MITRE ATT&CK
T1059.005 Visual Basic

The sample is a legacy Word document from 1997 containing WordBasic macros. The presence of an 'AutoOpen' macro marker and the ClamAV detection 'Win.Trojan.WM-16' strongly indicate malicious intent. The document body contains fragmented text related to macro programming and virus creation, further supporting the malicious nature.

Heuristics 2

  • ClamAV: Win.Trojan.WM-16 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.WM-16
  • 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.
