I really don’t know what I have got here. I am totally and utterly confused by it. I don’t know if it even works or runs, or whether it just fails in anyrun or any other online sandbox, but will run on a “normal” computer.
It all starts with an email pretending to come from a lawyer with loads of gobbledegook nonsense that just doesn’t sound or look in way correct. It just tries to confuse you with various legal sounding terminology. It has the subject of “Notification report sentence #3975252142 date 16.02.2019” which has an HTML attachment to it. The html is a data : application/x-zip-compressed;base64 file which using google chrome & pressing the download button drops a zip.
This zip contains a PDF and a shortcut lnk file. The PDF isn’t actually a PDF but a renamed encoded jse file. The shortcut tells the system to copy the PDF to a new folder, then rename the copied pdf to jse & run it.
That is as far as I get. Anyrun gives error messages saying can’t open pdf. What I think is happening is that the jse should drop or download different files, including a pdf, but that doesn’t seem to happen
I am hoping one of my contacts on Twitter will be able to work out what this does.

One of the emails looks like:
From: Hadley Hedrington <email@example.com>

Subject: Notification report sentence #3975252142 date 16.02.2019
I the writer Attorney Sophie Green with office at Birningham located in Watery Lane Middleway, 973 Tax ID:935618676315 in my role as defender and domiciliary of Mr. Rilley Derrick, res. at Birningham address Watery Lane Middleway, 56
To all effects of law the decree N� 118 in original copy digital
That can be viewed at the following in the attachment (or) in a digital copy corresponding to the original computer prepared by me in civil judgment before the Tribunal of Birningham, by means of sending a email of electronic mail from my mailbox, and with complete receipt, to the your email address.
Finally, I certify that the message, in addition to the present notification report which is digitally signed, contains the following Sentence That can be downloaded at the following web address: Decrees also digitally signed: computerized copy of the document.
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.
