I have received something a bit weird and wonderful this Saturday morning. I can’t quite work out what malware it is supposed to deliver. I can’t get anything & Anyrun fails using a 32 bit VM. ( a subsequent run using a W10 64 VM and setting to MITM did give the complete chain, but I still don’t know what is actually is. It looks like some sort of keylogger.
I saw a similar campaign spoofing well known delivery companies back in March 2018 where it was discovered that the delivery chain was being called ” Snatchloader” which was delivering Ramnit banking Trojan at that time.
It all starts with an email pretending to be a delivery notification with the subject of “none, Important notice about your package DSAF598011” [ probably random numbered] coming from email@example.com with a link that will download zip file containing an image and a shortcut link file which contacts a long chain of sites to eventually download a binary.
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.
It looks like the bad actors have messed up slightly while sending the emails because they have not used a correct recipient’s details in the email & instead have inserted the word “none” which should flag it to anybody receiving it.
The delivery chain in contrast is very well done & very difficult to follow.
You can now submit suspicious sites, emails and files via our Submissions system
We start with the link in the email
https://nuestradelsol.com/customer-area/pack-DSAF598011 which delivers a zip file pack-DSAF598011.zip : Extracts to: an image file & a shortcut link file pack-DSAF598011.lnk Current Virus total detections: Anyrun App W7 32 bit | Anyrun App W10 64bit using MITM |
Once you extract the link file that then contacts https://tripfod.com/aret/now.ps1 which in turn contacts https://rebomcap.eu/sload/2.0/p2.ps1 which contacts https://rebomcap.eu/sload/2.0/hostp1.txt which contacts one of these 3 sites https://rebomcap.eu/sload/,https://leasviller.eu/sload/,https://xanderfar.eu/sload/ and downloads https://rebomcap.eu/sload/documents/update.txt ( which is an encrypted certificate that gets decoded to a working .exe file ) VirusTotal
It looks like loads of screenshots and data is sent to https://rebomcap.eu/sload which has a log in panel. As usual there are masses of other .eu domains involved in this campaign. You can see the details on the Anyrun App reports
One important thing to mention is that running the lnk file ( in Anyrun VM, so I don’t know if same happens on a real computer) gives a message saying error reading file, contents are corrupted, with a yes/no option. Selecting yes runs the infection chain. I am assuming this is a fake error set to display to try to fool the victim.
One of the emails looks like:
Date: Sat 30/06/2020 07:46
Subject: none, Important notice about your package DSAF598011

If You place an Order, We are not obliged to accept that Order and the Contract between Us will only be formed if and when We accept Your Order.

Step 2 –Reviewing Your Basket

You can also enter any promotional code which You may have. Entering a valid promotional code and clicking ‘Redeem’ will update the basket total.

Step 3 – Going to Checkout
Once You have finished shopping, You can proceed to Checkout by clicking on “Continue” or by hovering over the basket icon in the top right hand corner of the page and then clicking “Checkout”.
Step 4 – Customer registration

Alternatively, you have the option to pay with PayPal at this stage by clicking on the PayPal link.
Step 5 – Completing Your Address and Delivery Details

These malicious attachments normally 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. A very high proportion are Ransomware versions that encrypt your files and demand money ( about £350/$400) to recover the files.
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.
