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

The file is detected as malicious by ClamAV with the signature 'Doc.Dropper.Emotet-7535927-0', indicating it is likely an Emotet variant. The presence of a Document_Open macro, GetObject call, and VBA p-code auto-execution strongly suggests that the macro is designed to run automatically when the document is opened. This macro likely downloads and executes a secondary payload, a common Emotet delivery technique. The embedded URL was confirmed benign, so the payload delivery mechanism is not directly observable from this sample.

Heuristics 6

  • ClamAV: Doc.Dropper.Emotet-7535927-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Emotet-7535927-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • 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.
