This email contains an invoice file for June 2014 - July 2014. Please pay invoice in full in 3 business days and reply to us.
There is an attachment INV_2014080420.zip containing a folder invoice_june2014-july2014.xls which in turn contains a malicious executable invoice_june2014-july2014.xls.scr which has a VirusTotal detection rate of 6/52. Automated analysis tools are inconclusive   about what it does.
The first part downloads a copy of Cridex from 126.96.36.199:8080/ord/1.exe which currently has a VT detection rate of 9/54. Blocking 188.8.131.52 may offer some protection.
