It is definitely a Freaky Friday today. Loads of malware hitting UK, although it is Good Friday & a Public Holiday in UK with most businesses closed for the long Easter Weekend holidays and nothing open till Tuesday.
An email pretending to be a My Hermes notification of delivery with the subject of “Order AW_369_0420_3C Confirmed” coming from firstname.lastname@example.org with a link in the email to download a zip file.
The headers appear to show this coming via the Mailchimp network, But I think that part of the headers are forged. None of the actual sending IPs appear to be anything to do with Mailchimp. This just doesn’t feel like Mailchimp are associated with this one.
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, although this one does seem more consumer targeted from the email.
My Hermes or any other delivery company mentioned in these emails have 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
Now this is where the delivery chain gets complicated & involved:
It starts with the link in the email to https://kdotcombooking.com/customer.info/AW_369_0420_3C-order-info Where a zip file is downloaded.
This lnk file downloads http://updatesoftures.com/orders/boston.ps1 ( which I cannot get anything from & get a 403 trying) but Anyrun could get something. This shows a bits admin connection to https://updatesoftures.com/orders/bett12est.txt ( VirusTotal) which downloads an encrypted certificate file which has the malware payload embedded inside it which is decoded/extracted by the certutil utility built in to windows on the computer to give fder43hg.exe (VirusTotal) | Anyrun |Hybrid Analysis |
I am not certain what this is yet, but is does give indications of keylogger capabilities. It is connecting to or attempting to connect to hundreds of random named .eu domains, as well as contacting Baidu for something.
Update: the general consensus is that the downloader is a version of Snatchloader that is delivering what looks like Ramnit banking trojan payload
Update 5 April 2018: there has been a very worrying update to this malware delivery method. I have been informed that today’s emails have the correct full details of the recipient. That is Full name, Full address, correct mobile or other phone number.
We cannot currently confirm where this personal information in the emails has come from. It must have come from one of the breaches or dumps that has been posted over recent months or years. The only thing in common I can find from 2 email addresses that have sent me details is that both are listed in Have I Been Pwned with details from the onliner spambot dump ( But I wasn’t previously aware that real addresses & phone numbers were in that dump.
I haven’t received any myself, but a couple of recipients have commented in the comments & I have been sent one copy via our submissions system. I can’t get any eventual payload today myself from the links, but they are, at least in the initial stages, the same sites as stated above updatesoftures.com. starting with http://updatesoftures.com/tmp/gr45wq.ps1 which is giving me a 403 forbidden. These emails are imitating various delivery companies.
Update, one of the researchers managed to download the PS1 & get the payload https://updatesoftures.com/tmp/er12t1.txt which needs decoding via certutil to give Ramnit banking trojan ( anyrun )
There are loads of links in the bodies of the emails, so far I have been informed about these
Update 6 April 2018: Another run of this today with some changes. Main change is to the site hosting the ps1 & txt file which has switched from updatesoftures.com to fordekoms.com. I haven’t seen the email yet today & am only going on the link to the zip I was sent.
Original link is to https://getfitgal.com/delivery/3463-DA-036-ZV1-orders which delivers 3463-DA-036-ZV1-orders.zip ( VirusTotal) ( Anyrun ) containing a .lnk file which downloads https://fordekoms.com/df12a/gf3412a.ps1 ( VirusTotal) which is encrypted /encoded but in turn downloads https://fordekoms.com/df12a/fhq12a.txt ( VirusTotal) which is an encrypted certificate which is decoded by certutil.exe to give gf54rt32t.exe ( VirusTotal )
All files in today’s zip ( P/W “infected” )
Starts with https://crtdigital.com/orders/4203.WMB-564_46E-order 404 for me when I tried but original recipient got the full chain and the zip containing a lnk file that goes to https://fordekoms.com/rw3q5/l4e12b.ps1 which uses bitsadmin to download from https://fordekoms.com/rw3q5/u83qw21a.txt and uses certutil.exe to decode to frty521q.exe which in turn downloads sfsmcmjr.exe but I can’t actually see where from in the Anyrun report

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.
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. Dridex /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 or Banking password stealer Trojans.
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.
