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

The file is a malicious OLE document containing VBA macros, specifically an AutoOpen macro that uses GetObject. The presence of VBA macros and the AutoOpen function strongly suggests an attempt to execute malicious code upon opening. The script's obfuscated nature prevents a precise determination of its payload, but the overall pattern indicates a downloader or dropper.

Heuristics 6

  • ClamAV: Doc.Malware.Sagent-6914419-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Sagent-6914419-0
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen 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.
