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

The critical ClamAV heuristic indicates this is a Win.Trojan.Macro. The presence of a legacy WordBasic AUTOOPEN macro suggests the document is designed to automatically execute malicious code when opened. This macro likely serves as a loader for a secondary payload, although the specific download mechanism and target are not detailed in the extracted evidence.

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.
