MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious OLE document containing VBA macros. The 'Document_Open' macro and 'CreateObject' calls indicate that the macro is designed to execute code. ClamAV detection identifies it as 'Doc.Dropper.EmotetiBlueUpdate1020-9780531-0', suggesting it acts as a dropper for further malicious payloads. The VBA script itself is heavily obfuscated but the presence of macro execution and the dropper heuristic strongly suggest a malicious intent to download and execute a second-stage payload.

Heuristics 6

  • ClamAV: Doc.Dropper.EmotetiBlueUpdate1020-9780531-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.EmotetiBlueUpdate1020-9780531-0
  • 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.
