Heuristics 2

  • Legacy XLM macro-virus family marker critical OLE_XLM_LEGACY_MACRO_VIRUS
    Workbook contains an Excel 4.0 macro sheet and legacy macro-virus family or workbook-replication strings. This is a narrow indicator for infected XLM workbooks rather than ordinary formula use.
  • 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.
