Yet another fake or spoofed DHL delivery notification delivering what today turns out to be Remcos RAT .
An email with the subject of “READ : (DHL Express) -Delivery Address Confirmation” Pretending to come from dhlSender@dhl.com <noreply@dhI.com> with a link in the email to download a word doc that in turn will download & run Remcos Rat
They use 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.
What makes this one slightly worse than usual is the location of the word doc. The criminals sending these are abusing the Box.com file storage & delivery system to deliver the malware. Box is seen as a legitimate hosting service so links to them generally don’t get blocked by mail filters or Antivruses.
Important Notice: Box.com have no way of reporting abuse of their services or malware on their system UNLESS you register an account with them & fill in a support ticket, That is something I am not prepared to do.
The link in the email to download the malicious word doc is https://officedocu.box.com/s/ik98dgivg36pvxlypbmg990udwv07od1
The domain sending the emails looks like it has been set up deliberately by the criminals to be used in malware campaigns. It was registered on 15 March 2018 with all public details redacted for privacy.
dhllogisticservice.com currently behind Cloudflare, However as you can see from the email header section the emails were sent from dhllogisticservice.com on IP 188.8.131.52. I cannot see any website running on that IP address or domain. I get a 502 Cloudflare Error.

The email looks like:

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.
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 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.
