This week I got an email claiming to be a YellowPages invoice with an XLS attachment containing an Excel 4.0 macro which has similarity to [1][2].

Using Didier's oledump.py tool, I checked the spreadsheet using plugin plugin_biff with option -x which show Excel 4 macros:

Next step will be to check for any embeded URL in this XLS document. I'm using plugin_biff's find option -f to see if any URL are embedded in this file:

Unfortunately the embedded URL http[:]]//fikima[.]com/axel[.]exe was taken down soon after receiving this email [3]. I checked Virustotal hash database [4] and there are no record this file was submitted before the domain was taken down. As a final step, I scanned the file with ClamAV with negative results.
