MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is an Excel 4.0 (XLM) macro sheet, identified by critical heuristics indicating a legacy Excel Formula Macro Virus. The document body contains explicit references to 'Classic.Poppy by VicodinES' and 'The Narkotic Network 1998', suggesting a known malware family or variant. The embedded text also indicates the macro's intent to infect a new workbook, save it as 'Book1.xls', and potentially download and execute a secondary payload, aligning with a spearphishing attachment attack vector.

Heuristics 2

  • Legacy Excel formula macro virus marker critical OLE_XLS_FORMULA_MACRO_VIRUS
    Workbook stream contains self-identifying legacy Excel formula macro virus markers. This indicates the document carries formula macro virus content even when no VBA project or modern XLM macro-sheet structure is present.
  • Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPEN
    Workbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
