MITRE ATT&CK
T1059.005 Visual Basic

The file is an OLE document containing a legacy WordBasic AUTOEXEC macro, which is a strong indicator of malicious intent. This macro is designed to execute automatically when the document is opened, likely to download and execute a secondary payload. The ClamAV detection further supports its classification as malware.

Heuristics 2

  • ClamAV: Win.Trojan.WMVH1-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.WMVH1-2
  • 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.
