MITRE ATT&CK
T1059.001 PowerShell T1059.005 Visual Basic T1204.002 Malicious File

The file contains VBA macros, including a Document_Open auto-execution macro, which is a common delivery mechanism for Emotet. The ClamAV detection explicitly identifies it as 'Doc.Downloader.Emotet'. The macros likely execute a PowerShell command, as indicated by the 'OLE_VBA_PCODE_AUTOEXEC_EXEC' heuristic firing with 'CreateObject' and 'Document_open' in the stream. The document body, though heavily obfuscated, appears to contain encoded strings that may form part of the PowerShell command. The primary IOC is the extracted VBA macro file.

Heuristics 7

  • ClamAV: Doc.Downloader.Emotet-9765780-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-9765780-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject 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.
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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.
