MITRE ATT&CK
T1059.005 Visual Basic

The sample is identified as malicious by ClamAV and contains a legacy WordBasic auto-exec macro marker 'AutoOpen'. This suggests the document is designed to run malicious code automatically when opened, likely to download and execute a secondary payload. The specific family could not be determined due to the legacy nature of the macro.

Heuristics 2

  • ClamAV: Win.Tool.WM-8 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Tool.WM-8
  • 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.
