MITRE ATT&CK
T1059.005 Visual Basic

The critical heuristic firing indicates a legacy Excel Formula Macro Virus (Poppy by VicodinES). The document body contains text referencing 'XL4Poppy' and 'Classic.Poppy by VicodinES', along with a path that suggests an attempt to infect or modify 'Book1.xls' within the Office startup directory. This indicates the macro's intent is to spread and likely execute further malicious actions.

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.
