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

The file is a legacy Word document containing a WordBasic macro named 'aUTOoPEN', which is a known auto-execution marker. This macro is indicative of malware designed to run automatically when the document is opened, likely to download and execute a secondary payload. The ClamAV detection 'Win.Trojan.W-284' further confirms its malicious nature.

Heuristics 2

  • ClamAV: Win.Trojan.W-284 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.W-284
  • 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.
