Additional Order (Additional Items) Malspam Delivering Java Adwind Backdoor Trojan

Trojan

An email with the subject of Additional Order (Additional Items) pretending to come from Ahmed <Ahmed@malothgroups.com> with a java .jar which is a variant of Java Adwind Trojan. These are very nasty backdoor Remote Access, password stealers. The immense danger of JAVA files being sent by email cannot be overstressed. JAVA is a cross browser/ cross OS language and JAVA works on any operating system, Windows, Apple MAC and Linux and even Android and Chromebook, if you have Sun Java installed. This is why JAVA is so dangerous, we have been warning for years not to have it installed unless you actually need it and use it. The vast majority of consumers and small business users do not need it and it just opens massive avenues of compromise on a computer.

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.

malothgroups.com or any other variant of that domain listed in the body of the email or the from line in the header has 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. None of the company names listed appear to actually exist., however I am getting very weird & wonderful look ups and trackbacks when trying to work out the actual sender, where somewhere along the line we have Securi website protection company involved.

Email headers for the sender are:

Now I assume from this that Securi cloud proxy on the main hostpapavps.com site is masking or redirecting the lookups, so we aren’t getting the correct picture here

One of the emails looks like:

Screenshot:

Luckily for many recipients as you can see from the screenshot Outlook and several other email clients will automatically block all unzipped JAVA .jar files and prevent them being accessed by the user, without a lot of hassle. So you cannot accidentally run them. BUT most webmail services and several common email clients will allow unfettered access to any file received by 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.

29 June 2016 : PO_70386804.jar Current Virus total detections: Payload Security shows a contact with a Russian IP number 185.17.1.82 which is fairly well known for malicious activity over the last few weeks although nothing appearing on VirusTotal, until today

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 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.
