The sample is an Excel file identified as a legacy macro virus, specifically 'Classic.Poppy by VicodinES'. The document body contains text that appears to be a financial or work progress report, likely a lure. The embedded macro is designed to infect other workbooks, save them as 'Book1.xls' in the Excel startup directory, and potentially deliver a payload related to 'Hydrocodone/APAP 10-650'.
