MITRE ATT&CK
T1059.005 Visual Basic

The file is an OLE document from 1992, containing legacy WordBasic AUTOOPEN macro markers. ClamAV identifies it as Win.Trojan.Macro-11. The presence of AUTOOPEN suggests an attempt to automatically execute malicious code when the document is opened, a common technique for macro-based malware.

Heuristics 2

  • ClamAV: Win.Trojan.Macro-11 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Macro-11
  • 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.
