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

The sample contains a VBA macro that is automatically executed upon opening the document, as indicated by the Document_Open and OLE_VBA_PCODE_AUTOEXEC_EXEC heuristics. The macro uses CreateObject and GetObject calls, suggesting it attempts to interact with the system or download external content. The obfuscated nature of the VBA code, combined with the critical ClamAV detection, strongly suggests it's designed to download and execute a secondary malicious payload.

Heuristics 7

  • ClamAV: Doc.Malware.Ewtz-9765424-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Ewtz-9765424-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
