This past week I got this attachment and this time I used CyberChef  using the same technique published by Didier  last year to do a quick analysis of the file vs using oledump. I checked the SHA256 in virustotal and it showed this file had been submitted for analysis and was identified as Emotet .
First I opened the suspicious file as input into CyberChef, next step was to applied Strings followed by Regular Expression and changed the default to URL to see if there was any URLs contained in this file.
