This document contains VBA macros that disable macro protection and attempt to replicate themselves. The script also contains logic to potentially download and execute further payloads, indicated by the `AddIns.Unload True` and `Kill Options.DefaultFilePath(8) & "\*.doc"` commands, suggesting a downloader or dropper functionality. The presence of `Options.VirusProtection = False` and `Application.EnableCancelKey = wdCancelDisabled` points to an attempt to evade detection and user intervention.

Heuristics 4

  • ClamAV: Doc.Trojan.Marker-35 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-35
  • VBA macros detected medium 2 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • VBA macro-virus self-replication / AV tampering critical OLE_VBA_MACRO_VIRUS_REPLICATION
    VBA macro programmatically rewrites VBA project code through the VBE object model (CodeModule/VBComponents InsertLines/DeleteLines/AddFromString or OrganizerCopy) to copy itself into the global template and other open documents, and/or disables Office macro-virus protection (Options.VirusProtection = False). This is the defining behavior of the W97M document macro-virus family — self-replicating code with no benign document use, independent of any AV signature.
