MITRE ATT&CK
T1059.005 Visual Basic

The sample is a legacy Microsoft Word document containing a WordBasic macro. The heuristic 'OLE_LEGACY_WORDBASIC_AUTOEXEC' indicates the presence of an auto-executing macro named 'AutoOpen'. The document body explicitly states the payload changes file summary information and that the 'AutoOpen' macro can be modified. ClamAV detection confirms this is a known trojan.

  • ClamAV: Win.Trojan.Alliance-13 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Alliance-13
  • 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.
