There seem to be several different attachments, but for the sake of simplicity I have looked at just one. The Hybrid Analysis report shows this this is a MIME attachment that downloads and executes a script from pastebin[.]com/download.php?i=C5KGsRX3 which in turn downloads a malicious executable from  193.26.217[.]220:80/bt/get3.php (Servachok LTD, Russia) which is saved as crypted.120.exe.

This executable has a VirusTotal detection rate of 4/57. The Malwr and Hybrid Analysis reports indicates traffic to (Reg.Ru, Russia) and also shows a dropped Dridex DLL with a detection rate of 3/57.
