MITRE ATT&CK
T1059.001 PowerShell T1059.005 Visual Basic T1218.011 System Binary Proxy Execution: Rundll32

The sample contains VBA macros, specifically an AutoOpen macro, which is designed to execute automatically upon opening the document. The critical heuristic 'OLE_VBA_WMI_PROCESS_CREATE' indicates that the macro attempts to launch a process using WMI's Win32_Process.Create method. This suggests the macro's primary function is to download and execute a second-stage payload. The ClamAV detection 'Doc.Malware.Sagent-6961490-0' further confirms its malicious nature.

Heuristics 7

  • VBA WMI Win32_Process launcher critical OLE_VBA_WMI_PROCESS_CREATE
    VBA macro builds or references a WMI moniker for Win32_Process and invokes .Create to start a command. This is a high-confidence macro execution chain that often hides the WMI class name through string concatenation or helper functions.
  • ClamAV: Doc.Malware.Sagent-6961490-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Sagent-6961490-0
  • 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.
