NOTE

The current round of Word and Excel attachments are targeted at Windows users.

Apple and Android software can open these attachments and may even manage to run the macro embedded inside the attachment.

The auto-download file is normally a windows executable and so will not currently run on  any operating system, apart from Windows.

However, if you are an Apple/Android user and forward the message to a Windows user, you will them put them at risk of opening the attachment and auto-downloading the malware.

Currently these attachments try to auto-download Dridex, which is designed to

steal login information regarding your bank accounts (either by key logging, taking auto-screens hots or copying information from your clipboard (copy/paste))

Cheers,
Steve

The macro connects to one of the below dropper hosts and downloads the exe: DROPPER: hxxp://advancedheattreat.com/js/bin.exe DROPPER: hxxp://ecinteriordesign.com/js/bin.exe

It saves the files to the %temp% dir as : IHJfffFF.exe – then executes it

TheTEMP\IHJfffFF.exe file tries to connect to one of the below command and control IPs: 72.29.93.208:80 – HostDime.com Orlando, FL, USA 37.139.47.105:80 – Comfortel Ltd, St. Petersburg, Russia
