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

The sample is a Microsoft Word document containing VBA macros, specifically an AutoOpen macro that utilizes GetObject to execute code. This indicates a malicious intent to run arbitrary commands upon opening. The ClamAV detection name 'Doc.Malware.Sagent-6902893-0' further supports its malicious nature. The VBA script is heavily obfuscated, but the presence of AutoOpen and GetObject strongly suggests it's a downloader for a second-stage payload.

Heuristics 6

  • ClamAV: Doc.Malware.Sagent-6902893-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Sagent-6902893-0
  • 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.
