MITRE ATT&CK
T1059.005 Visual Basic

The file is an OLE document containing legacy WordBasic auto-exec markers, specifically 'aUtOoPeN' and 'AUTOOPEN'. These markers indicate the presence of macros designed to run automatically when the document is opened, a common technique for malware execution. The ClamAV detection further confirms its malicious nature.

Heuristics 2

  • ClamAV: Win.Trojan.Tiny-92 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Tiny-92
  • 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.
