AgentTesla Keylogger and Binary Options scam

We are still not seeing massive amounts of malware currently hitting the UK. We are still seeing the commodity malware like AgentTesla keylogger / info stealer, Nanocore RAT and Hawkeye Keylogger on a very regular basis.

Today’s example of an AgentTesla campaign is somewhat more interesting than usual.

The email is nothing special and pretends to be the typical fake invoice we frequently see as the lure with these campaigns. What is different today is firstly the email is actually coming from the sender it says it is and passes all authentication. ( see email headers below)   The home page of this website simply says this is a mail-in-a-box take control of your email at https://mailinabox.email/  The link leads to the instruction page telling you how to set up your own mailserver with a simple few clicks.

Then we get to the actual AgentTesla payload.

INV-GF76370-7478-465.cab ( VirusTotal)  : Extracts to:  INV-GF76370-7478-465.exe             Current Virus total detectionsAnyrun|

This was quite well detected on VirusTotal and there is nothing really special about the payload until you come to the email address and smtp server being used to exfiltrate the stolen information.

Anyrun has a setting to act as MITM between samples being run & the servers etc it contacts. This particular one has the email address, mail server log in& password in base64 encoded format as well as the sending & receiving email address in plain txt   This email address is being protected from spambots. You need JavaScript enabled to view it. : newpassword216!  The password is unbelievable.  and anyone using passwords like that deserves to be hacked.

I can’t say with any certainty whether the Binary Scam website has been hacked or whether the stolen data from the AgentTesla keylogger is being used by the criminals that are also behind the Binary Options scam.

But when we look up the domain in the email address tendertradeforex.co.uk  you soon find out that it is unlikely that it has been hacked or compromised, but if has been the criminals running the website deserve it. There is no honour amongst thieves.   The website itself is a total scam, is a copy  of another known scam website ( now closed) with false contact information. This site is  pushing a binary options scam. I have absolutely no sympathy when one gang of criminals hacks another gang of criminals.

Warning: these scams are illegal and in the UK, you need to be registered to provide financial advice. I am 100% sure that the names alleged to be the traders here are fake. The street address does not exist. The phone number doesn’t track to any known company and is within a range of numbers known to be used by VOIP scammers that cold call random numbers for fraudulent purposes. The only people who ever make any money from these scams are the criminals behind them.

Fake Invoice Email

Fake Invoice Email

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.
