Update: 24 September 2018. The latest version of this scam is described https://myonlinesecurity.co.uk/trickbot-delivered-via-fake-intuit-fw-invoice-3989021-email/
This example is an email containing the subject of “Unpaid Invoice ” pretending to come from Intuit but actually coming from a look-a-like or typo-squatted domain Gary.Terry@intuit-invoice.com with a malicious word doc attachment is today’s latest spoof of a well-known company, bank or public authority delivering Trickbot banking Trojan
I haven’t seen any Trickbot directly targeted at the UK today but did receive this one later than usual to catch the USA time zones early in their working day. One item on note is that both compromised websites are hosted on same IP address and hosted by Godaddy. This might suggest a vulnerability on that server rather than a vulnerability on the individual websites, however both appear to be “owned” by the same SEO company and I do get a wordfence block on one of the sites.

Intuit 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.
What has happened is that the criminals sending these have registered various domains that look like genuine Company, Bank, Government or message sending services. Normally there is only newly registered domain that imitate Companies House, HMRC, another Government department, a Bank, file hosting service or a message sending service that can easily be confused with the genuine organisation in some way, that are hosted on & sending emails from 4 different servers.. Some days however we do see dozens or even hundreds of fake domains.
Today’s example of the spoofed domain has switched to using Tucows as registrar instead of Godaddy. ( these criminals seem to be changing between Tucows and Godaddy as the mood takes them. Because of new GDPR rules we cannot easily find the registrants name or any further details.

Continuing with the behaviour we have been seeing recently with the macros on these word docs. They are using some sort of Active X control ( looks like ink picture resize active X control today. We have been seeing ink picture paint recently) to start & run the macro, so it needs an extra couple of clicks from the victim to get infected. After enabling content I clicked and tried to drag & move the cursor a couple of times and move the mouse around at the top of the page where it looks like some sort of embedded ole object is also used. In fact today using Anyrun I could not get the macro to fire off at all. however Hybrid analysis did get the payload & download locations
This malware doc file downloads from http://edisonnjseo.com/jap.plap which is a renamed .exe file ( VirusTotal) Gtag ser 0718US
The alternate Download location is http://longbeachcaseo.com/jap.plap
The folder for files & configs has changed again today to C:\Users\ user name\AppData\Roaming\msdesk
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 spreadsheet files and PowerPoint etc that are downloaded from the web or received in an email automatically in “protected view” that stops any embedded malware, macros and DDE “exploit /Feature” and embedded ole objects 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. If the protected mode bar appears when opening the document DO NOT follow the advice they give to enable macros or enable editing to see the content. The document will have a warning message, but you will be safe.
Be aware that there are a lot of other 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 outweighing the convenience, benefits and cost of keeping an old version going.
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
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.
