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

The file is a malicious OLE document containing VBA macros. The 'Document_Open' macro is present and configured to execute automatically, indicating an attempt to run malicious code upon opening. The presence of a GetObject call further suggests dynamic code execution or loading of external resources. The ClamAV detection confirms its malicious nature, likely as a downloader or dropper.

  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
