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

The file contains legacy WordBasic macro markers, specifically 'AutoOpen', which is a known indicator of malicious macro execution. The ClamAV detection as 'Win.Trojan.Simple-7' further supports its malicious nature. The presence of 'AutoOpen' suggests an attempt to automatically run code when the document is opened, likely for downloading additional malware.

Heuristics 2

  • ClamAV: Win.Trojan.Simple-7 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Simple-7
  • 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.
