

 

You received a voice mail : VOICE0003589463733.wav

Caller-Id: 3589463733

Message-Id: ZU1I9W

Email-Id: montag@myonlinesecurity.co.uk

 This e-mail contains a voice message.

 Download and extract the attachment to listen the message.

 Sent by Microsoft Exchange Server

 

 

 

 

7 October 2014: VOICE3589463733.wav.zip: Extracts to: VOICE000358276655116307.exe              Current Virus total detections: 10/55

This You have received a voice mail is another one of the spoofed icon files that unless you have “show known file extensions enabled“, will look like a proper wav ( sound ) file instead of the .exe file it really is, so making it much more likely for you to accidentally open it and be infected.

 Be very careful with email attachments. 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.

The basic rule is NEVER open any attachment to an email, unless you are expecting it. Now that is very easy to say but quite hard to put into practice, because we all get emails with files attached to them. Our friends and family  love to send us pictures of them doing silly things, or even cute pictures of the children or pets.

Never just blindly click on the file in your email program. Always save the file to your downloads folder, so you can check it first. Most ( if not all) malicious files that are attached to emails will have a faked extension. That is the 3 letters at the end of the file name. Unfortunately windows by default hides the file extensions so you need to Set your folder options to “show known file types. Then when you unzip the zip file that is supposed to contain the pictures of “Sally’s dog catching a ball” or a report in word document format that work has supposedly sent you to finish working on at the weekend,  you can easily see if it is a picture or document & not a malicious program. If you see .EXE or .COM or .PIF or .SCR at the end of the file name DO NOT click on it or try to open it, it will infect you.

While the malicious program is inside the zip file, it cannot harm you or automatically run. When it is just sitting unzipped in your downloads folder it won’t infect you, provided you don’t click it to run it. Just delete the zip and any extracted file and everything will be OK. You can always run a scan with your antivirus to be sure. There are some zip files that can be configured by the bad guys to automatically run the malware file when you double click the zip to extract the file. If you right click any suspicious zip file received, and select extract here or extract to folder ( after saving the zip to a folder on the computer) that risk is virtually eliminated. Never attempt to open a zip directly from your email, that is guaranteed way to get infected. The best way is to just delete the unexpected zip and not risk any infection.

oh, dear, after years of caution, fell into this one thinking it was a Dublin code and had a friend visiting there. Saved the zip. Scanned it (reported OK). Right-clicked to ‘extract’, then I’m not sure whether I ran an exe file or not but I then immediately shredded the file and the zip and the folder and then restored to 2 days ago. Should that have put me right again? Many thanks. Anne

Will I be affected if I opened the attachment on my iPhone 5s? Or do the viruses only run on Windows? Many thanks

I received this same email this morning. Unfortunately I did not think of virus. I am running Mac OSX 10.7.5. Will that affect me? I did try to open it and I am not sure if the exe ran.

mine came from this address as a zip file.

Microsoft Outlook

i received the very same email on the 7th of Oct.. I knew it was dodgy right away and scanned it with an anti malware package(SUPERantispyware) Almost immediately it returned a Trojan Alert. So, under no circumstances run this thing.

I opened the zip and double clicked on the file but nothing happened. I ran a malware check immediately which picked nothing up. Are my passwords safe, even if I change them?

I have a total of three of these stacked up in Mail on my Mac and am unable to delete them. When I try, a message drops down:
The message “You have received a voice mail” could not be moved to the mailbox “Trash — …@…com”
“872630.emlx” couldn’t be copied because you don’t have permission to access “Messages”.

Any suggestions?

this just happened to me and despite being pretty clued up I clicked on and winzip

immediately realised what I had done and checked by going to linkedin and noticed immediately my pre saved email and password needed re entering so I guess that is how they obtain my details

running AVG scan as we speak so hopefully can cleanse my pc of this

any advice gratefully received
