multiple malware delivered from compromised website run on a domestic BT IP address

As I mentioned earlier in the week, we aren’t seeing massive amounts of malware, especially in the UK at the moment BUT we do see a steady lowish volume stream of commodity malware. These are the standard easy to purchase and use malware tools like Nanocore, Hawkeye, Agent Tesla and other keyloggers or remote access trojans that are so easy to use that they get used by both Skiddies & the criminal malware gangs.

Today’s first example is a Nanocore remote access Trojan that was delivered via a fake Swift Payment advice pretending to come from Citi Bank. So far nothing unusual or noteworthy. Until you look at the site that actually contains the malware payload:  This site is hosted on a domestic consumer BT IP number using a dynamic DNS service to direct to the site. ( BT generally only offer a domestic customer a dynamic IP address that changes very frequently, sometimes daily, sometimes you keep the same IP for 1 month or even longer).

BT do allow or rather do not disallow running a webserver on your internet connection. But the T&C for a domestic broadband connection with BT does appear to prohibit running a commercial site selling things.

This Domain does appear to be an online shop for DJ equipment, using WordPress on a home computer as the server. There is nothing wrong with anybody running a web server from their domestic IP address but you do need to know it is not as simple as it first appears and you can make several mistakes that either make the site unavailable or introduce serious security vulnerabilities. I assume from looking at the Virus Total domain report that the domain was compromised and used in a phishing a scam back in January 2019 when it was hosted by Godaddy, so the owner decided to try to run a server himself to “control” things better or more cheaply. Although he has up to date server software, WordPress, Apache, PHP etc. There must still be a serious vulnerability somewhere allowing the miscreants behind these campaigns to continue to abuse this server.

It might be something as simple as him falling for a phishing scam at some time & has given away his log in credentials allowing the criminals to misuse his server. Or a more serious compromise on his home computer or server.

I can’t easily tell if this person is running the webserver on his personal day to day computer or is using a stand alone server. But he definitely has a problem. Looking up the domain on VirusTotal we see that he was using a hosting company until fairly recently ( March 2019) Since he changed to self hosting he has been appearing in blacklists & has been serving malware pretty regularly.

I have sent a message to the website owner via his contact form on the website, but from previous experience it is extremely common for the site owner to totally ignore these reports. They either think it is a scam trying to extort money from them or sell them something ( a clear up service etc). Or they just bury their head in the sand & ignore it, hoping it will go away.

I can easily find 3 different malware files still available for download. There are probably many more. It is not uncommon for multiple malware spreading miscreants to abuse the same vulnerable servers or share login details. But it can be an indication of the same miscreant using multiple different malware versions. I obviously don’t have copies of the emails (if there were any) for the first 2 malware versions delivering Agent Tesla keylogger

As you can see the xls file is not a payment advice of any sort but contains an embedded  blurry image of a service agreement quotation for Applied Biosystems that I have seen used in dozens if not hundreds of malware campaigns. This sort of simple mistake proves that the miscreants behind this & other similar malware campaigns are buying an “off the shelf ” exploit malware delivery kit and just changing the urls in the kit, not customising it properly or effectively.

This malware downloads from

All the alleged senders, companies, names of employees, phone numbers, amounts, reference numbers etc. mentioned in the emails are all innocent and are just picked at 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 other 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.

This email attachment contains what appears to be a genuine word doc or Excel XLS spreadsheet with either a macro script or  an embedded OLE object that when run will infect you.

Modern versions of Microsoft office, that is Office 2010, 2013, 2016 and Office 365 should be automatically set to higher security to protect you.

By default protected view is enabled and  macros are disabled, UNLESS you or your company have enabled them.  If protected view mode is turned off and macros are enabled then opening this malicious word document will infect you, and simply previewing it in  windows explorer or your email client might well be enough to infect you. Definitely DO NOT follow the advice they give to enable macros or enable editing to see the content.

Most of these malicious word documents either appear to be totally blank or look something like these images when opened in protected view mode, which should be the default in Office 2010, 2013, 2016  and 365.  Some versions pretend to have a digital RSA key and say you need to enable editing and Macros to see the content.  Do NOT enable Macros or editing under any circumstances

What can be infected by this

At this time, these malicious macros only infect windows computers. They do not affect a Mac, IPhone, IPad, Blackberry, Windows phone or Android phone. The malicious word or excel file can open on any device with an office program installed, and potentially the macro will run on Windows or Mac or any other device with Microsoft Office installed. BUT the downloaded malware that the macro tries to download is windows specific, so will not harm, install or infect any other computer except a windows computer. You will not be infected if you do not have macros enabled in Excel or Word. These Macros do not run in “Office Online”  Open Office, Libre Office, Word Perfect or any other office program that can read Word or Excel files. 

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. Also please read our post about word macro malware and how to avoid being infected by them

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. It might be a simple message saying “look at this picture of me I took last night” that appears to come from a friend. It might be a scare ware message that will make you open the attachment to see what you are accused of doing. Frequently it is more targeted at somebody ( small companies etc.) who regularly receive PDF attachments or Word .doc attachments or any other common file that you use every day, for example an invoice addressed to This email address is being protected from spambots. You need JavaScript enabled to view it..

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. Many of us routinely get Word, Excel or PowerPoint attachments in the course of work or from companies that we already have a relationship with.

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. A lot of 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”, an invoice or receipt from some company for a product or service  or receive a Word doc or Excel file report that work has supposedly sent you to finish working on at the weekend,  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.

With these malformed infected word, excel and other office documents that normally contain a vba macro virus, the vital thing is do not open any office document direct from your email client or the web. Always save the document to a safe location on your computer, normally your downloads folder or your documents folder and scan it with your antivirus. Many Antiviruses do not natively detect vba  macro-viruses in real time protection and you need to enable document or office protection in the settings. Do not rely on your Anti-Virus to immediately detect the malware or malicious content.    DO NOT enable editing mode or enable macros  

All modern versions of word and other office programs, that is 2010, 2013, 2016 and 365, should open all Microsoft office documents that is word docs, excel files and PowerPoint etc  that are downloaded from the web or received in an email  automatically in “protected view” that stops any embedded malware or macros from being displayed and running. Make sure protected view is set in all office programs to protect you and your company from these sorts of attacks and do not over ride it to edit the document until you are 100% sure that it is a safe document. If the protected mode bar appears when opening the document DO NOT enable editing mode or enable macros the document will look blank or have a warning message, but will be safe.

Be aware that there are a lot of dodgy word docs spreading that WILL infect you with no action from you if you are still  using an out dated or vulnerable version of word. This is a good reason to update your office programs to a recent version and stop using office 2003 and 2007.  Many of us have continued to use older versions of word and other office programs, because  they are convenient, have the functions and settings we are used to and have never seen a need to update to the latest super-duper version.  The risks in using older version are now seriously starting to outweigh the convenience, benefits and cost of keeping an old version going.

I strongly urge you to update your office software to the latest version and stop putting yourself at risk, using old out of date software.
