This example is an email containing the subject of “New fax message” coming from “email@example.com ” . For a change the Trickbot criminals are not spoofing or typo-squatting any well known brand, company or Government department. Instead they are using a generic domain that looks realistic & believable.
They have also added the recipients email address into the body of the email to make it look more personalised and possibly more likely to be opened & read.

CONFIDENTIALITY NOTICE: The contents of this email message and any attachments are intended solely for the addressee(s) and may contain confidential and/or privileged information and may be legally protected from disclosure.
No well known or legitimate Fax or messaging service been hacked or had their email or other servers compromised.
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 one 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 is, as usual, registered via Godaddy as registrar. Because of new GDPR rules we cannot easily find the registrants name or any further details.

Note: Anyrun was blocked from downloading the payload and were served a fake 404 not found message. I could get the downloads via a dynamic BT UK consumer IP address. The payload also didn’t run properly on Anyrun, so it looks like the Trickbot gang have stepped up the anti-analysis / Anti-sandbox protection with this malware version. However Hybrid Analysis managed to get the payloads OK as did Cape Sandbox.
Update: It was user error at fault. I had accidentally selected the “fake net” option somehow which prevented full internet access by the sandbox. Sorry for the wrong info

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.
