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

The sample is a legacy Word document containing a WordBasic auto-exec macro named 'AutoOpen'. This macro is designed to run automatically when the document is opened, indicating an attempt to execute malicious code. The presence of 'Win.Trojan.WM-12' detection further confirms its malicious nature. The document body contains strings related to macros and a specific detection name, but no direct URLs or executable commands were extracted.

Heuristics 2

  • ClamAV: Win.Trojan.WM-12 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.WM-12
  • 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.
