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

The sample contains VBA macros, including a Document_Open auto-execution macro, which is a strong indicator of malicious intent. The macro uses CreateObject and GetObject calls, suggesting it attempts to interact with the system or download external content. The ClamAV detection further supports the malicious classification. The macro's obfuscated nature prevents a definitive analysis of its exact payload, but its presence and execution method strongly suggest it's designed to download and run a second-stage exploit.

Heuristics 7

  • ClamAV: Doc.Malware.Ewtz-9765445-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Ewtz-9765445-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • 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.
