Fake Your Amazon.co.uk Order Has Been Dispatched Tries To Deliver Malware

spotting malware

The next in the never ending series of malware downloaders coming from the Necurs botnet is an email with the subject of Your Amazon.co.uk order 172-3041149-3373628 has been dispatched ( random numbers) pretending to come from Amazon.co.uk <auto-shipping@amazon.co.uk>

These will be supposed to deliver either Locky Ransomware of Trickbot banking Trojan but so far I have been unable to get any payload, just the .js file which doesn’t seem to download anything from anywhere. UPDATE: found download site and it is Trickbot again today

They use email addresses and subjects that will entice a user to read the email and open the attachment.

Amazon.co.uk has not been hacked or had their email or other servers compromised. They are not sending the emails to you. They are just innocent victims in exactly the same way as every recipient of these emails.

These are very well done emails and almost believable websites that will encourage a recipient to click through and potentially be infected.

There are links in the email bodies to numerous compromised sites. All the links are in the format of < compromised site>/AmazonSignIn.html, where you see what looks like the Amazon.co.uk sign in page. An Iframe on the page automatically connects to http://wittinhohemmo.net/order.php which downloads a randomly numbered order .js file which in turn downloads the Trickbot Banking Trojan. The log in button on the webpage does go to the genuine Amazon.co.uk site. As usual you only get 1 chance at downloading the .js file per IP address. Subsequent visits give a 0 byte file.

ORDER-467-3587106-1645978.js Current Virus total detections: Payload Security | I am not seeing any actual payload downloaded or websites being contacted with this one so far

Update: after more careful manual examination I have found a download location http://storiteller.com/3f3geuf.exe ( VirusTotal) ( Payload Security ) I am not certain if actually running the .js file will deliver the payload or whether the malware devs have messed up.

Further update: I am also being told about some versions downloading Locky via http://ruisi.fr/ddokslf.exe ( VirusTotal) ( Payload Security)

it is really difficult to work out the payloads, when the .js files are created on the fly by the malware devs & seemingly at random the embedded links will differ and either deliver Locky or Trickbot or potentially any other malware the gang are being paid to distribute.

One of the emails looks like:

Screenshot:

The fake Amazon website looks like this. The Sign In button does go to the genuine Amazon.co.uk sign in page. There are no obvious signs that the sign in credentials are diverted elsewhere. All the JavaScript files in the source code of the webpage look harmless. A quick check using Google Developer tools ( network) doesn’t show any obvious network activity to any site except the genuine Amazon site.

All the alleged senders, amounts, reference numbers, Bank codes, companies, names of employees, employee positions, email addresses and phone numbers mentioned in the emails are all 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.

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.

Previous campaigns over the last few weeks have delivered numerous different download sites and malware versions. There are frequently 5 or 6 and even up to 150 download locations on some days, sometimes delivering the exactly same malware from all locations and sometimes slightly different malware versions. Locky does update at frequent intervals during the day, sometimes as quickly as every hour, so you might get a different version of these nasty Ransomware.

This is another one of the files that unless you have “show known file extensions enabled“, can easily be mistaken for a genuine DOC / PDF / JPG or other common file instead of the .EXE / .JS 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 (https://en.wikipedia.org/wiki/Social_engineering_(security)) 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. Many 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, or an invoice or order confirmation from some company, you can easily see if it is a picture or document & not a malicious program.

If you see .JS or .EXE or .COM or .PIF or .SCR or .HTA .vbs, .wsf , .jse .jar 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 a guaranteed way to get infected. The best way is to just delete the unexpected zip and not risk any infection.
