MITRE ATT&CK
T1059.005 Visual Basic

The file is a legacy Word document containing a WordBasic macro triggered by the AutoOpen event. The document body is crafted as a letter to a magazine editor, detailing a fabricated story about a student creating macro viruses. This is a social engineering tactic to mask the malicious intent of the embedded macro, which is likely designed to execute malicious code upon opening.

Heuristics 2

  • ClamAV: Win.Trojan.WM-9 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.WM-9
  • 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.
