MITRE ATT&CK
T1059.005 Visual Basic

The sample is a legacy Word document containing a WordBasic macro identified by the 'AutoOpen' marker. This macro appears to be part of a 'Simple Batch Virus Maker' tool, suggesting the document's purpose is to generate and potentially execute malicious batch scripts. The presence of the 'AutoOpen' macro and the nature of the extracted text strongly indicate a malicious intent to create and distribute harmful files.

Heuristics 2

  • ClamAV: Win.Trojan.C-103 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.C-103
  • Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXEC
    OLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
