MITRE ATT&CK
T1059.005 Service Execution: Service Execution

The file is identified as a malicious Excel 4.0 (XLM) macro-enabled spreadsheet. The presence of 'OLE_XLM_AUTOOPEN' and 'OLE_XLM_LEGACY_MACRO_VIRUS' heuristics, specifically mentioning 'XL4Poppy', strongly indicates the use of legacy macro functionality for malicious execution. The 'RUN($B$1)' command within the macro sheet suggests that the macro is designed to execute arbitrary code, likely to download and run a secondary payload.

Heuristics 2

  • Excel 4.0 (XLM) Auto_Open + macro sheet critical OLE_XLM_AUTOOPEN
    Workbook contains an Auto_Open / Auto_Close defined name together with an Excel 4.0 macro sheet — the canonical XLM auto-execution shape used by malware families such as Emotet and QakBot.
  • Legacy XLM macro-virus family marker critical OLE_XLM_LEGACY_MACRO_VIRUS
    Workbook contains an Excel 4.0 macro Auto_Open chain and legacy macro-virus family strings. This is a narrow indicator for infected XLM workbooks rather than ordinary formula use.
