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

The file is an Excel document containing a Workbook_Open VBA macro, which is a common technique for executing malicious code when the document is opened. The macro attempts to run other procedures like 'Report_OnOpen', 'GenerierenMain', 'DruckenMain', and 'ParameterauswahlMain', suggesting it's designed to initiate a multi-stage attack. The presence of the Environ() call indicates it may be attempting to gather system information or locate specific paths for payload execution.

Heuristics 5

  • Workbook_Open macro high OLE_VBA_WBOPEN
    Workbook_Open macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Environ() call (env variable access) low OLE_VBA_ENVIRON
    Environ() call (env variable access)
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
    URL http://www.iec.ch
  • Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATED
    The document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
