The critical ClamAV detection and high-severity heuristics for VBA macros, including an auto-executing Document_Open macro and CreateObject calls, strongly indicate a malicious downloader. The presence of a VBA macro file named 'macros.bas' further supports this. The ClamAV signature 'Doc.Downloader.Emotet-9780849-0' directly attributes this sample to the Emotet family, which is known for its downloader capabilities. The document body appears to be heavily obfuscated or corrupted, preventing analysis of its specific lure.

Heuristics 7

  • ClamAV: Doc.Downloader.Emotet-9780849-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-9780849-0
  • 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.
