MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The file contains VBA macros, including a Document_Open macro and a hidden UserForm command stager, which are characteristic of Emotet. The critical heuristic 'OLE_VBA_USERFORM_HIDDEN_COMMAND_STAGER' indicates the use of a hidden UserForm to execute code. The ClamAV detection 'Doc.Malware.Emotet-9370793-0' further supports the Emotet family attribution. The VBA script likely downloads and executes a second-stage payload.

Heuristics 7

  • ClamAV: Doc.Malware.Emotet-9370793-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Emotet-9370793-0
  • VBA macros detected medium 4 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • VBA UserForm hidden-property command stager critical OLE_VBA_USERFORM_HIDDEN_COMMAND_STAGER
    VBA auto-exec macro creates a COM object from a decoded variable and reconstructs command text through Split/Join and hidden UserForm properties such as ControlTipText, Tag, Pages, or HelpContextId. This is a high-confidence macro downloader/loader shape seen in the reviewed OLE set, but it is not an Office CVE exploit primitive.

  • 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.

    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.
