MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1140 Deobfuscate/Decode Files or Information

The critical ClamAV heuristic identifies the file as 'Doc.Downloader.Emotet-9778520-0', strongly suggesting the Emotet family. The presence of VBA macros, specifically a Document_Open macro that uses CreateObject, indicates the macro is designed to execute code. The obfuscated VBA script likely attempts to download and run a secondary payload, a common Emotet tactic. The embedded URL, though benign, is noted.

Heuristics 6

  • ClamAV: Doc.Downloader.Emotet-9778520-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-9778520-0
  • 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.
  • 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.
