MITRE ATT&CK
T1059.005 Visual Basic

The sample is identified as a legacy Excel formula macro virus, specifically 'Classic.Poppy by VicodinES' from 'The Narkotic Network'. The embedded text indicates it attempts to infect other workbooks, saving them as 'Book1.xls' in the XLSTART directory, and may deliver a payload. The presence of formula macros strongly suggests Visual Basic scripting.
